107 Double Layer Milky Serum Review 2026: Worth It?

Two layers sit inside one small bottle. A golden oil floats on top. A clear watery serum rests below. You shake it, and suddenly you hold a soft milky liquid that looks like melted pearl. That single moment is why the 107 Double Layer Milky Serum keeps showing up on beauty shelves, in reels, and in shopping carts through 2026.

But a satisfying shake does not equal good skin. So I bought a bottle, used it twice a day for six weeks, and tracked every result. I checked the full ingredient list. I compared it against cheaper Korean serums. I also noted the moments it annoyed me, because a review without complaints is just an advertisement.

This post covers the unboxing, the texture, the real timeline of results, the price math, and the exact skin types that should walk away from this bottle. You will also find three solid alternatives if this one does not fit your face or your budget. By the end, you will know if the hype earns your money.

In a Nutshell:

• The format solves a real problem. The oil layer carries lipids. The water layer carries humectants. One shake delivers both in a single step, so dry skin often skips a separate face oil.
• The hydration is instant, the firming is slow. Skin looked plump and dewy on day one. Bounce and tone improved gradually between week four and week eight, not overnight.
• Ginseng exosomes are the headline, not the proof. Panax ginseng root protoplasts and hydrolyzed ginseng saponins are exciting, yet independent clinical evidence for topical exosomes stays thin. Niacinamide, adenosine, and the nine type hyaluronic acid complex do the heavy lifting.
• It is gentle and fragrance free. No added fragrance, no essential oils, no alcohol, no parabens. Sensitive and reactive skin handled it well in my test.
• It is not for everyone. Sunflower oil, sweet almond oil, and esters make it a poor pick for fungal acne. The almond oil also matters for tree nut allergies.
• The price feels fair. Around 29 dollars for 50ml, and one bottle lasted me close to ten weeks with twice daily use.

The 107 Double Layer Milky Serum is a two phase Korean face serum in a 50ml bottle, which equals 1.69 fluid ounces. The brand behind it, 107 or oneoseven, launched in Korea around 2017 and built its name on fermented ingredients like aged vinegar and lactobacillus ferment.

This serum sits in the middle of a routine. You apply it after toner and before moisturizer. It targets three things at once: hydration, firmness, and dull tone. The brand also mentions redness reduction and barrier support.

The star claim is ginseng exosome technology. On the label, that appears as Panax ginseng root protoplasts plus hydrolyzed ginseng saponins. Supporting that story is a seven year aged vinegar, a nine type hyaluronic acid complex, plantago seed extract rich in glucuronic acid, and niacinamide.

The two layers stay separate in the bottle by design. Oil and water do not mix on their own, so 107 skipped heavy emulsifiers and asked you to do the mixing instead. You shake, the phases blend into a milky emulsion, and that emulsion holds together just long enough to spread across your face.

It is vegan, cruelty free, and formulated without synthetic fragrance, alcohol, parabens, silicones, sulfates, and mineral oils. The period after opening is twelve months.

Unboxing Experience and First Impressions

The box is small, matte, and quiet. No foil stamping, no loud claims across the front. 107 keeps its packaging simple, which fits a brand built on fermentation rather than flash. Inside, the bottle sits in a snug paper cradle with a short leaflet.

The bottle itself is the fun part. It is clear glass, so you can see both layers on the shelf, and that visual is honestly half the appeal. The golden oil band sits above the pale watery base like a tiny science experiment. My partner picked it up twice just to look at it.

The cap holds a dropper. Pressure feels light and controlled, and I never got a flooded pipette. That matters here, because you dose a blended emulsion and it starts separating again within a minute or two.

First shake took about five seconds of firm wrist work. The liquid turned soft ivory, slightly opaque, with no bubbles or foam. Smell was faint and clean, with a very light sour edge from the vinegar and ferments. It is not perfumed and it does not smell like a spa product.

First application felt richer than a normal watery essence but lighter than a cream. Absorption took about sixty seconds. No sting, no tingle, no tightness. My cheeks looked slightly glossy for around ten minutes, then settled into a soft finish.

Key Ingredients Inside the 107 Double Layer Milky Serum

The formula reads better than the marketing, which is a rare and welcome flip. Here is what actually earns attention.

Niacinamide sits eighth on the list, so the level is meaningful. This is one of the best studied cosmetic actives available. It supports ceramide production, strengthens a stressed barrier, and softens uneven tone and brown spots over time.

Nine forms of hyaluronic acid fill the water phase. You get standard sodium hyaluronate, hydrolyzed versions, a crosspolymer, silanol variants, potassium hyaluronate, and more. Different molecular sizes hold water at different depths, so the plumping feels layered rather than surface only. The crosspolymer is the standout, since it releases bound water slowly instead of all at once.

Adenosine appears too. Korea approves it as a functional wrinkle ingredient, and it has real clinical support for fine lines and firmness.

Sunflower seed oil and sweet almond oil build the milky layer. Sunflower oil is high in linoleic acid and speeds barrier recovery. Almond oil softens and smooths.

Lactobacillus ferment and vinegar bring the brand signature. The ferment has soothing and antimicrobial data behind it, and it suits sensitive or reactive skin.

Ginseng exosomes carry the firming story. Ginseng has a long antioxidant pedigree, and plant protoplast delivery is a genuinely active research field. Still, treat this as a promising bonus rather than settled science.

How the Two Layers Actually Work

The two phase idea is not decoration. Water loving ingredients and oil loving ingredients refuse to share space without help. Most brands solve this with emulsifiers and thickeners, which changes the feel and sometimes weakens the oil phase.

107 took the other road. The bottle keeps the phases apart until you shake, so the oils stay pure and the humectants stay fully hydrated. You mix a fresh emulsion every single time you use it.

Here is what that means on skin. The water phase pulls moisture into the upper layers of your face. The oil phase then sits on top and slows evaporation. In practical terms, hydration lands and stays put instead of drifting off into dry air.

That combination explains why my skin felt comfortable for hours rather than thirsty by lunchtime. I stopped needing a midday mist within the first week.

The trade off is timing. Once blended, the emulsion begins separating again within a couple of minutes. So you shake, you dispense, you apply, and you move. Leaving a filled dropper on the counter while you scroll your phone gives you a partially split dose.

Temperature matters slightly too. On cold mornings the oil layer thickens, and the shake takes a few extra seconds to fully combine. Warming the bottle in your palm fixes it fast.

Texture, Scent, and Skin Feel

After mixing, the liquid looks like thin milk with a faint champagne tint. It pours rather than drips, and three to four drops covered my whole face and neck comfortably.

Spread is easy and slippery. There is no grabbing, no pilling, and no rolling into little balls under a moisturizer, which is more than I can say for several silicone heavy serums I have tested. It layers cleanly under sunscreen, which is where many milky serums fail.

The finish is dewy but not wet. My combination skin looked healthy rather than shiny, and my forehead did not turn into a mirror by noon. On my drier cheeks, the softness lasted well into the evening.

Scent is the part people ask about most. There is no added fragrance, so what you smell is the formula itself: a light, slightly grainy sourness from vinegar and ferment, plus a faint nutty note from the oils. It fades in under a minute. If fermented skincare has ever bothered your nose, this one is mild by comparison.

Under makeup, it behaved well after a five minute wait. Rushing it caused slight separation at my nose. With that short pause, foundation sat smooth and looked less powdery than usual.

My Six Week Test Results

I used it morning and night on clean, toned skin, and I changed nothing else in my routine so the results stayed readable.

Week one delivered the obvious win: hydration. My skin felt cushioned, and the dry patch near my jaw calmed down by day four. Makeup looked better almost immediately, mostly because the surface was smoother.

Week two and three brought a subtle tone shift. Redness across my cheeks softened, and the overall look grew more even. Nothing dramatic, but visible in daylight photos taken in the same spot each week.

Week four to six is where the firmness claim showed a little life. My skin felt bouncier when pressed, and the fine crepey texture under my eyes looked less papery. Deeper lines did not move. Anyone expecting a lifted jawline from a serum will be disappointed, and honestly no serum should promise that.

Breakouts stayed at my normal baseline. No congestion appeared along my hairline or chin, which surprised me given the oil content.

The honest summary: hydration and comfort scored high, tone scored moderate, and firming scored mild but real. The results also faded within about two weeks after I stopped, which tells you this is maintenance rather than permanent change.

Pros and Cons of the 107 Double Layer Milky Serum

Every product has both sides. Here is mine after six weeks of daily use.

Pros

• Two phase delivery works. Lipids and humectants land in one step, so drier skin can drop an extra oil from the routine and save a stage.
• Hydration is immediate and lasting. The nine form hyaluronic complex holds moisture at several depths, and skin stays comfortable for hours.
• Niacinamide and adenosine are proven. Both have solid research behind them for barrier support, tone, and fine lines, which grounds the formula in real science.
• Fragrance free and alcohol free. Sensitive, reactive, and rosacea prone skin will appreciate the short irritant list and gentle profile.
• Light, non greasy finish. It layers under sunscreen and makeup without pilling, which many milky textures cannot manage.
• Fair price for the formula. Around 29 dollars for 50ml, and a bottle stretches roughly two to three months.
• Vegan, cruelty free, recyclable packaging. The clean formulation list is genuinely long and specific rather than vague.

Cons

• You must shake before every use. Skip it and you get an uneven dose of mostly oil or mostly water.
• Not fungal acne safe. Sunflower oil, almond oil, and esters can feed malassezia, so fungal acne sufferers should avoid it.
• Contains sweet almond oil. That is a tree nut derivative, so severe nut allergies need caution and a patch test.
• Exosome evidence is emerging. The headline technology lacks strong independent clinical proof at cosmetic levels.
• Firming stays gentle. Expect gradual bounce, not visible lifting or wrinkle erasure.
• Only one size exists. No travel version and no larger value bottle.
• The dropper adds friction. Shake, dose, apply, repeat. It is slower than a pump.

What This Serum Does Not Do Well

Authentic reviews name the weak spots, so let me be direct.

It does not erase wrinkles. My established forehead lines looked identical on day one and day forty two. The formula smooths surface texture through hydration, and hydration always flatters fine lines temporarily. That is not the same as structural change.

It does not fade dark spots quickly. Niacinamide helps tone over months, not weeks. If pigmentation is your main concern, a dedicated vitamin C, tranexamic acid, or retinoid product will move faster.

It does not suit fungal acne. This is the clearest disqualifier. The oils and esters in the milky layer can worsen malassezia driven bumps, no matter how gentle the rest of the formula reads.

It does not replace a moisturizer for very dry skin. In winter, I still needed a cream on top. The oil phase is light, not occlusive.

It does not control oil. Very oily skin may find the finish slightly too rich by afternoon. A gel moisturizer on top helped, but the serum itself does not mattify.

It does not offer a travel size. Glass bottles and dropper caps are a poor mix with luggage, and there is no smaller option.

It does not prove its own headline. The exosome angle is interesting marketing built on young science. Buy this for the hyaluronic acid, niacinamide, ferments, and oils. Treat the ginseng as a bonus.

Who Should Buy the 107 Double Layer Milky Serum

This serum fits a specific person well, and that person is easy to describe.

Dry and normal skin gets the most value. The oil phase adds nourishment that a plain hyaluronic serum simply cannot provide, and the humectant load stops that classic tight feeling after cleansing.

Combination skin does well too. Mine did. The finish stayed light enough for my oilier zones while still comforting my dry cheeks. Pairing it with a gel moisturizer keeps the balance right.

Sensitive and reactive skin is a strong match. No added fragrance, no essential oils, no alcohol, no drying actives. Lactobacillus ferment and niacinamide both support calm, resilient skin.

Mature skin will like the texture payoff. The mix of lipids and multiple hyaluronic weights makes skin look softer and less papery. Several reviewers in their fifties reported exactly this.

Fans of fermented Korean skincare should try it. If you already enjoy vinegar and ferment based products, this fits your shelf naturally.

People who want fewer steps benefit. One shake replaces a hydrating essence plus a face oil, which trims a routine without losing anything.

Anyone tired of sticky serums will notice the difference too. This one dries down soft instead of tacky, so nothing clings to your hair on a windy day.

Who Should Skip It

Skip it if you manage fungal acne. This is not a maybe. The sunflower oil, sweet almond oil, and ester content can feed malassezia and undo weeks of progress.

Skip it if you have a serious tree nut allergy. Sweet almond oil is nut derived. A patch test behind the ear is the minimum precaution, and avoiding it entirely is reasonable.

Skip it if you want fast, dramatic anti aging results. A prescription retinoid or a well formulated retinal product outperforms this for wrinkles by a wide margin. This serum plays a supporting role.

Skip it if shaking a bottle twice a day annoys you. That sounds trivial until you are running late. Some people genuinely dislike the ritual, and there is no shame in preferring a pump.

Skip it if your skin is very oily and congestion prone. The finish may feel too cushioned, and a lightweight watery essence will serve you better.

Skip it if you need a large volume product. Fifty milliliters at this price is fine, yet body wide or heavy users will burn through it fast.

Finally, skip it if you are already using five hydrating products. Adding another humectant layer to a saturated routine changes very little. Fix the moisturizer or the barrier first, then decide.

How to Use It the Right Way

Order matters, and so does technique.

Step one: shake firmly. Five to ten seconds until the liquid turns uniformly milky. Hold it up to the light and check. If you see streaks, keep going.

Step two: cleanse and tone first. Apply on skin that is still slightly damp. Damp skin gives humectants something to grab, and it improves spread noticeably.

Step three: dose three to four drops. Press them between your palms, then pat over your face and neck. Patting beats rubbing here, because the emulsion breaks less.

Step four: wait sixty seconds. Let it settle before the next layer. Rushing causes patchiness under sunscreen.

Step five: seal with moisturizer. In the morning, finish with broad spectrum sunscreen. Dry skin can go heavier at night; oily skin can use a gel.

Frequency: twice daily works, and once at night is enough if your skin runs oily.

Pairings to be careful with: use it after a strong exfoliating acid, not before, and give retinoids their own slot in your routine. This serum actually buffers retinoid dryness nicely when applied first.

Storage: keep it away from direct sun and radiators. Heat encourages the phases to behave oddly and shortens the life of the oils.

Price and Value Breakdown

The serum runs around 29 dollars for 50ml, which lands squarely in the mid range for Korean skincare and well below most Western serums that advertise exosome technology.

Do the math on usage. Three to four drops twice a day worked out to roughly ten weeks for me. That is about 0.40 dollars per day, or 1.20 dollars per week. For a product replacing both a hydrating essence and a facial oil, that math looks good.

Compare it upward. Plenty of exosome branded serums sit between 90 and 250 dollars for 30ml, often with shorter ingredient lists and added fragrance. This one gives you niacinamide, adenosine, nine hyaluronic forms, ferments, and two nourishing oils for a fraction of that.

Compare it downward and the picture shifts. Snail mucin essences and ginseng toners cost less per milliliter and hydrate well. They just do not deliver lipids in the same step.

Where value drops: if you only want basic hydration, cheaper options exist. If you need aggressive wrinkle correction, your money belongs in a retinoid instead.

Verdict on value: fair to good. Not a bargain, not a splurge. You pay a reasonable amount for a loaded, gentle, fragrance free formula from a brand with a real fermentation track record. That is an honest exchange.

107 Double Layer Milky Serum vs Popular Rivals

Against COSRX Advanced Snail 96 Mucin Power Essence, the 107 wins on lipids and loses on simplicity. Snail mucin is thicker, tackier, and cheaper per milliliter. It excels at repair and healing. The 107 feels lighter, absorbs faster, and adds oils that mucin cannot supply. Snail mucin is also the safer pick for fungal acne.

Against Beauty of Joseon Ginseng Essence Water, the comparison is about role. The Joseon product is a watery toner with 80 percent ginseng water and niacinamide, and it costs less. It hydrates and preps. The 107 is a heavier treatment step with a full nine form hyaluronic complex and a nourishing oil phase. Many people happily use both, one after the other.

Against MISSHA Time Revolution The First Treatment Essence 5X, you are comparing a ferment first essence against a ferment plus lipid serum. Missha delivers that classic watery ferment glow and a large bottle for the price. The 107 gives richer comfort and a more targeted firming angle.

So where does the 107 sit? It is the pick when your skin wants both moisture and nourishment in one step. If your skin needs only water, cheaper rivals do that job. If your skin needs oils and water together without pilling, this one earns its place.

Final Verdict: Is It Worth Buying in 2026?

Yes, for the right skin. The 107 Double Layer Milky Serum is a well built, gentle, fragrance free serum that delivers exactly what its format promises. Hydration arrives instantly. Comfort lasts through the day. Tone and bounce improve slowly and modestly over a month or two.

The ginseng exosome headline is the weakest part of the story, and I would rather 107 led with the nine form hyaluronic acid, the meaningful niacinamide level, and the adenosine. Those ingredients are why my skin improved. The exosomes are a promising extra, nothing more.

Buy it if you have dry, normal, combination, sensitive, or mature skin and you want fewer steps without losing moisture. Skip it if you manage fungal acne, carry a nut allergy, chase dramatic wrinkle correction, or resent shaking a bottle twice a day.

At around 29 dollars for a bottle that lasts two to three months, the value holds up well against both cheaper essences and wildly overpriced exosome serums. It is a smart, sensible, quietly enjoyable product rather than a miracle. The shake is fun. The skin feel is lovely. The claims stay mostly honest.

That combination makes it one of the more recommendable Korean serums on the shelf this year.

Frequently Asked Questions

Do I really need to shake the 107 Double Layer Milky Serum every time?

Yes. The oil and water phases separate naturally within minutes. Shake for five to ten seconds until the liquid looks uniformly milky. Without that step, you dispense mostly one phase, and the balance of oils and humectants disappears.

Is the 107 Double Layer Milky Serum fungal acne safe?

No. It contains sunflower seed oil, sweet almond oil, and several esters that can feed malassezia. Anyone actively managing fungal acne should choose an oil free hydrating essence instead, no matter how gentle the rest of the formula is.

Can I use it with retinol or vitamin C?

Yes, with sensible spacing. Apply the serum first at night to cushion a retinoid, since the oils and hyaluronic acid reduce dryness. With vitamin C in the morning, let the vitamin C absorb fully, then layer this serum on top before sunscreen.

How long until I see results?

Hydration and dewiness show up on the first application. Tone evenness usually appears around week two or three. Firmness and bounce build gradually between week four and week eight of consistent twice daily use.

Is it safe during pregnancy?

The ingredient list contains no retinoids, no hydroquinone, and no high strength acids, which makes it a low concern formula. Still, pregnancy skincare choices belong with your own doctor, so confirm with your obstetrician or dermatologist before adding it.

How long does one bottle last?

The 50ml bottle lasted me close to ten weeks with morning and night use. Lighter users who apply it only at night should expect three months or slightly more.

Does it work for oily skin?

It can, though the finish may feel richer than oily skin prefers. Use it at night only, apply two drops instead of four, and follow with a lightweight gel moisturizer.
