02 · Editorial analysis

The full review.

There is a certain audacity in building a skincare product that is 97% active ingredients. Most products hide their hero ingredients somewhere in the middle of a thirty-ingredient list, buffered by emollients, stabilizers, and botanical extracts that may or may not do anything meaningful. Purito’s Galacto Niacin 97 Power Essence flips that equation entirely: 92% galactomyces ferment filtrate, 5% niacinamide, and just fifteen total ingredients to round out the formula. The math leaves only 3% of the bottle for preservatives, pH adjusters, and a handful of supporting actives. It is radical transparency in a bottle.

Galactomyces ferment filtrate is the K-beauty world’s answer to the question of what happens when you let beneficial yeast do its work and then collect the aftermath. The fermentation process produces a nutrient-dense liquid rich in amino acids, vitamins (particularly B vitamins), minerals, and organic acids that the skin can readily absorb. It is the same family of ingredients that powers SK-II’s legendary Pitera — though Purito delivers it at a stated 92% concentration for a fraction of that luxury price.

What makes galactomyces interesting is not any single mechanism but the aggregate effect of delivering all these micronutrients simultaneously. Users consistently describe a gradual brightening and refinement of skin texture — as though the skin’s own processes are being gently optimized. The ferment also contributes to maintaining the skin’s acid mantle and supporting the moisture barrier, creating a healthier canvas for other products.

The 5% niacinamide is the precision instrument in this otherwise broad-spectrum formula. At this specific concentration — the same used in most clinical studies — niacinamide inhibits melanosome transfer (brightening dark spots), strengthens the skin barrier by boosting ceramide synthesis, and helps regulate sebum production (refining pore appearance). The galactomyces base is not just a vehicle here — it creates an optimized, nutrient-rich environment that likely enhances niacinamide absorption and efficacy.

The supporting ingredients are minimal but purposeful. Bacillus/soybean ferment extract adds a secondary layer of fermented amino acids and brightening isoflavones. Lactobacillus ferment contributes probiotic-derived compounds that support the skin microbiome. Allantoin provides gentle soothing. Adenosine — recognized as an anti-wrinkle functional ingredient by Korean regulatory standards — adds an anti-aging element. And dipotassium glycyrrhizate, a licorice root derivative, brings both anti-inflammatory and melanin-inhibiting properties. Each ingredient earns its place.

The texture is pure essence — watery, barely viscous, and so fast-absorbing that it seems to vanish on contact. You dispense a dropperful into your palm, pat it across your face, and within seconds your skin simply looks slightly dewier, as though it has just been freshly cleansed and hydrated. There is no film, no residue, no interference with subsequent products. This makes it an ideal layering essence that slots effortlessly into virtually any routine.

The absence of fragrance, alcohol, silicones, oils, parabens, and sulfates makes the ingredient list read like a sensitivity checklist turned on its head. Everything that commonly triggers reactions has been excluded. The formula is also fungal acne safe — a claim that very few fermented essences can make, since many contain esters and fatty acids that feed Malassezia yeast. The one caveat is that galactomyces itself is a yeast-derived ingredient, and while the filtration process removes the organisms, individuals with documented yeast sensitivity should still patch test.

The honest limitation of this product is subtlety. Nobody applies the Galacto Niacin 97 and immediately sees their dark spots fade or their pores shrink. The effects accumulate over weeks — a gradual brightening, a slow refinement of texture, a general improvement in skin clarity that you notice one morning in the mirror without being able to pinpoint exactly when it started. For skincare enthusiasts who want to see and feel instant results, this patience requirement can be frustrating.

The bottle is also small. At 60 ml with twice-daily use, expect to go through a bottle every six to eight weeks. At roughly $18 per bottle, the annual cost is moderate but not negligible — about $120-150 per year. That said, the per-milliliter cost is far below luxury galactomyces essences, and the cleaner, shorter ingredient list arguably delivers better value per active.

Purito has been making this essence since 2017 — it was one of the brand’s original products, predating the sunscreen controversy that later defined so much of Purito’s public narrative. The Galacto Niacin 97 has been quietly building a loyal following among K-beauty enthusiasts who appreciate that you do not need a complicated formula to achieve genuinely good skin. Sometimes all you need is a glass bottle, fifteen ingredients, and the discipline to let fermentation and niacinamide do their steady, unglamorous work.

The science.

The Science

The two main ingredients — galactomyces ferment filtrate and niacinamide — use complementary evidence. Research on Pitera (SK-II's branded version) brought galactomyces ferment filtrate to scientific attention. Studies show galactomyces-derived ferments contain amino acids, organic acids, vitamins, and minerals that improve skin texture, hydration, and radiance. A study in the Journal of Drugs in Dermatology found that topical galactomyces ferment filtrate improves skin smoothness, reduces wrinkles, and improves pore appearance.

Niacinamide at 5% has one of the strongest evidence bases in cosmetic dermatology. The Hakozaki et al. study (2002, British Journal of Dermatology) shows that niacinamide reduces hyperpigmentation by inhibiting melanosome transfer. Research in the Journal of Cosmetic and Laser Therapy shows that 5% niacinamide reduces sebum production and improves pore appearance in oily skin. A study in the International Journal of Cosmetic Science found that niacinamide at 2-5% strengthens the skin barrier by increasing ceramide and free fatty acid levels in the stratum corneum.

Combining fermented filtrate with niacinamide creates a synergistic formulation: the nutrient-rich ferment optimizes how skin receives the niacinamide, while the niacinamide targets specific concerns (pigmentation, pore size, barrier function) that the broader ferment supports.

Adenosine acts as a supporting active and is a Korean MFDS-recognized anti-wrinkle functional ingredient. Research shows topical adenosine promotes collagen synthesis and increases skin elasticity, adding anti-aging benefits to this brightening and refining formula.

Dermatologist Perspective

Dermatologists note that 5% niacinamide is a versatile, well-tolerated over-the-counter active that addresses pigmentation, barrier function, and sebum regulation at once. Board-certified dermatologists value the minimal, irritant-free formulation, making this essence suitable for sensitive skin. While the galactomyces base has less independent evidence than niacinamide, dermatologists view it as a reasonable, nutrient-rich complement to the proven niacinamide. Because it lacks potential irritants, dermatologists can recommend this product without caveats regarding fragrance or alcohol sensitivity.

How to use

After cleansing (and toning if you use a toner), put one dropperful in your palm. Pat it onto your face and neck. Wait 30-60 seconds for absorption before your next step. Use morning and evening. You can layer it—apply two layers for more hydration and active ingredient delivery. Follow with a serum, moisturizer, and sunscreen (AM).

Value assessment

At about $18 for 60 ml, this essence costs much less than luxury galactomyces products like SK-II Facial Treatment Essence ($100+ for 75 ml). Purito includes 5% niacinamide, which SK-II Facial Treatment Essence lacks, and uses 15 ingredients instead of dozens. The active ingredient concentration per dollar offers high value, but the small bottle size requires frequent repurchasing.

Who should buy

This lightweight, minimal-ingredient brightening essence fits into any existing routine. It works for K-beauty enthusiasts, niacinamide lovers, and people with oily or combination skin facing dullness and enlarged pores. It also suits anyone with ingredient sensitivities needing a clean, irritant-free treatment step.

Who should skip

Slow results may frustrate users seeking immediate, visible changes. People with documented yeast or fungal sensitivities must patch test carefully. Very dry skin types needing thick, emollient textures will find this too lightweight to use without a substantial moisturizer on top.

08 · Behind the formula

The backstory.

The Galacto Niacin 97 was one of Purito's original products when the brand launched in 2017, embodying the brand's philosophy that effective skincare does not require lengthy ingredient lists. The '97' in the name refers to the combined 97% concentration of galactomyces ferment filtrate (92%) and niacinamide (5%), with only 3% of the formula dedicated to functional ingredients like preservatives and stabilizers.

About Purito

Emerging Brand (2–5 years)

Purito launched in 2017 as a clean K-beauty brand using safe, minimal ingredient lists. The brand rebranded to Purito Seoul in 2023 after a 2020 sunscreen SPF controversy and now uses stricter formulation and testing standards. The Galacto Niacin 97 has been a cornerstone product since its launch.

09 · Setting the record straight

Common myths.

Myth

Galactomyces ferment is yeast and everyone with fungal acne must avoid it.

Reality

Galactomyces ferment filtrate comes from filtered yeast fermentation; filtration removes the yeast itself. The filtrate has metabolites like amino acids, vitamins, and minerals but no live yeast organisms. Some people with Malassezia sensitivity may still react, so patch testing is recommended.

Myth

Essences are just expensive water and don't do anything.

Reality

This essence has 92% galactomyces ferment filtrate and 5% niacinamide. These active, well-studied ingredients use meaningful concentrations. The watery texture absorbs fast and layers easily, but the active content matches dedicated serums.

10 · Common questions

FAQ.

Can I use Purito Galacto Niacin 97 with retinol?

The 5% niacinamide in this essence pairs well with retinol. Niacinamide buffers retinol irritation without reducing its efficacy. Apply this essence first, let it absorb, then use your retinol product.

What does galactomyces ferment filtrate do for skin?

Galactomyces ferment filtrate comes from fermenting galactomyces yeast and filtering out the organisms. This process leaves a liquid with amino acids, vitamins, minerals, and organic acids. At a 92% concentration, this essence brightens skin tone, refines texture, supports the moisture barrier, and creates an optimal environment for the niacinamide to work.

How is Purito Galacto Niacin 97 different from SK-II Facial Treatment Essence?

Both use galactomyces ferment filtrate (marketed as Pitera by SK-II). The differences: Purito adds 5% niacinamide to brighten skin and control pores, uses 15 ingredients compared to SK-II's longer list, is fragrance-free and vegan, and costs much less. SK-II has more market history and proprietary fermentation claims.

When should I apply Purito Galacto Niacin 97 in my routine?

Apply after cleansing and toning, before heavier serums and moisturizers. The watery texture absorbs rapidly on clean skin. Pat it gently into the skin instead of rubbing. Follow with your next treatment step or moisturizer.
