Galacto Niacin 97 Power Essence

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.

Formula

The Science

The two headline ingredients — galactomyces ferment filtrate and niacinamide — bring complementary evidence bases. Galactomyces ferment filtrate gained scientific attention through research on Pitera (SK-II's branded version). Studies have demonstrated that galactomyces-derived ferments contain a rich profile of amino acids, organic acids, vitamins, and minerals that improve skin texture, hydration, and radiance. A study published in the Journal of Drugs in Dermatology examined the effects of topical galactomyces ferment filtrate and found improvements in skin smoothness, wrinkle reduction, and pore appearance.

Niacinamide at 5% has one of the most robust evidence bases in cosmetic dermatology. The landmark Hakozaki et al. study (2002, British Journal of Dermatology) demonstrated that niacinamide significantly reduces hyperpigmentation by inhibiting melanosome transfer. Additional research published in the Journal of Cosmetic and Laser Therapy showed that 5% niacinamide reduces sebum production and improves pore appearance in oily skin types. A separate 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.

The combination of fermented filtrate with niacinamide creates what researchers would call a synergistic formulation: the nutrient-rich ferment optimizes the skin's receptivity to the niacinamide, while the niacinamide provides targeted action against specific concerns (pigmentation, pore size, barrier function) that the broader ferment supports.

Adenosine, included as a supporting active, has been recognized by Korean MFDS as an anti-wrinkle functional ingredient. Research shows that adenosine promotes collagen synthesis and increases skin elasticity when applied topically, adding an anti-aging dimension to the primarily brightening and refining formula.

Dermatologist Perspective

Dermatologists note that niacinamide at 5% is one of the most versatile and well-tolerated active ingredients available over the counter, addressing pigmentation, barrier function, and sebum regulation simultaneously. Board-certified dermatologists appreciate the minimal, irritant-free formulation that makes this essence suitable for patients across the sensitivity spectrum. The galactomyces base, while having a less extensive independent evidence base than niacinamide, provides a nutrient-rich vehicle that dermatologists view as a reasonable complement to the proven niacinamide. The absence of potential irritants makes this a product that dermatologists can recommend without the usual caveats about fragrance or alcohol sensitivity.

Guidance

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.

Myth vs. Reality

Myth

Galactomyces ferment is the same as yeast and should be avoided by everyone with fungal acne.

Reality

Galactomyces ferment filtrate is a filtered product of yeast fermentation — the yeast itself is removed during the filtration process. The filtrate contains beneficial metabolites (amino acids, vitamins, minerals) without live yeast organisms. That said, some individuals 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 contains 92% galactomyces ferment filtrate and 5% niacinamide — these are active, well-studied ingredients at meaningful concentrations. The watery texture enables rapid absorption and easy layering, but the active content is comparable to dedicated serums.
