Think Nature

Galactomyces is a type of yeast, and galactomyces filtrate is the liquid produced by fermenting it. The filtrate is dense with amino acids, vitamins, and organic acids that build up during the fermentation process. In skincare, it is primarily known for two effects: brightening uneven skin tone and strengthening the skin barrier. The brightening action comes from the inhibition of melanin synthesis - the same mechanism that made fermented yeast extract famous after Japanese sake brewery workers were observed to have exceptionally smooth hands. Barrier support comes from the amino acids and saccharides that reinforce the outer layers of the epidermis. Think Nature uses galactomyces filtrate as the cornerstone active in both their essence and serum, which is why both products share a similar functional profile while differing in texture and concentration.

The Think Nature Galactomyces Essence (130ml) and Galactomyces Serum (50ml) sit at different steps in a routine and serve different purposes even though they share the same hero ingredient. The essence is the lighter, higher-volume product meant for broader coverage - after cleansing and toning, you press or pat the essence across the full face to prep the skin and deliver an initial concentration of galactomyces filtrate. The serum is the more targeted, more concentrated step. At 50ml it is the compact, higher-potency application that you layer on specific areas of concern - uneven patches, dull zones, or areas where you want more intensive barrier repair. Many routines include both: the essence first for full-face hydration prep, then the serum targeted where needed. If you are starting with one product, the essence is a better introduction because of its lighter texture and gentler concentration.

The brightening effect of galactomyces filtrate is gradual rather than immediate - this is not an AHA/BHA exfoliation product. What you are getting is a consistent suppression of excess melanin production alongside improved skin cell turnover supported by the amino acids in the filtrate. Post-inflammatory hyperpigmentation from old blemishes and general dullness caused by a sluggish skin surface are the primary targets. Most users see a noticeable improvement in luminosity after four to six weeks of daily use. The Think Nature Galactomyces Essence is particularly effective as a daily brightening step because of its watery, fast-absorbing texture - it does not sit on the skin or leave a heavy layer that disrupts subsequent steps.

In a Korean skincare routine, essences come after toner and before serums. The Think Nature Galactomyces Essence belongs in that gap: cleanse, tone if applicable, apply the essence across the full face, then layer the serum on targeted areas if you are using both. The essence prepares the skin to absorb subsequent products more efficiently - a function sometimes called the "toner effect" in Korean beauty. The serum follows the essence and precedes heavier moisturizers or face oils. Both the essence and serum are suitable for morning and evening use. In the morning routine, they sit under SPF without causing pilling when followed by a non-silicone sunscreen.

Galactomyces filtrate is well-tolerated across skin types, but it delivers the most visible results on two groups. First: oily and combination skin that deals with post-blemish marks and uneven tone. The galactomyces filtrate regulates sebum-related imbalances and speeds up the fading of marks without drying the skin out. Second: dull or dehydrated skin that looks flat and lacks luminosity. The amino acids in the filtrate add genuine hydration depth, and the skin tends to look more plump and clear with regular use. Dry skin types can use the products but may want to pair them with a richer moisturizer to compensate for the relatively lightweight textures. Sensitive skin types generally tolerate galactomyces well, though a patch test is sensible if you are new to fermented actives.

The Think Nature Essential Oil Conditioner in Spearmint (200ml) extends the brand's approach to natural actives into hair care. Spearmint essential oil is used in hair care primarily for its scalp-stimulating properties - it creates a light cooling sensation on the scalp that many users associate with a cleaner, refreshed feeling after washing. The conditioner format means it is applied post-shampoo and rinsed out, delivering conditioning benefits alongside the spearmint active. It is a distinct product from the galactomyces facial line and is relevant for customers who prefer essential-oil-led, plant-active hair care rather than silicone-heavy conditioning. The 200ml size is a standard single-bottle supply for approximately one to two months of regular use.

Think Nature's galactomyces essence and serum are compatible with most actives used in a typical routine. They work well alongside niacinamide, which also targets hyperpigmentation through a complementary pathway. Layering galactomyces under hyaluronic acid serums or moisturizers is straightforward - the light texture absorbs before the heavier step lands. With retinoids and AHA/BHA acids, the pairing is generally fine on alternating days or in separate AM/PM slots, but direct same-layer mixing with high-concentration AHAs can sometimes destabilize the amino acid content of fermented products. If you use a Vitamin C serum in the morning, apply it before or after the galactomyces essence depending on which layer your skin absorbs better - both are water-based and low-pH, so order matters less than with oil-based actives.
