Glass Skin Glow

Galactomyces ferment delivers vitamins, amino acids, and minerals for a luminous, translucent complexion.

Deep Hydration

Increases skin's natural moisturizing factors (NMF) and filaggrin production for long-lasting hydration.

Brightening Power

Helps reduce melanin production to fade dark spots, hyperpigmentation, and even out skin tone.

Barrier Strengthening

Activates aryl hydrocarbon receptors (AhR) to upregulate epidermal barrier proteins for healthier skin.

Antioxidant Protection

Protects against oxidative stress and UV-induced inflammation to prevent premature aging.

Sebum Control

Helps regulate oil production and keratin for a balanced, shine-free complexion without clogging pores.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding Safe

Contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Galactomyces is considered safe for use during pregnancy and breastfeeding by dermatologists.

Not Fungal Acne Safe

Galactomyces ferment filtrate activates the Aryl Hydrocarbon Receptor (AhR), which may worsen malassezia folliculitis (fungal acne). Avoid if prone to fungal acne.

Low Comedogenic Risk

With only 2 ingredients and no oils, fatty acids, or pore-clogging substances, this essence has minimal risk of causing breakouts.

Sensitive Skin Friendly

Free from alcohol, artificial fragrances, parabens, sulfates, and silicones. Used in postpartum care centers and medical spas in Korea.

Retinol Compatible

Can be used alongside retinol, vitamin C, and AHA/BHA. Apply this essence first, wait for absorption, then follow with actives.

Patch Test Recommended

Despite the minimal formula, some individuals may experience sensitivity to fermented ingredients. Test on a small area first.

Ingredient breakdown

INGREDIENTS

Galactomyces Ferment Filtrate 60%Proven

A nutrient-dense fermented yeast extract derived from sake brewing. Rich in vitamins (B vitamins), amino acids, minerals, peptides, and organic acids that work synergistically to transform skin. Also known as "Pitera" in SK-II products.

  • 2014 Study: Demonstrated ability to reduce skin pigmentation and inhibit melanin synthesis.
  • 2015 Study: Found to activate aryl hydrocarbon receptor (AhR) which upregulates epidermal barrier proteins.
  • Korean Research: Shown to reduce pore size, control sebum production, and eliminate blackheads.
  • P&G Study: Confirmed antioxidant properties and ability to increase hyaluronan (hyaluronic acid) production in epidermal cells.
Not recommended for those with fungal acne (malassezia folliculitis) as it may activate AhR which has been linked to fungal skin conditions.

Butylene Glycol 40%Proven

A multi-functional, colorless, syrupy liquid that serves as an excellent delivery system for the galactomyces extract while providing additional skin benefits.

  • Penetration Enhancer: Helps the galactomyces ferment absorb faster and deeper into the skin.
  • Humectant: Attracts and binds water to keep skin hydrated without heaviness.
  • Slip Agent: Creates a smooth application experience for even product distribution.
  • Solvent: Dissolves and stabilizes the galactomyces filtrate in the formula.
Generally well-tolerated by all skin types. Very rare sensitivity reactions possible in extremely reactive skin.

Frequently asked questions

FAQ

Yes, this essence is considered safe during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Galactomyces ferment filtrate is a naturally-derived yeast extract with no known risks during pregnancy. Dermatologists confirm it's suitable for expectant and nursing mothers. However, always consult your healthcare provider before introducing new skincare products during pregnancy.

No, this product is NOT fungal acne safe. Galactomyces ferment filtrate has been shown to activate the Aryl Hydrocarbon Receptor (AhR), which has been linked to malassezia yeast activity on the skin. If you have fungal acne (pityrosporum folliculitis), seborrheic dermatitis, or are prone to fungal skin conditions, this product may worsen your symptoms. Consider alternatives like snail mucin or centella-based essences instead.

Yes, this essence is compatible with most active ingredients including retinol, vitamin C, and AHA/BHA. Its gentle, hydrating formula actually helps buffer and prep skin for stronger actives. Apply the essence first after cleansing/toning, wait 1-2 minutes for absorption, then apply your actives. The galactomyces can even enhance the penetration of other products.

This essence works excellently for most skin types, especially oily, combination, sensitive, and mature skin. The lightweight watery texture absorbs quickly without leaving residue, making it ideal for oily skin. Sensitive skin benefits from the minimal, fragrance-free formula. Dry skin types can use it but may need a richer moisturizer on top. The only skin type that should avoid it is those prone to fungal acne.

Results vary by individual, but generally: Week 1 brings immediate hydration and smoother skin feel. Weeks 2-3 show improved skin texture and subtle glow. Weeks 4-6 reveal noticeable brightening and fading of dark spots. Week 8+ shows significant improvement in overall skin tone, radiance, and fine lines. For best results, use consistently twice daily (AM and PM) for at least 4-6 weeks.

Apply after cleansing and toning, before serums and moisturizers. The order is: Cleanser → Toner → This Essence → Serum → Moisturizer → Sunscreen (AM). For the Mixsoon 3-Layer Glass Skin routine, layer: Galactomyces Essence → Bifida Ferment Essence → Bean or Centella Essence. Always apply thinnest to thickest consistency products.

This essence has a comedogenic rating of approximately 1/5, meaning it has very low pore-clogging potential. With only 2 ingredients and no oils, fatty acids, or known comedogenic substances, it's highly unlikely to cause breakouts or clogged pores. The watery texture absorbs completely without leaving residue. However, those with fungal acne should still avoid it due to the fermented yeast content.

The Period After Opening (PAO) is 12 months. Once opened, use within one year for optimal freshness and efficacy. Store in a cool, dry place away from direct sunlight. If refrigerated, it can stay fresh longer and provide a cooling sensation during application. Discard if you notice any changes in color, smell, or texture.

Yes, Mixsoon Galactomyces Essence is widely considered one of the best SK-II dupes available. Both products feature Galactomyces Ferment Filtrate (Pitera) as the star ingredient. SK-II contains about 90%+ Pitera while Mixsoon has 60%, but at roughly 1/10th the price ($25 vs $185+), Mixsoon offers excellent value. Many users report similar hydrating and brightening results. SK-II may have a slight edge in radiance and pore refinement, but for most people, the price difference isn't justified.

Mixsoon's philosophy centers on minimalism and clean beauty. They believe in using only essential ingredients without unnecessary fillers that might cause skin irritation. The 2-ingredient formula (Galactomyces Ferment Filtrate 60% + Butylene Glycol 40%) allows the star ingredient to work effectively without interference from preservatives, fragrances, or other additives. This makes it ideal for sensitive skin and those who prefer transparent, straightforward skincare.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: Mixsoon Galactomyces Ferment Essence is an excellent minimalist essence that delivers on its promises of hydration, brightening, and improved skin texture. As one of the best SK-II dupes on the market at a fraction of the price, it offers incredible value for those seeking the benefits of galactomyces ferment. The ultra-simple 2-ingredient formula is perfect for sensitive skin and clean beauty enthusiasts. While it's not suitable for fungal acne sufferers and results take time to show, the overall experience is impressive. A must-try for anyone wanting to achieve that coveted Korean glass skin look without breaking the bank.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
