Galactomyces Skincare: How to Combine with AHA, BHA, Retinoids, Vitamin C

Galactomyces: How to Combine it With Other Skincare Ingredients

Galactomyces ferment filtrate has become a popular ingredient in many Asian beauty products. This fermented yeast extract derived from sake helps brighten, hydrate, and smoothen the skin.

However, galactomyces may cause irritation or render other ingredients ineffective if mixed improperly. Learning which ingredients to avoid combining with galactomyces is key to building a compatible skincare routine.

What is Galactomyces Ferment Filtrate?

Galactomyces ferment filtrate is a type of fermented yeast extract made by filtrating and refining the sake kasu (lees) byproduct of rice wine fermentation.

It contains metabolites, saccharides, amino acids, vitamins, and minerals that nourish the skin. Galactomyces is touted to have these benefits:

• Brightens and evens skintone
• Hydrates and improves moisture retention
• Soothes inflammation and sensitivity
• Boosts radiance for a glowing complexion

Galactomyces is found in many popular Asian skincare products, especially Korean essence and serum formulations.

How Does Galactomyces Work in Skincare?

The mechanisms behind galactomyces aren't fully proven. But research suggests some ways it may improve skin:

• Increases hyaluronic acid production for better hydration
• Brightens by inhibiting melanin synthesis
• Promotes cell turnover and regeneration
• Reduces tyrosinase enzyme activity to control pigmentation
• Provides antioxidants to neutralize free radical damage

Thanks to these actions, galactomyces makes an effective ingredient for brightening skincare treatments.

Who is Galactomyces Best For?

Those with the following skin types and concerns can benefit most from using galactomyces-containing products:

• Dull, uneven skintone
• Hyperpigmentation and dark spots
• Oily, acne-prone skin
• Lackluster, tired-looking skin
• Signs of aging like fine lines and wrinkles
• Dehydrated skin lacking moisture

Ingredients to Avoid Mixing with Galactomyces

While galactomyces is suitable for most skin types, there are a few ingredients it may react poorly with. Avoid layering or using products simultaneously that contain galactomyces plus:

1. Acids (AHA, BHA)

Alpha hydroxy acids like glycolic acid and beta hydroxy acids like salicylic acid can irritate skin when combined with galactomyces. The fermented yeast extract has a low pH which can make acids feel harsher.

If using both, apply acids and galactomyces products at different times of day and don't layer them directly. Or alternate using them each day.

2. Retinoids

Retinoids can destabilize and inactivate galactomyces, stopping the ingredient from working effectively. It's best not to use them together.

Apply your galactomyces serum in the morning or during the day. Use retinoids like retinol or tretinoin at night instead.

3. Vitamin C

Like retinoids, vitamin C can also deactivate galactomyces to some degree, so its best not to combine them.

You can either use your vitamin C serum in the AM and galactomyces PM, or alternate days using them.

4. Niacinamide

Niacinamide reacts with galactomyces to form niacin, which causes flushing and redness in some people. Definitely avoid layering these two.

Use your niacinamide and galactomyces products at different times of day to prevent any reaction.

5. Benzoyl Peroxide

The peroxide component can oxidize and destabilize galactomyces, making it ineffective. Avoid combining benzoyl peroxide spot treatments or washes with galactomyces.

6. Heavy Oils and Creams

The lightweight, watery texture of galactomyces doesn't pair well with thicker oils and creams. The heavier product can block proper absorption of the fermented filtrate.

Opt for gel moisturizers if using a galactomyces serum, or layer the products thinnest to thickest.

How to Safely Use Galactomyces

You can safely reap the benefits of galactomyces in your routine. Just follow these tips:

• Patch test new galactomyces products first
• Use only 1 galactomyces product in your routine at a time
• Apply galactomyces early in your routine after cleansing
• Don't use direct acids, retinoids, or vitamin C with galactomyces
• Use niacinamide and benzoyl peroxide separately
• Opt for gel textures with galactomyces over heavy creams
• Watch for any irritation or flushing reactions

How to Use Galactomyces for Best Results

Follow these tips to incorporate galactomyces effectively into your skincare routine:

Select the Right Format

Look for galactomyces in lightweight serums, boosters, or essences designed to be layered under moisturizer.

Apply After Cleansing

Use your galactomyces product after cleansing when skin is fresh and can readily absorb the ingredient.

Use 1-2 Drops if Concentrated

For galactomyces concentrates, you only need a couple drops massaged evenly over the face and neck.

Follow With Gel Moisturizer

Pair galactomyces with a lightweight, water-based gel moisturizer to prevent clogged pores.

Use AM and PM

Galactomyces is gentle enough for twice daily use for optimal brightening over time.

Give it 4-6 Weeks

It takes consistent use to see the cumulative brightening, smoothing, hydrating benefits of galactomyces.
