Did you know that galactomyces packs all the good stuff to protect, hydrate, and brighten your skin? Are you struggling with a dehydrated complexion? Uneven tone? Or excess sebum and acne? Then galactomyces could be the gentle answer to your skin problems.
What are galactomyces?
Galactomyces, also known as Pitera or galactomyces ferment filtrate, is a fungus that comes from the fermentation process of Japanese sake. As it ferments, galactomyces breaks down and creates stuff your skin will love. We’re talking about antioxidants, amino acids, minerals, vitamins, and yeast peptides, which are all necessary to maintain healthy skin.
So how does galactomyces work? For one, it contains a whole host of amino acids that hydrate your skin. Galactomyces also regulate sebum production to make your skin less oily and might as well diminish dark patches. And since it’s rich in antioxidants, galactomyces protect your skin from daily stressors like UV radiation and pollutants.
Galactomyces benefits for skin
- Protects the skin: Galactomyces is a rich source of antioxidants. Antioxidants are natural skin protectors. They neutralize free radicals and reduce cellular damage caused by UV exposure. Besides, galactomyces has been found to restore the proteins that maintain skin barrier function.
- Moisturizes: Galactomyces is a natural moisturizer that works to restore hydration to dry skin. It promotes the production of hyaluronic acid, which is a molecule found naturally in our skin that retains moisture.
- Brightens: As a brightening agent, galactomyces inhibits melanin, the pigment that darkens skin tone and causes dark spots. For the record, in a 2014 study, galactomyces diminished the appearance of dark spots and reduced melanin production by 60%, being effective in treating melasma and hyperpigmentation.
- Softens skin texture and soothes redness: A recent study on Japanese women found that applying galactomyces twice a day for four weeks can soften rough skin and soothe redness. A boom for eczema- and rosacea-prone skin.
- Regulates sebum production and heals acne: Galactomyces can balance sebum production and reduce acne breakouts. For reference, an essence containing 97% of galactomyces ferment filtrate was found to reduce the number of open pores by 15.66%, blackheads by 21.84%, sebum by 64.17%, and acne by 9.59%.
Is it safe?
Galactomyces is generally safe to use. However, just like other skincare ingredients, galactomyces can cause mild adverse reactions in some people with certain skin sensitivities or conditions.
We mentioned that galactomyces is a fungus. Therefore, if you suffer from fungal acne, this ingredient is not for you. One of the side effects of galactomyces is that it can make fungal acne worse by making the skin more itchy. While galactomyces can heal acne breakouts and acne scars, fungal acne is a different case. It is difficult to determine if your acne is fungal or not because they are almost the same in appearance. So if you’re not sure, it’s ideal to consult your dermatologist for professional advice.
How to use galactomyces
You’ll see galactomyces in a variety of skincare products, especially brightening, anti-aging, and pore-minimizing products. For the best results, use it every morning. If you have dry or combination skin, serums of thicker consistencies should work better. On the other hand, if you have oily skin, serums of thinner consistencies will do fine.
Who should use galactomyces
Unless you have fungal acne, you can use skincare products with galactomyces. Galactomyces is especially effective if you have dry and dull skin, deal with whiteheads, blackheads, or large pores, or are concerned about UV damage or uneven skin tone with dark patches.
What you can mix with galactomyces
Galactomyces is a gentle and skin-friendly ingredient, so mixing it with other skincare actives shouldn’t be a problem. Even strong ingredients such as retinol, AHAs, BHAs, and vitamin C can work with galactomyces. Galactomyces also pairs quite well with niacinamide, hyaluronic acid, and snail mucin to relieve skin dryness and roughness. For skin discoloration and post-acne blemishes, studies found that using galactomyces with tranexamic acid, niacinamide, and hydroquinone is very effective at brightening the skin and reducing dark patches.
