Founder & Medical Director at New York Cosmetic Skin & Laser Surgery Center

I'm a board-certified dermatologist in New York. In my clinic, fermented lysates and filtrates can be helpful for red, reactive skin. I found a study of 52 adults using a lotion with a 3% fermented culture blend twice daily for 30 days. Mean redness dropped from 33.98 to 29.3. The BoSS sensitive-skin score fell from 23.29 to 17.63, and many reported less itching and tingling. Patch test behind the ear. Start two nights a week, then build. Apply after cleansing, then a plain moisturizer. Keep acids or retinoids on different nights at first. The same report found a fermented Lactobacillus supernatant inhibited tyrosinase 72.1% in vitro, which fits the subtle brightening I sometimes see. I can send written answers within four days.
Skincare using fermented ingredients isn't merely hype; there's actually sound science behind it, making it truly effective in caring for your skin. As fermentation happens, bigger molecules of the fermented substance become smaller, making it easier for it to be absorbed into the skin, allowing it to better interact with the skin's properties in an effective manner. Fermentation also ensures that antioxidant properties in products get better leverage in shielding your skin from environmental elements. Fermented extracts also promote balance in having healthy skin microbiome; this assists in fighting inflammation in your skin, making it suitable for people who have sensitive skin. Fermented ingredients in products aren't magic; rather, it enhances other compounds, making it most effective when used in an overall regimen suitable to the type of skin you have.
Hello Vivian Chung, Can you share your questions here or at my email drkhankanwal8@gmail.com: My profile Shamsa Kanwal, M.D., is a board-certified Dermatologist with over 10 years of clinical experience. She currently practices as a Consultant Dermatologist at https://www.myhsteam.com/(USA) Profile link: https://www.myhsteam.com/writers/6841af58b9dc999e3d0d99e7 Fermented ingredients are usually plant extracts or microbes that have been processed to create smaller byproducts like amino acids and antioxidants, which can feel more hydrating, soothing and barrier supportive than the non-fermented version. The main benefit I see is improved comfort and glow in people with dehydration or mild sensitivity, but they are not a cure for acne, pigment or wrinkles on their own. Best practice is to add one fermented product at a time, start 2 to 3 times weekly, apply after cleansing before moisturizer and patch test for 48 hours if you have reactive skin.

I work as a Vice President and Lead Clinical Director in Texas Academy of Medical Aesthetics and collaborate with dermatologists and advanced aesthetic providers in ingredient safety, skin physiology, and post treatment care areas. Fermented ingredients are undergoing hype because fermentation breaks down complex compounds into smaller, more readily absorbed by the skin, compounds. This can result in better tolerance and skin barrier support, which is highly essential to the patients whose skin is sensitive or damaged. Fermented ingredients as yeast or botanical extracts can be effective in clinical practice to enhance hydration, skin comfort and texture in general. The most absolute is to introduce these skincare products gradually and apply a single formula at a time and the standard procedure is patch testing. The ingredients tend to produce the best effects when they are used with barrier-supporting staples such as ceramides and niacinamide. Fermented skincare has the best potential to be a useful addition to evidence, rather than a replacement of current dermatologic care, when used correctly.
