You might have observed the prevalence of fermented ingredients in Korean beauty products. Often, the labels mention components like "galactomyces ferment filtrate", "bifida ferment lysate", or "saccharomyces ferment filtrate".
While in daily life we commonly associate fermentation with foods like yogurt, sauerkraut, cheese, beer, and wine, the process is also essential for the production and preservation of these items. Essentially, fermentation refers to a specialized process where organic materials transform under anaerobic conditions (without oxygen) through the action of fungi and bacteria. The products derived from this process are notably compatible with the skin and digestive system. They are naturally preserved, maintain a low pH, and also exhibit antimicrobial and antifungal properties (targeting bacteria and fungi).
Cosmetic Application
Given the myriad benefits for skin and overall health, the use of fermentation in cosmetic ingredients has seen a rise. Natural substances like yeast, bamboo, rice, or soy undergo transformation through fermentation in an oxygen-free environment. The metabolic activities of microorganisms during fermentation yield health-enhancing compounds such as amino acids, vitamins, lactic acids, polysaccharides, and beta glucan. Furthermore, fermentation breaks down an ingredient into smaller molecules and proteins, enhancing its bio-availability — this means the skin can absorb these compounds more effectively. The fermentation process also improves the compatibility of many base ingredients by converting potential allergenic proteins into non-allergenic forms. Additionally, most fermented ingredients generally have a lower pH, which inhibits bacterial growth, thereby naturally prolonging the product's shelf life.
Popular Fermented Ingredients
Several fermented ingredients have gained prominence in Korean cosmetics due to their advantageous properties and are thus frequently incorporated into these products.
Fermented Lysates
Derived through the fermentation process in a specialized nutrient solution, these probiotic actives offer various skin benefits. For instance, Lactobacillus Ferment Lysate promotes skin repair by enhancing cell renewal, boosting collagen production, and augmenting skin hydration. Consequently, it refines the skin texture, tightens it, reduces wrinkles, and renews skin cells. The Neogen Real Ferment Micro Essence, as an example, incorporates Bifida Ferment Lysate, Saccharomyces Ferment Filtrate, and Rice Ferment Filtrate in its formula.
Fermented Soy
These active components are readily absorbed by the skin. Studies have shown that they bolster the skin barrier, enhance microcirculation, and provide hydration. Additionally, they offer anti-inflammatory and skin-soothing effects. The Purito Fermented Complex 94 Boosting Essence is a notable product in this category. It contains Lactobacillus/Rice Ferment, Bifida Ferment Lysate, Saccharomyces/Imperata Cylindrica Root Ferment Extract, and Lactobacillus/Soybean Ferment Extract — encompassing a total of four distinct fermented ingredients.
Fermented Algae, Rice, and Milk Products
These components are abundant in sugar molecules that hydrate the skin. For instance, lactic acid derived from lactose milk sugar can gently exfoliate the skin, fostering a uniform skin tone. Fermented black rice stands out as a crucial component in various Haruharu Wonder offerings, including the Haruharu Black Rice Serum and Haruharu Black Rice Toner.
Fermented Yeast
Fermented yeast generates amino acids and peptides instrumental in cell renewal. Notable products containing this ingredient include the IUNIK Rose Galactomyces Synergy Serum and iUNIK Beta Glucan Power Moisture Serum.
Fermented Tea
Black, green, and kombucha teas are especially enriched with antioxidants. They serve to shield the skin from free radical damage, thus thwarting premature signs of aging.
Given their numerous beneficial attributes and commendable compatibility, it's certainly advantageous to explore products infused with fermented ingredients. These compounds, acting as anti-aging boosters, intensively nurture and pamper your skin without causing irritation.
