Bifidobacterium Ferment Lysate: Unlocking the Microbial Key to Skin Repair and Anti-Ageing

In the field of cosmetic ingredients, bifidobacterium ferment filtrate stands out as a core component in high-end skincare products due to its dual efficacy of ‘microecological repair + cellular-level anti-ageing.’ This active filtrate, obtained through bifidobacterium fermentation and centrifugal extraction, contains over 1,000 small-molecule nutrients that activate the skin's self-repair mechanisms at their source.

Core Components and Mechanism of Action

Bifidobacterium ferment filtrate is rich in four major categories of active substances:

- DNA repair factors: Contains base repair enzymes (such as AP endonucleases), which can eliminate UVB-induced DNA damage (reducing CPD photoproducts by 63%), thereby slowing photoaging at the genetic level;

- Prebiotic Complex: Short-chain fatty acids (SCFAs) and beta-glucans regulate skin microbiota balance, increasing the abundance of beneficial bacteria (such as Lactobacillus) by 41% and inhibiting inflammatory responses;

- Antioxidant stress components: Glutathione (GSH) and pyrroloquinoline quinone (PQQ), with free radical scavenging capacity 8 times that of vitamin C, increasing fibroblast activity by 58%;

- Nutritional empowering factors: B vitamins and amino acids promote keratinocyte metabolism, with experiments showing that the cell turnover cycle is shortened to 21 days (normally 28 days).

Multi-dimensional efficacy verification

Clinical data shows that when using an essence containing 10% bifidobacteria extract continuously for 28 days:

- Repairing power: Redness after laser surgery subsides 3 days faster, and barrier function (TEWL) recovery speed increases by 52%;

- Anti-ageing efficacy: Collagen density increased by 29%, eye area fine lines reduced by 18%, and skin elasticity improved by 34%;

- Brightening efficacy: Melanin synthesis inhibition rate reached 47%, skin tone evenness improved by 25%, suitable for night owl skin and early ageing skin care.
