Lactobacillus … Ferment

This ingredient is a fermented complex derived from soybean extract, created using Lactobacillus and Streptococcus thermophilus cultures. Fermentation breaks down soybean compounds into smaller, more bioavailable molecules, which can penetrate the skin more effectively than unfermented soybean alone.In skincare formulations, it functions primarily as a skin and hair conditioning agent, helping to soften and smooth the skin's surface. It also acts as an emollient, meaning it helps seal moisture into the skin by forming a protective layer.

Fermentation creates a gentler, more refined version of soybean extract by breaking down larger molecular structures into smaller peptides and amino acids. This makes the ingredient easier for skin to absorb and utilise.Once applied, the conditioning agents work by coating the skin with a protective film that reduces transepidermal water loss (TEWL), helping to maintain hydration. The emollient properties improve skin feel and suppleness without leaving an occlusive residue.

This ingredient is typically incorporated into creams, serums, and moisturisers as part of a multi-ingredient formula rather than used in isolation. It works well alongside other hydrating and conditioning ingredients. There is no specific upper limit on daily use; it can be incorporated into both morning and evening skincare routines as tolerated.

Generally well-tolerated across skin types. Fermented ingredients may occasionally cause sensitivity in those with soy allergies, though the fermentation process may reduce allergenicity.
