Hydrate from Within
You may not know this but live Lactobacillus probiotics on (and in) skin can produce the coveted skincare ingredient Hyaluronic Acid. Right there in the stratum corneum of your skin they pump out super-hydrating molecules that plump your skin and keep it deep-moisturised.
Hyaluronic acid is popular in skincare for good reason. Apart from its hydrating superpowers, Hyaluronic Acid also fights inflammation and speeds up healing.
Lactobacillus species have also been shown to improve barrier function in skin. They improve the cell binding (by T-junctions) in the stratum granulosum, which slows down the rate of moisture loss (TEWL / trans epidermal water loss) resulting in a plumper, healthier-looking skin.
