Medik8 Hydr8 B5 Serum

Medik8 Hydr8 B5 Serum is a hyaluronic acid serum formulated to address dehydration and fine lines. The brand positions it for dry or wrinkled skin and claims it delivers smoothing and plumping results within 24 hours. It contains hyaluronic acid, panthenol (a humectant that draws water into the skin), urea, alpha hydroxy acids, and vitamin A, along with what the brand calls Natural Moisturizing Factors.

Per the brand, this serum is silky-soft and non-sticky. The product is alcohol-free, paraben-free, fragrance-free, and phthalate-free, and carries a cruelty-free certification. The brand associates it with collagen boosting benefits, though the mechanism and evidence are not detailed in available information. Alpha hydroxy acids work as exfoliants within the skin, which can increase sun sensitivity, so daily sunscreen use is advised when using this product.
