celimax VITA-A Retinol Shot Tightening Serum — Retinol Firming Serum, 30 ml

A silky serum, absorbed within seconds, without the sticky feel often associated with retinol serums.

Why we love it

Formulated with 0.1% retinol and a 9-peptide complex, two families of ingredients recognized for their action on wrinkles and firmness — retinol requires two steps of enzymatic conversion to reach its active form, which explains a more gradual action than retinal. Like all retinoids, it should be avoided during pregnancy or breastfeeding as a class precaution. The first retinol serum in the Glasskin Beauty selection, designed for mature skin seeking firmness and refined texture. Signal peptides have the strongest clinical grounding in their family, which makes them a coherent complement to retinol rather than a mere label claim.

How to use it

Apply in the evening only, on dry skin, avoiding nights when you use an AHA/BHA, pure vitamin C or benzoyl peroxide — these combinations cancel each other out or irritate the skin rather than reinforcing it. Start with two evenings a week, then increase as tolerated. Sun protection is essential the following morning, as retinol increases photosensitivity.

Who it's for

Mature skin or skin showing its first fine lines, skin looking for a smoother texture and renewed bounce, excluding pregnancy and breastfeeding. Very reactive skin should start with a low-dose retinol cream instead. Discover our retinol selection to go further in anti-aging care, and our targeted signs of aging products.
