What retinal does for your skin

Retinal · Retinaldehyde · Vitamin A aldehyde

TextureEvennessClarity

Retinal (retinaldehyde) is retinol's faster sibling. It's one step closer to the active form of vitamin A, so skin often sees the look of results a little sooner. In cosmetic terms it smooths and refines. Same night-active rules apply, it just tends to move quicker.

What Retinal is

Retinal is a vitamin A active that sits one step ahead of retinol on the path to the active form. That's why people often notice a smoother, more refined look a bit sooner. It's less common on drugstore shelves, so you'll usually find it in more specialist brands.
