A night-only retinaldehyde serum for fine lines and texture
Isdin Rejuvenate Retinal Smooth Anti-Aging Serum with Retinadehyde is an anti-aging night serum with retinaldehyde for skin that wants a retinoid-family ingredient for fine lines and texture. Retinaldehyde is a form of vitamin A one step closer to retinoic acid than retinol, used here at night as the active step of Isdin's Rejuvenate anti-aging line.
The texture
A fluid serum that absorbs quickly and is meant to be worn only at night, layered under a moisturiser.
Who it suits
- Fine lines and uneven texture
- Anyone already comfortable using retinoid-family ingredients
- A night-only step in an anti-aging routine
- Pairing with daily SPF, which is essential alongside any retinoid
Worth knowing before you buy: Retinaldehyde can be irritating at first use and increases sun sensitivity — introduce it gradually (a few nights a week to start) and always wear daily SPF.
