Retinaldehyde

What is it?

Retinaldehyde is a vitamin A derivative one conversion step closer to active retinoic acid than retinol, used in skincare for anti-aging benefits with a generally better tolerability profile than stronger retinoids.

What does it do?

Commonly used to help improve the appearance of photoaged skin, fine lines and texture with fewer adverse effects than more aggressive treatments. A randomized controlled study found a retinaldehyde-based cream performed comparably to glycolic acid peel sessions on wrinkle and texture measures, with 12x fewer adverse events, and a separate RCT found a retinaldehyde-containing antioxidant blend improved in situ antioxidant activity in photoaged skin.
