Retinaldehyde for Sun Damage (Photoaging)

Works like retinol but converts faster on your skin, so results come sooner with less irritation.

Why it works for Sun Damage (Photoaging)

A retinoid just one step away from the active form, so your skin converts it more directly than retinol. Trials at 0.05 to 0.1 percent show it improves wrinkle depth, texture, and uneven color from the sun about as well as tretinoin, but it is gentler. A good step up from retinol when you want something stronger.

How Retinaldehyde works

One step from retinoic acid; converts faster than retinol with comparable cell-turnover effect.
