Retinaldehyde
Product Introduction
Retinaldehyde can be called retinal or all-trans-retinal. It is the strongest version of vitamin A and a reletively new active ingredient for anti-ageing. Retinaldehyde is a type of retinoid. Retinoids are derived from vitamin A and help support natural collagen production for smoother, younger-looking skin. Vitamin A actually isn’t produced by our body naturally, which means the only way to get it is through food, supplements or topical skin care.

Both Retinaldehyde and Retinol have to be first converted by skin enzymes to the only active form of Retinoic Acid before working. The difference is that while retinol needs two steps to convert, retinal needs only one. That can make it faster in its conversion to retinoic acid..
Retinyl Palmitate → Retinol -- Retinaldehyde → Retinoic Acid (Tretinoin)

Retinaldehyde has been shown to improve the feel of firmness and elasticity, and reduce the appearance of fine lines, wrinkles and rough skin. It is also often tolerated than Retinoic Acid, making it an attractive option for those with sensitive or delicate skin.
