Retinal is the oxidized form of vitamin A, which can be further converted into retinoic acid in the body and directly act on skin cells.
Since retinoic acid is the real anti-aging agent, exogenously supplemented retinol, retinal, and retinol esters will be converted into retinoic acid by enzymes on the surface of the skin, and then bind to retinoic acid receptors to exert biological activity.
Vitamin A in the human body is cleaved into two cis-retinal by the BCMO1 enzyme.

Core Advantages

Compared with other vitamin A ingredients:
Retinaldehyde has unique advantages in the vitamin A family (retinol, retinyl esters, retinoic acid):
1. High efficiency: It is closer to the active form of retinoic acid than retinol and takes effect faster.
2. Mildness: It is significantly less irritating than retinoic acid and has a wide range of applications.
3. Light stability: It is more stable than retinol and is not easily oxidized and ineffective.

What does retinal do to the skin?

Clinical evidence: Multiple studies have shown that continuous use of 0.1% retinal for 12 weeks can not only significantly reduce wrinkle depth by 20% but also improve skin elasticity.

Mechanism of action:
Promote collagen production: stimulate fibroblasts, increase the synthesis of collagen and elastin, and improve skin firmness.
Accelerate cell renewal: regulate epidermal cell differentiation, accelerate the metabolism of old keratin, and make the skin smoother and more delicate.
Regulate oil secretion: inhibit overactive sebaceous glands, reduce acne and closed comedones.
