Description
Retinaldehyde (retinal) is a synthetic form of vitamin A and a direct precursor to retinoic acid, a potent retinoid used in skincare. It is utilized for its anti-aging, acne-treating, and hyperpigmentation-reducing properties. Retinal accelerates skin cell turnover and stimulates collagen production. While effective, retinal can cause skin irritation and increased sun sensitivity. Dosage depends on product formulation, and users should start with low concentrations and use sunscreen daily.
