Retinal

Retinal (retinaldehyde) is the aldehyde form of vitamin A that sits between retinol and retinoic acid in the retinoid conversion pathway, requiring only one enzymatic step to convert to the active retinoic acid versus retinol's two steps. This makes it significantly more potent than retinol (up to 11 times in some studies) while being better tolerated than prescription tretinoin, offering formulators a powerful anti-aging active with reduced irritation potential. Its encapsulated form at 10% provides enhanced stability against oxidation and light degradation while allowing for controlled release, making it particularly valuable in premium anti-aging formulations where efficacy and tolerability must be balanced.
