Hydroxypinacolone Retinoate (HPR) is an ester of retinoic acid that binds directly to retinoid receptors without conversion, offering anti-aging and skin-renewal benefits. It is generally considered gentler than traditional retinoids while remaining biologically active.
Retinal (retinaldehyde) is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover, collagen synthesis, and improvement of fine lines, uneven tone, and acne. It is generally considered more potent than retinol but better tolerated than prescription retinoic acid.
