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.
Retinaldehyde (retinal) is a vitamin A derivative that is converted to retinoic acid in the skin, used to promote cell turnover, improve photoaging, and reduce acne. It is considered more potent than retinol but generally better tolerated than prescription retinoic acid.
