HiCA Retinoid Serum Hydroxypinacolone Retinoate 0.1% 30ml is a retinol serum from Japanese brand HiCA. Its core active is 0.1% hydroxypinacolone retinoate (HPR), a novel retinoid ester that acts directly on the skin without conversion, working quickly with less irritation — co-developed with dermatologists with Japanese skin in mind. The formula also pairs encapsulated retinol, 2% niacinamide and two peptides to visibly plump, firm and smooth.

Five human-type ceramides, panthenol, allantoin and CICA (centella asiatica extract) soothe and protect, while hydrolysed hyaluronic acid keeps skin hydrated. Alcohol-free and fragrance-free, patch-tested for sensitive skin. Use at night as the first step after cleansing (avoid the eye area), then follow with lotion or cream. If new to retinoids, start every 2–3 days for the first two weeks and build up gradually; always wear sunscreen during the day.
