Cassatt makes one product we stock: La Pommade, a retinoid in an ointment base rather than the usual serum or lotion. The texture is the whole idea. Retinoids tend to leave skin tight and flaking, and an occlusive balm keeps it comfortable while the active does its work. It suits anyone who has tried a retinol, liked the result and disliked the feel. Start two or three nights a week and wear sunscreen every morning.
