“[People with dry skin should] look for serums that are for sensitive skin and have hydrating ingredients, such as hyaluronic acid, ceramides, and squalene,” says New York City-based dermatologist Dendy Engelman, who recommends SkinMedica’s HA5 Rejuvenating Hydrator to patients.

“It has a gel-like consistency and five different types of hyaluronic acids, plus a SkinMedica proprietary ingredient for sustained hydration throughout the day.”
