Are drugstore skincare products as effective as luxury brands?

Many drugstore skincare products contain the same or equivalent active ingredients as their luxury counterparts at a fraction of the cost. Products like CeraVe ceramide moisturizers, Paula's Choice BHA exfoliants, and The Ordinary retinol serums have strong clinical support. Price often reflects packaging, fragrance, and brand positioning rather than ingredient efficacy. Focus on the active ingredients and their concentrations rather than brand prestige.
