Focus on the total exfoliation routine
If you already use an AHA, BHA, retinoid cosmetic, or peel, a mandelic acid product may add overlap. Compare what you currently use with the candidate’s intended frequency and other ingredients. Products that feature mandelic acid can include combinations, so the named ingredient is not a complete description of the formula. A spot-positioned product may have a different application area from a full-face serum. Check the directions and any sensitivity cautions. Avoid choosing by a “best for sensitive skin” slogan alone; suitability depends on formulation and individual response. One clearly assigned exfoliation step is easier to use and evaluate than several products purchased for the same concern.
