What Studied

Regulatory consumer information about alpha hydroxy acids in cosmetic products, including expected uses, sun-sensitivity considerations, and labeling context.

Why It Matters

This source anchors the glycolic-acid discussion in a realistic frame: cosmetic acid use is reasonable, but daily sunscreen and modest frequency are part of safe at-home practice rather than optional add-ons.
