Glycolic Acid 7% Exfoliating Toner

As listed: Glycolic Acid

The smallest alpha-hydroxy acid, it weakens corneocyte cohesion to promote surface exfoliation and, with continued use, stimulates collagen and glycosaminoglycan synthesis. It improves texture, dullness, and dark spots — but increases sun sensitivity.

A small humectant that attracts and holds water in the stratum corneum, delivered into the epidermis partly via aquaporin-3. It raises hydration, improves plasticity and desquamation, and supports barrier recovery — one of the best-evidenced moisturizing agents.
