The main difference is in strength, purpose, and frequency of use. A daily glycolic acid toner typically contains a much lower concentration (often 5-10% or less) and is formulated to be part of a regular cleansing routine, providing mild, consistent exfoliation. This INOPHARM peel, at 20% glycolic acid, is a more intensive treatment designed for periodic, targeted use—often once a week or every other week—to deliver a stronger exfoliating effect. Its purpose is to more effectively loosen the bonds between dead skin cells, leading to a more noticeable improvement in skin texture and brightness after use. Because of its higher potency, it is not meant for daily application and requires more cautious introduction, especially for those new to acids.
In practice, you would apply the peel to clean, dry skin, leave it on for the recommended time (starting with a shorter duration), then rinse it off completely. This is unlike a toner, which is usually left on the skin. Following the peel with a simple, soothing moisturizer is important to help counteract any temporary tightness and support the skin barrier.
