This peel uses lactic acid, an alpha-hydroxy acid (AHA), for chemical exfoliation, which works by loosening the bonds between older skin cells on the surface so they shed more easily. This process happens at a cellular level without the abrasive, scrub-like friction of physical exfoliants (like sugar scrubs or brushes). Chemical exfoliation is often better suited for improving overall skin texture, visual tone, and the look of post-blemish marks or flaky areas, as it can work more evenly across the skin's surface.
Physical scrubs rely on manual abrasion to physically buff away dead cells. While they can provide an immediate feeling of smoothness, they may not be as effective for gradual surface refinement and can sometimes cause micro-tears or irritation, especially on sensitive or inflamed skin. This lactic acid formula, with added glycerin for moisture-binding, aims to refine texture and support brighter-looking skin while minimizing the potential for the tight, dry feeling that can come with some acid use. It's a leave-on or short-contact treatment designed for integration into an evening routine focused on gradual resurfacing.
