Introduction
After chemical exfoliation, the stratum corneum becomes thinner; therefore, high-performance skincare products—such as toners, moisturizers, and serums—should be temporarily discontinued. The primary focus of skincare should shift to supporting and repairing the skin barrier. Simplify your routine by reducing both the number of steps and the variety of products used. Opt for hydrating, soothing toners and moisturizers, as well as masks with minimal, gentle ingredients.
In recent years, “chemical exfoliation” (commonly referred to as “acid peeling”) has grown increasingly popular. Many women believe this treatment improves skin appearance, yet they often overlook post-peel skin recovery. Key considerations are outlined below:
After chemical exfoliation, the stratum corneum becomes thinner. High-performance skincare products—such as toners, moisturizers, and serums—should be temporarily discontinued. The primary focus of post-peel skincare should be barrier repair: simplify your routine and product selection, and opt for hydrating, soothing toners and moisturizers, as well as gentle, minimally formulated masks.
If skin remains dry after using toner and moisturizer, apply a hydrating, moisture-retentive cream. Especially for dry skin types, a rich, emollient cream may be applied to the face—but avoid applying it too thickly.
Sun protection is critical following chemical exfoliation. UV radiation peaks during summer months and may exacerbate post-acne hyperpigmentation. Therefore, immediately after peeling, it is advisable to avoid sunscreen application altogether; instead, use physical sun protection measures such as umbrellas and wide-brimmed hats when outdoors. If sunscreen is necessary, opt for mineral (physical) formulations to minimize potential skin irritation.
Importantly, chemical exfoliation should always begin at a low concentration and be gradually increased. Overuse may compromise the skin barrier, triggering visible warning signs (e.g., redness, stinging, or flaking). In such cases, reduce the concentration accordingly. If even the lowest concentration causes adverse reactions on the face, discontinue chemical exfoliation entirely.
