Introduction
After chemical exfoliation, the stratum corneum becomes thinner; thus, high-performance skincare products—such as toners, moisturizers, and serums—should be temporarily discontinued. The primary focus of skincare at this stage should be on restoring and supporting the skin barrier. Simplify your routine by using only gentle, hydrating, and soothing toners and moisturizers, along with masks containing minimal, non-irritating ingredients. If dryness persists even after applying toner and moisturizer, consider adding a hydrating and moisture-retentive face cream.
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 the critical importance of post-peel skin repair. Specific recommendations follow:
After chemical exfoliation, the stratum corneum becomes thinner. Therefore, high-performance skincare products—such as potent toners, lotions, serums, and essences—should be temporarily discontinued. The primary focus of post-peel skincare should be barrier repair: simplify your routine and product selection, and opt for gentle, hydrating, and soothing toners and moisturizers, along with masks containing minimal, non-irritating ingredients.
If skin remains dry even after using toner and moisturizer, apply a hydrating and moisture-retentive face cream. Especially for dry skin types, a rich, highly moisturizing cream may be applied to the face—but avoid applying it too thickly.
Sun protection is essential after chemical exfoliation. UV radiation is strongest during summer months, and unprotected sun exposure can exacerbate post-acne hyperpigmentation. Immediately following a peel, it is advisable to avoid applying sunscreen directly; instead, use physical sun protection measures such as carrying an umbrella or wearing a wide-brimmed hat when outdoors. If sunscreen must be used, opt for a mineral (physical) formula to minimize potential skin irritation.
Importantly, chemical exfoliation should always begin at a low concentration and gradually increase only if tolerated. Overuse may compromise the skin barrier, triggering visible warning signs (e.g., redness, stinging, flaking). In such cases, reduce the concentration accordingly. If even the lowest concentration causes adverse reactions on the face, discontinue chemical exfoliation altogether.
