How to Repair the Skin After Chemical Exfoliation

In recent years, “acid peeling” (chemical exfoliation) has grown increasingly popular. Many women believe it helps reduce acne and blackheads and improves overall skin appearance—yet they often overlook the critical step of post-peel skin repair. Details are outlined below:

After acid peeling, the stratum corneum becomes thinner. Therefore, high-performance skincare products—such as 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 hydrating, soothing toners and lotions, along with gentle, minimally formulated masks.

If your skin remains dry even after using toner and lotion, apply a hydrating, moisturizing cream. Especially for dry skin types, a rich, emollient moisturizer may be applied to the face—but avoid applying it too thickly.

Sun protection is essential after acid peeling. UV radiation is strongest during summer months, and excessive sun exposure can worsen post-acne hyperpigmentation. Immediately following an acid 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. Even if you do use sunscreen, combining it with physical sun protection methods is recommended to minimize skin irritation.

Importantly, acid peeling should always begin at a low concentration and gradually increase only as tolerated. Overuse may compromise the skin barrier, triggering visible warning signs (e.g., redness, stinging, flaking). In such cases, revert to a lower concentration. If even the lowest concentration causes adverse reactions on the face, discontinue acid peeling immediately and consult a dermatologist.
