What post-treatment instruction is most crucial after chemical peels?

After undergoing a chemical peel, it is critical for clients to always use sunscreen. This instruction is crucial because a chemical peel removes the outer layers of skin, making it more sensitive and vulnerable to environmental factors, particularly UV radiation from the sun. Without proper protection, clients risk hyperpigmentation, irritation, and prolonged healing time, as their newly exposed skin can easily burn and become damaged.

Using sunscreen helps to shield the delicate new skin from harmful rays, promotes proper healing, and reduces the chances of adverse reactions. For optimal results and skin health, the recommended broad-spectrum sunscreen should have a high SPF value and be used consistently after treatment, regardless of the weather conditions.

In contrast, while avoiding strenuous exercise may be advisable to prevent excessive sweating that could irritate the skin, it is not as critical as sun protection. Washing the face excessively can lead to further irritation, and applying heavy foundation can clog pores and impede the healing process, which does not align with the goals of a chemical peel. Thus, focusing on sunscreen use is the most essential post-treatment instruction in this context.
