When you undergo a skin peel, the treated layers of skin gradually flake away and a fresh, new layer of skin is revealed. A reaction similar to sunburn occurs following the procedure. Peeling usually involves redness followed by scaling that ends within 3 to 7 days. Medium-depth and deep peeling may result in swelling and even blisters which, over a period of 7 to 14 days, may break, crust, turn brown, and then peel off. You will need to avoid direct sun and apply sun protection after a chemical peel because your new skin will be fragile. Skin heals more efficiently in a moist environment, so speak to your doctor about an effective moisturiser.
After a chemical peel, skin is temporarily more sensitive to the sun, so wear sunscreen every day (yes, even in the UK, and even when you are not sunbathing). Your sunscreen should read ‘broad-spectrum’ on the label, meaning that it protects against the sun’s UVA and UVB rays. Note also that your sunscreen should be at least SPF 30 and a ‘physical’ sunscreen (look for zinc oxide or titanium dioxide in the ingredients). Limit your time in the sun, especially midday between the hours of 10am and 2pm, and wear a wide-brimmed hat.
