What should you know about mild chemical burn?

Chemical peels and active products can disturb the outer skin barrier. Affected skin may feel hot, tight, tender or itchy and may look pink or red. Peeling can appear later as the barrier sheds damaged surface cells. The depth of injury is not always clear from appearance alone, especially on the face, around the eyes, or on darker skin where redness may be less obvious.

Stop the suspected product and remove contaminated clothing or jewellery. Rinse the skin with plenty of cool or lukewarm running water; do not scrub, neutralise the chemical, or apply another active product. Pat dry, use a plain fragrance-free moisturiser, and protect the area from sun and heat. Avoid picking flakes or blisters. Do not restart glycolic acid or another exfoliant until the skin is fully comfortable and a clinician has advised that it is suitable.

Get urgent medical help for eye exposure, severe pain, spreading swelling, large blisters, pale or blackened skin, breathing trouble, or a burn involving the mouth. Arrange prompt assessment if symptoms worsen, the area becomes increasingly warm or discharging, or healing is not progressing. A clinician can check depth and reduce the chance of lasting colour change or scarring.

Ask which ingredient may have caused the reaction, whether the barrier is intact, and when moisturiser, sunscreen, or prescription treatment can be restarted. Mention the product strength, contact time, body area, and any first aid already used.
