40% Salicylic Acid: Uses, Side Effects, and Drug Interactions

# 40% Salicylic Acid Overview Salicylic acid at 40% strength is a powerful skin treatment used mainly for removing warts, corns, and calluses from your feet and other parts of your body. It works by breaking down and softening the thick, dead skin that makes up these bumpy growths, allowing them to gradually peel away. This product is much stronger than over-the-counter wart removers you might find at a regular store, which is why it's often used by doctors and in professional settings. Because this product is so strong, you need to be careful when using it. Never use it on your face, genitals, or moles, and don't apply it to healthy skin around the area you're treating since it can cause irritation and burns. Always follow your doctor's instructions exactly and stop using it if your skin becomes too irritated or red. Keep this product completely away from children and pets, and wash your hands thoroughly after each use. If you have sensitive skin or diabetes, talk to your doctor before using this product since it may not be safe for you.
