Chemical peels are categorized into three main types: superficial, medium, and deep. Superficial peels use mild acids (like alpha hydroxy acid) to gently exfoliate the outer layer of skin, suitable for improving skin texture and brightness. Medium peels penetrate deeper using trichloroacetic acid to target more pronounced skin issues like fine lines and moderate sun damage. Deep peels use stronger agents to treat more severe skin concerns and require longer recovery time. Your skincare professional can help determine which type is best for your specific skin needs.
