Acne treatments can be both harmful and beneficial for the skin, depending on the type of treatment and how it is used. Some treatments, such as harsh chemicals or abrasive scrubs, can damage the skin and cause irritation. On the other hand, certain acne treatments, like topical retinoids or salicylic acid, can be beneficial in effectively treating acne and improving skin health when used as directed by a dermatologist. It's important to consult with a healthcare professional to determine the most suitable and safe acne treatment for your specific skin concerns.
