The amount of chemical peel treatments you will require depends on your specific skin care goals. For instance, if you are treating acne scars with a medium chemical peel, your doctor will likely recommend multiple treatments to achieve the best results. Alternatively, deep chemical peels may help you reach your skin goals with just one session, though this type of chemical peel requires significant downtime and recovery period. Ultimately, your doctor will recommend a certain amount of chemical peel sessions in your treatment plan to help you achieve optimal results.
