Step-by-step explanation:
The frequency of re-doing a service when using a chemical peel can vary based on several factors, including the type of peel, the concentration of the chemicals used, the individual's skin type, and the desired outcome. Chemical peels reduce microbial load on skin by utilizing mild chemicals to remove dead skin cells, promote cell turnover, and cleanse the tissue through either gentle or firm scrubbing. Generally, lighter peels may be repeated every four to six weeks, while medium to deep peels may require several months to a year between treatments to ensure proper healing and reduce the risk of complications.
