Sensitive skin types may receive chemical peel treatments safely. However, it is important to choose a peel that is appropriate for each individual’s skin type. Performing a more aggressive peel on a sensitive skin patient could be disastrous, especially if the patient has not built up a tolerance for chemical exfoliation. For a patient who has very sensitive skin, I would suggest to start with a very light peel with acids that have larger molecules and are known to be less irritating. Mandelic and lactic acids are a few examples of such acids. Furthermore, for a patient who tends to be reactive to skin care products and has a history of allergic reactions, I would highly suggest or require a patch test 24 hours prior to the actual procedure. If there was no abnormal reaction, it would at least be known that there is no allergy present that could cause adverse effects.
