What is a potential risk of using an inappropriate chemical peel on sensitive skin?

Using an inappropriate chemical peel on sensitive skin can lead to hyperpigmentation. Sensitive skin typically has a thinner protective barrier and may react more adversely to strong or unsuitable chemical formulations. When the skin is over-exfoliated or injured due to harsh chemicals, it can trigger an inflammatory response. This inflammation can stimulate the production of melanin, leading to dark spots or discoloration that can appear on the skin. Essentially, the imbalance caused by an unsuitable peel heightens the risk of the skin darkening in certain areas, particularly in individuals with a predisposition to pigmentation issues.

On the other hand, excessive hydration, accelerated healing, and decreased oil production are less likely outcomes from using an inappropriate peel on sensitive skin. Sensitive skin is typically more prone to dehydration when subjected to aggressive treatments, and healing would not be accelerated but may actually be impeded due to inflammation and damage. Additionally, chemical peels generally do not lead to decreased oil production; rather, they often target the top layers of skin, leaving the underlying oil production mechanisms intact.
