Name a common contraindication for receiving a chemical peel.

Active acne or dermatitis represents a significant contraindication for receiving a chemical peel due to the sensitivity and inflammation inherent in these conditions. Chemical peels work by exfoliating the top layers of skin, which can exacerbate irritation and inflammation in already compromised skin. Not only might this lead to further skin issues, like increased redness or potential scarring, but it can also hinder the healing process.

On the other hand, while sunburn is also a contraindication, it is more about the skin's current condition rather than an active skin issue like acne or dermatitis, which are ongoing inflammations that could worsen with the application of chemicals. Dry skin, while a concern, does not preclude the use of chemical peels as they can sometimes even be beneficial for hydration and regeneration. Fine lines are not generally seen as a contraindication because peels can be particularly effective for treating signs of aging, including the appearance of fine lines.
