What are the negative consequences of chemical peels?

Peel consequences: Darker skinned patients are at higher risk for pih(post inflammatory hyperpigmentation) after chemical peels.

Peel complications: Potential complications include hyperpigmentation, hypopigmentation, scarring, infection, cold sores, uneven color or unattractive appearance to skin, need for repeated treatments, sun sensitivity (and increased need for sunblock), swelling and displeasure with result. Hyperpigmentation or dark spots are the most common. Cold sores can be prevented usually with medication. Most of these are rare.
