If you have a history of abnormal pigmentation, skin scarring,
Afro-Caribbean or Asian skin, or freckles and red hair, skin peels are
not recommended.
Hyper-pigmentation can occur which is when new skin has too much
pigment and will turn to brown blotches in the sunlight. You should use a
high-factor sun-cream to prevent this.
Permanent scarring is a very rare risk.
