Hello Christine
Thank you for your question. In addition to what Dr Shane has mentioned, chemical peel can be used to treat pigmentations such as freckles and sun damaged skin.
The peel will help to remove the top layers of the pigmented/ sun damaged skin and stimulate collagen production.
Chemical peel can be done in combination with laser therapy to give you the best result. Speak to a doctor to find out more.
Regards,
Dr Jiwei Wu
