Pigmentation can be due to many causes, such as post-inflammatory pigmentation after a rash or allergy flare-up, certain oral medications, and excessive sun exposure over the years leading to sun-damaged skin.

​

A variety of pigmented lesions can develop on sun-damaged skin (e.g. freckles, solar lentigenes, melasma, Hori’s nevus). These vary in their depth, behaviour and response to treatment.

​

Treating pigmentation requires careful personalization.
