As
Asian people age, their skin often becomes irregularly pigmented.
This shows up as dark patches on the skin. Irregular pigmentation
and hyper-pigmentation can also be caused by inflammation.
If an area of the skin becomes inflamed from an insect bite,
trauma or from pimples, a darkened area can be left behind
as the inflammation subsides.
Causes
of Irregular Pigmentation:
- Excessive
sun exposure
-
Pregnancy
-
Birth control pills and hormone treatment with estrogen
- Inflammation
from insect bites, acne, trauma, or other causes
Treatment
of Irregular Pigmentation:

steroids. These can cause permanent skin damage including

- Tretinoin
applied daily for many months will treat irregular pigmentation.
- Daily
use of sunscreen will help prevent irregular pigmentation
