Welcome to health care magic.
1. Pigmentation around the mouth could be due to conditions like seborrhoeic melanosis
( darkening due to oily skin), familial, vitamin B 12 deficiency, thyroid abnormalities . Kojivit is a good lightening cream which could help you to lighten the pigmentation after ruling out underlying problems.
Few sessions of chemical peels
by a cosmetologist will also help.
2.for your recent chicken pox
scars, kojiviit can be applied on the dark scars. However, if they are depressed scars, you may need dermaosurgicsl procedures like subcision. This can be done after the scars are mature , ie,after 3 months. You should also use a good sunscreen.
- you can make a facepack of ground almonds and lemon which act as a mild chemical peel.
Tomato and cucumber act as good astringents.
Have a good diet with lots of coloured fruits and vegetables rich in beta carotene
, vitamin c like tomatoes, capsicum, carrots, pumpkin and broccoli.
Hope this helps.
