hi..thanks for the query.
I understand your concern, but this is nothing you should be very worried about.
You should start a skin care
regimen that will improve your skin and take care of the acne eruptions on a daily basis. You can start using a broad spectrum gel based sun screen 20 mins before going out and repeat it 4-5 hourly.Use non comedogenic creams as moisturizers like Cetaphil moisturizer and Cetaphil cleanser for sensitive skin.These will avoid further darkening of the skin and the post chicken pox/post acne marks.Avoid fairness creams and any OTC lightening agent application on full face.
gel on the pimple twice daily.You may also use Adapalene
gel at night ,starting with alternate night application and making it daily as your skin gradually tolerates it.
and Comedone extractions may be required intermittently and can be advised by your dermatologist
.If you follow a good skin care regimen daily, it will make your skin healthy and clear soon.
Hope this helps..take care!
