hi..thanks for the query.
You should start a skin care
regimen that will improve your sensitive skin and take care of the acne eruptions on a daily basis.
You should 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 skins well as dryness and itching of the skin.
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. I would advise you to start the Adapalene application after adequately using the moisturizer for sometime and only when itching /dryness has completely stopped.
and Comedone extractions may be required intermittently and can be advised by your dermatologist
Hope this helps..take care!
