hi..thanks for the query
Try using cosmetic formulation and make ups as minimal as possible.Use hyo-allergenic brands with minimal perfuming and coloring matter.Every time u use a make -up, remove as early as possible using a soap free cleanser.The above steps take care of a sensitive skin.
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 .These will avoid further darkening of the skin.
gel on the pimple as required.
Hope this helps..take care!
