Hi Paras..Thanks for your query.
For acne control , you can use Clindamycin
gel twice daily on face.Certain cases require Oral antibiotics
, but that can only be advised on inspecting the actual nature and extent of acne you have.Avoid retinoids as your skin is dry .You may later add them after using proper oil free moisturizers.
The treatment for the post acne scars depend on the nature and extent of the acne which caused it.
For hyperpigmented scars , the treatment options include:
1)Topical depigmenting creams: creams containing Hydroquinone
, Kojic acid, arbutin etc.
2) Chemical peels
: Glycolic peels for a few sessions from an experienced dermatologist
every 2-3 weeks.
Sunscreens should be applied on the face always to prevent these scars from getting darker. You should choose broad spectrum oil free sunblock and apply 20 mins before leaving your house and reapply every 4-5 hourly.
Hope this helps.Take care!
