Hello and welcome to healthcaremagic
Acne is very common at your age. Treatment is guided by the severity of acne. It seems that you have inflammatory acne that are leaving behind post-inflammatory
hyperpigmentation.
-I usually start my patients of acne on topical
benzoyl peroxide gel 2.5% for day time use.
-At night I as my patients to apply a topical retinoid e.g either
Adapalene OR Adapalene+
clindamycin combination gel. Retinoids are good both for acne as well as post acne marks/hyperpigmentation
-I also decide to start my patients on
oral antibiotics if they have inflammatory acne.
Since acne is a recurrent condition and once your acne is brought under good control with oral and topical antiacne medicines, you should still continue to use a cream/gel e.g topical retinoid for maintenance of improvement. Topical retinoids are ideal for maintenance of improvement because they are comedolytic as well as antiinflammatory, thereby preventing the formation of new acne.
It is important to not to pick your acne, since it might leave behind scars/hyperpigmentation.
