Hello and welcome to healthcaremagic Acne and oily skin are interlinked. Acne, specially inflammatory acne are notorious for leaving behind post inflammatory hyperpigmentation. -I usually start my patients of inflammatory acne on topical benzoyl peroxide gel 2.5% for day time use. Erytop gel contains clindamycin phosphate 1% gel and can also be used similar to benzoyl peroxide gel. -At night I as my patients to apply a topical retinoid e.g either Adapalene OR Adapalene+clindamycin combination. Retinoids are good both for acne as well as post acne marks/hyperpigmentation OR alternatively once the acne is controlled, I start may patients on topical Azaleic acid gel twice daily, which works wonderfully well for 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. regards
