Hello. Thank you for writing to us at healthcaremagic Oily skin is prone to get acne. Acne in oily skin can last for months and even years. The topical gel that you have been using contains clindamycin 1% gel which is an antiacne antibacterial for inflammatory acne. However, in acne and oily skin conditions, it is also desirable to use a topical preparation that would not only prevent new acne formation as well as treat existing ones. Topical retinoids e.g topical adapalene is one such product. Adapalene gel is anti-inflammatory as well as comedolytic. On account of its comedolytic action it would prevent initiation of new acne while treating existing ones. Topical adapalene is therefore ideal for maintenance as well. Retinoids also help lighten the spots/ marks left over by previous acne. I suggest that you visit a dermatologist in your region. Your dermatologist will assess the exact skin condition and advice accordingly. Regards
