Hello, Thank you for posting on HCM. Swimming in chlorinated water can easily lead to tanning. Always use good quality water-proof sunscreen like Ansolar sunscreen cream (GSK)/Cetaphil UVA/UVB defence (Galderma) before going for swimming. Acne, as you must be aware is pretty common condition caused chiefly due to hormonal influence and clogging of pores and followed by infection and inflammation. Treatment usually depends on severity of of acne. Usually I advise oral antibiotics with or without oral isotretinoin. Apply cream containing nadifloxacin twice day and gel containing benzoyl peroxide and adapalene at bedtime for 1 hour followed by face wash. Use good quality face wash like Fash foaming facewash and a moisturizer like Cetaphil DAM on regular basis. Avoid junk food as far as possible and include plenty of fresh fruits and vegetables in your diet. Hope this will take care of your condition. Thank you Dr Hardik Pitroda
