Hi I would advise you to first consider using creams and change your diet and include plenty of fruits and vegetables. change your life style and exercise regularly. If you still have acne then consider oral tablets and at the last take the peels. peels are generally safe and give good results for acne or dark skin but if your acne recurr after  finishing the peels you are back to having the ssme problem. so I would advise you to treat acne well before trying skin lightening treatment
