Hello, my name is Ricky I am 16 years old and have been having acne probably since I was 12 and I have never had cystic or super severe acne just mild acne maximum 15 lesions at a time and these just leave red marks. Now that is have been on differin, clyndamycin, doxycycline and tetrinion for the red marks my acne is under control maybe 7 pimples max but they still leave red marks and my face is covered in them. What should I do? Also acne always comes back in the same spots mostly cheecks. Thanks!
