I never suffered from acne as a child...and then hit my late twenties and my beautiful skin just I dunno.....
They way I treat myself is this, I obviously ensure my skin is kept clean, especially after I've been out I wash it with a mild face wash, but I also take high strength vitamin C, and Star flower oil, the Starflower oil I take for other reasons but one of its unexpected side effects is the most gorgeous glowing skin ever, and shiny hair and strong nails....of course then I read that article about women in their 30's being at their aesthetic peak, so it could just be that it's all going to go down hill from here for me!!!
Try not to stress, eat well, drink lots of water, do not use harsh treatments for your face it makes the problem worse. Inshallah it will clear up.
