hi, welcome to MuT !
here's a couple threads that might help you :
acne tips, talks and more
homemade skincare recipes and masks
a few tips i learned fighting acne :
*use gentle products, the harsh ones will strip all the sebum for your face, and induce a higher production of sebum to compensate
*keep your face and hands clean, as bacteria can cause acne
*wash your face every morning and night, but no more
*use a non comedogenic specific moisturizer
*wear sunscreen, the sun is a false friend
alas, the thing is, there is no real remedy. but if all the skincare products you have tried didn't have long term effects, i suggest you keep them for the moment and consult a doctor, see if a hormone imbalance is responsible.
