[Acne] I am really tired of this, I really need help..

In the morning, I wash my face with Nitrogena cleansing (for oily skin and controlling spots) then tiny amount of 345 cream (dr althea) and then the sunscreen. Before sleep I wash my face again witg the cleanser, put a little bit of 345 cream and then isoromyderm on the spots. I have just finish a 10- day course of doxycycline, and as you see still there.. I am really tired of this skin sometimes it becomes much worse, I am already 20 Y.O and trying to care about my sking from 5 years ago, however, nothing work to stop these 🥲 I really care about my food and try to eat healthily all the time…
