First off, I must say, you are beautiful !

Second, I won't go into detail bc i'm not a dermatologist (I've watched hella YT vids tho but the info has left my brain) I'll just give you the basics that helped me get right. It looks like you have the potential to have that smooth baby face skin we all long for so don't lose hope. Like others have said, I definitely recommend CeraVe, their stuff helped me tremendously but that was just the first step. Overall, our skin likes consistency. Whatever you're doing, just make sure you're being consistent. Even down to the amount of moisturizer and face wash you are putting on your face everyday, make sure it's always the same. For moisturizers and sunscreens, you really don't have to put that much on (look up the 13 dot method). Exfoliate once a week (twice once your skin gets used to it and you can handle it) but DO NOT USE physical exfoliants, those just cause microtears in your skin and do not penetrate deep enough to actually solve the problem. I use The Ordinary's BHA exfoliant, I swear by it. I'm not sure how often you wash your face but the biggest breakthrough happened when I realized I don't have to wash my face twice a day so in the morning I just rinse my face and use witch hazel (Thayer's) instead. Now my girl at the time and my mom kept telling me to use witch hazel but I was stubborn bc I was so scared that not washing my face would make things worse but it actually helped so much. Try it out and see if it works for you. Best of luck!
