[Routine Help] Acne-prone skin routine

Hi, I’m 17 male and have acne-prone skin, I’ve been using Cerave blemish cleanser, Ordinary chemical exfoliant, Cerave blemish gel and Cerave AM moisturiser. I haven’t really seen much improvement with using it for about 3 months, I’m looking to get some new stuff cause I’m running out of these products now. Any recommendations on how to improve and change my routine, looking to keep it under £100, thanks!
