Heyy
I am 19 now, I have has this constant red blemishes/acne on my cheeks mostly since puberty. I have had different routines products. For few months I was using all ordinary products (the exofliator, cleanser, hyaluronic acid, ninacimide acid and moisturiser) which made my skin worse and caused my skin to have large red pimples that would hurt. I stopped that 3 years ago and minimised my routine to Cerave SA cleanser, moisturiser and sunscreen + using ordinary exfoliator once every two weeks. This has helped a little but still no major difference. Recently about a month, I have included the Cosrx advanced snail dual essence and all in one cream to my routine which has helped a lot with my skin texture, brighting and giving my face the glow. I’m still looking for something to clear my skin 😩 Please tell me where I am doing wrong or how to improve my skin. I also have large pores and blackheads around my nose. 
Thanks in advance ❤️
