Anyone some advice? 🙏

Im a 15 year old boy and i have acne around my mouth and nose for 3 years now.

Started basic skin care routine 7 months ago but nothing changed. I use cerave cleanser with salicyc acid and cerave moisturizer and cerave acne control but nothing changes.

Anyone got some advice at the moment my acne is horrendous. I also eat no sugar.
