What Are Some Effective Treatments To Permanently Clear Painful Blind Pimples After Using Deriva Me And Benzoyl Peroxide For Two Years?

I have been using deriva me and benzoyl peroxide for a long time(2 years) for my acne. Though my oinples had reduced alot like 70% , they are not going away permanently, I am mostly facing blind pimples which are painful. Can you please suggest what can be done next to clear out my skin completely? P.S.- I have pinples for 5 years and started medications two years back. I am 25 years old.
