Can Adapalene gel be used to reduce inflamed papules?

Hello doctor,

I am a 22-year-old female. Two years ago, I started developing mild to moderate acne. My dermatologist suggested I use tablet Doxycycline, Adapalene gel 0.1 %, and Clindamycin Phosphate solution for one month. After the second month, I started developing new inflamed papules. So, my doctor prescribed the tablet Doxycycline again with a dosage of 200 mg daily for the first two months and 100 mg for the next two weeks. I have also used capsule Isotretinoin and tablet Gentamicin in the past. Unfortunately, there is minimal improvement by the end of three months, and I am still developing new inflamed papules. Should I use a higher concentration of Adapalene gel? Kindly advise.
