Acne Issues

Patient: I am Natasha. I have been suffering from acne for quiet some time since the past 1 yr. I started the use of adapalene gel followed by clindamycin at night. The problem with the acne on my face was that my skin shade had grown atleast 3-4 shades darker. With the use of the above treatment though the acne has reduced, yet the darkness of my skin continues and i feel a bit of burning sensation when i go out in the sun.Please suggest
