Suggest Medication To Improve My Complexion

Hello doc. I'm 25yrs old married women and have a combination skin type. My skin looks dull and uneven. I had been to dermatologist in bangalore. She gave me AHA glow face wash and asked me to apply Strea C and Strea A on face.Since those were very costly, I just bought strea A for RS.1200. I use AHA glow face wash but it does not make look radiant.When I use this face wash I look darker than my original color.Please suggest me a good brand cream and a face wash which can improve my ccomplexion and give me more radiant and glowing skin. Right now I am using garnier fairness face wash and clean and clear moisturiser.
