Hi doctor, I am 26 year female with very oily skin n pores on my cheeks. I regularly use sunscreen Photostable which makes my skin look more oily and look dull. My skin is light brown and dull. I want to lightening my skin at least 2 shades. I am getting engaged in 2 months. I don't want to use any based steroid creams and no chemical peel. History- 2 years back I had used cligel and tretinoin cream for acne which gave me flawless skin with no acne anymore and glowing skin but now I am using again trying those creams but I dnt see any difference in my skin. Can you please suggest me good skin lightening cream without any side effects for long use. I value your advice. Thank you.
