Hello doctor, I am 32 years and I am concerned with the my dull skin.. lately I started noticing uneven texture with minute bumbs along with fine line. I have dry skin and some what acne prone. I heard that retinol helps in getting rid of fine lines. I also have dark circles. I used retinol serum of 0.3 percent concentration of local brand but it dint seem to work much..please suggest me some retinol serum and a good under eye serum or gel.. Thankyou
