From past 2-3 years, i am experiencing a change in my face prominently like losing elasticity,fine lines and blemishes. I tried products available in the market like .2% retinol, vit c and peptides.. but not helping much. How can I slow my aging process. I prefer eating home cooked food and all the veggies. I have oily skin so can't apply too many creams/gels. Do I need to visit a doc to get the right teatment?
