At first they did not bother me because they weren't so prominent but they seem to be getting worse every day. They are thin lines that get deeper looking when I smile but don't spring back into place after smiling. I have used Differin on my face for the past 6 months to treat acne and I believe that the dryness made the lines worse. I also have Tazorac prescribed to me, I've heard this may be helpful in treating fine lines. Do you think this could work for me?
