I have less experience with Derma Rolling as I do with TCA peels for treating fine lines and wrinklking. I can only say, TCA (depending on the strength of TCA, lenth and pressure of application) can dramatically improve wrinkling and sun damage. If you are willing to have the downtime that comes with a more aggressive TCA peel, you will have excellent results. There may be some benefit to following up a peel with derma rolling, but I would to a TCA peel first. Click on the link below for before and after photos of a TCA 35% peel with a heavy frost.
