Notes for this study:
Application of a nightly cream containing 0.05% retinoic acid, but not 0.01%, was able to significantly improve signs of photoaging relative to control in regards to smoothness, small wrinkles, tightness (reduction in elasticity), miscoloration, and overall ratings.

Side-effects were all mild in severity but included dryness, reddening, and a burning sensation.
