I Work in Full Sun All Day Twice a Week. Can I Use Retin A at Bedtime?

Please help me in making the right decision. should I start retin A at bedtime. I work in full sun twice a week all day long in texas. Does the benefits of putting retinA A on my face outweigh the risks? I used it before few months ago before I took the outdoor job and I had tons of wrinkles appear under my eyes after one week of usage so I stopped. Most of those wrinkles are gone which appeared over a week span of time. I want to start again only if it will prevent more wrinkles. missy
