Can Retinol affect my sleep?

Yes! I've had the hardest time finding evidence of this issue, but tretinoin cream absolutely interferes with my sleep. It took me years to figure out the cause of my sleep troubles, but once I eliminated this cream I slept better. After talking to my derm she suggested I try the cream in the morning (using caution with sunscreen of course) but a few weeks in the sleep troubles returned. I have no doubt this disrupts my sleep.

Hi, i agree with Suzanne. Check out the link she provided. Insomnia is listed as a serious side effect. Just wanted to back up her answer, please contact your doctor asap & i'm sure he/she will come up with something to help you out.

Is the Retinol a topical or an oral product?
If the Retinol is taken orally (by mouth) then sleep problems could be a sign of a serious side effect. You should see your doctor.
