I accidentally got some of my tretinoin cream (0.025%) on my eyelids and now they are burning/peeling. How can I get relief?

The eyelid skin is very thin and easy to get irritated with retinoids.If retin-A is too strong or irritating, consider using a mild retinoid cream may be best. 
Read about Retinoids on Retinoids 101 (see link below)
As well, use wide spectrum UV protection with SPF like Spectrase.

Thanks for your question.  If you don't use any more retin-a on the upper eyelids, the burning will eventually stop and things will be fine.  The upper eyelid skin is far to delicate to tolerate most retinoids.  We do recommend using it two to three times per week on the rest of the face, and may increase the frequency of use if you are not too dry or peeling, or live in a more humid environment.  You might put some gentle, unscented cream moisturizer on the eyelids, or even plain Vaseline for a day to two to help them heal.
Best of luck!
