You have to be very careful due to the location of your abrasion. I luckily have only had one tretinoin burn. It was on my hairline. What cured mine: A dab of Desitin (diaper rash cream). I like Desitin because besides Zinc it has other healing ingredients. Great for diaper rash! Over this I applied Aquaphor. You can take a q-tip and dab some zinc based cream on it. Then, dab on top some Aquaphor. It will heal.
