Is waiting really the key factor here? In my experience, burns often come from applying too much product at once, not just from short wait times. I'd focus on thinner layers instead of longer breaks.
Tried the video trick and it actually works. I set a timer for 5 minutes between coats, which feels like forever, but my skin doesn't get red anymore. Thinner layers help too, but the waiting part was the game changer for me.
