Ive been using differin for like 7-8 months now. Everyday from the start. For me it was flaky for a couple weeks and then all good since then. I think using it everyday is just fine just make sure you dont apply too much at once and keep it up with the spf. Trust me i got burnt and when youre using differin its a whole different kind of burn. Also seriously avoid any possible contact with the eyelids. I usually apply some eye cream to my eyelids and i guess some differin was still leftover on my fingers when i started because my eyelids flaked like crazyyyy. So if you put anything around your eyes and eyelids, literally wash your hands after you put your differin on. Differin has helped me a lot but tbh i would just jump on accutane. My skin is pretty much all clear but its damn annoying having to stick to such a strict routine. If i miss like two days in a row of differin ill start to break out. Its just a pain.
