"I'd love some support from other Differin users [..]
I'm not exactly on Differin, I'm on Epiduo. But it does contain Adapalen (and BP), so I can understand you.
Personnally, it has been a week. My skin is dry and red, and it cannot support more than an application every two days, or it's like a huge sunburnt haha.
And you, how are you, guys?
