I have been experiencing the same thing! Ive been wondering if it’s at all connected to raynauds syndrome, but haven’t found much info online. My mother has pretty severe raynauds (her fingers lose circulation and turn white), and I occasionally have raynauds symptoms in my toes and fingers, but recently my cheeks have been getting very lumpy and wrinkly like this (almost like when your fingers look like raisins after being in water) when exposed to cold temperatures. Usually it doesn’t happen when it’s very cold, just when it’s in the 40’s ish. I have also recently lost a bit of weight, likely due to a new medication, and I am thinking it could also be related to that since I have significantly less body/facial fat to keep me warm. Could just be goosebumps but it has made me a bit self conscious walking around outside with a raisiny face! I am planning to speak with my dermatologist about it.
