has anyone found a miracle 'cure' for sagging skin?

i searched this sub and there seems to be a lot of suggestions to do longer fasts (>24h). my concern is that i will lose even more weight as a result. i'm already in a good place as far as my body is concerned. and frankly my friends seem concerned...one that i hadn't seen in years straight up said 'i liked your face more when it was fuller'. i don't know how i can gain weight only in my face, so i am wondering if i can do something to look less older and sadder...i'm a 50 y.o. man and went from around 200 lbs to under 170 now (i never weigh myself). thank you! via /r/intermittentfasting https://ift.tt/JBK5mZn https://ift.tt/89Ilben
