Facial Exercise to Reduce Sagging - Studies?
I'm confused. Many people swear that facial exercises have made a difference for them & I would think that resistence training would tighten the facial muscles & therefore reduce some sagging, even if it doesn't tighten the skin itself or replace fat. Most dermatologists etc claim that such exercises are useless, as no studies have proven their validity. But I haven't been able to find any articles in dermatological/cosmetic science journals reporting on it at all. Does anyone know any sources?
