Pushing 50, wear sunscreen every day and moistorizer every night, on the brink of menopause. Used get botox and filler before my immune system destroyed entire thyroid and attacked my autonomic nerves to the point that I barely have a swallow reflex. I'm wondering if a thread lift for sagging jowls and crows feet is safe for someone with autoimmune problems? Is it also a safe "dress rehearsal" to see how much skin I want to pull back before I get a permanent face lift.
