1012 Whereas, photo-aging (exposure to ultra-violet light) and chronologically aged skin are involved in a cascade of cellular and molecular signaling mechanisms (mainly due to oxidative stress)
The mechanism is only partially understood but involves reduction of gene and protein expressions of fibrotic and inflammatory markers such as TGF-, TNF-, IL-2, MMP-9, vimentin and enhancement of antioxidant ability by increment of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and by preservation of mitochondrial function [215]
[1] [26] This reduces the risk of hypoglycaemia, though this risk increases significantly when used in combination with insulin or sulfonylureas, which may require dose reduction of these medications
Using semaglutide as an example, standard dosing starts at 0.25 mg per week and increases every four weeks
