Please correct me if I'm wrong here, but Retin-A and it's sisters, Taz and Differin, remodel the skin at the level where the wrinkles live, so as long as it is used, it improves the overall condition
of the skin, not just the targeted
areas that Botox and fillers do, is this right? And for a fraction of the cost. They actually stimulate the production of collagen and elastin, I believe.
(Quote from Smartskincare.com
"Reducing skin wrinkles with tretinoin (Retin A, Renova)
Retin A and Renova are the best-known brands of tretinoin (a short for trans-retinoic acid), an active metabolite of substance related to but distinct from vitamin A. To be precise, tretinoin is a biologically active metabolite of vitamin A. Tretinoin produces multiple effects in the skin. It works by triggering molecular switches in skin cells called retinoid receptors. These switches affect many intracellular processes including cell growth and differentiation, synthesis of proteins (including collagen and elastin), sebum production, and possibly even the cell's lifespan clock (telomeres). Furthermore, tretinoin indirectly inhibits matrix metalloproteinases (MMP), the enzymes that break down collagen and elastin, the skin's key structural proteins. MMP become overactive as we age and contribute to wrinkles and sagging skin. Overall, the biochemical effects of tretinoin are numerous and only some are well researched."
Even if we had surgery to "remove" the wrinkles, it wouldn't stop the ageing process! But regular use of sunscreen with a high SPF/PPD is very important in slowing it down. Don't you agree?
