and yea, vasoconstriction is vasoconstriction and we know nicotine (among other stimulants) causes it, and therefore, it's going to reduce blood flow to the skin. reduced blood flow = less oxygen/nutrients. over time, this can slow down the healing/regeneration process of the skin, which would lead to a more aged appearance. this also effects hair follicles.
there's not much else to prove here; it's cause and effect.
nicotine patches and gum have been around for quite awhile, and the blood vessel constriction is a fact, and therefore, it will affect skin/hair health.
it's just to what degree. clearly, it's more with analog cigarettes where you're sucking on literal smoke.
personally think it's less a problem with age. age limits are arbitrary and likely have no basis in science (within reason). however i do think it could be advantageous to require a variety of ages of people, and somehow weight their input, but that process may destroy the inherent value of a representative democracy; if we let everyone speak nothing will get done.
personally i think hard term limits and ranked choice voting would fix the majority of issues caused by generational gaps.
the issue is not with individual doctors or nurses.
the issue lies with for profit healthcare providers being slaves to the insurers. i work with providers daily; they are overworked and often are not able to provide the best care possible because the system sees people as a collection of data/telemetry to optimize.
it's disgusting, shameful, and damn near barbaric. not if you have a lot of money though.
inhaling carcinogenic smoke to get nicotine would age you more, but nicotine itself also has adverse effects by constricting blood vessels, which would affect how much oxygen and nutrients are able to reach the dermal layer. this would also affect hair follicles.
yeah i'm in my 30s and i get routinely carded at events and people place me in my late 20s still.
a lot of it is genes, but i also: have a good skin care routine, use sunscreen every day, rarely drink alcohol, and use nicotine rarely. those are big factors that shouldn't be discounted.
i hate microtransactions, but as they go, this implementation is fairly benign.
