Smoking cigarettes also seriously ages a face, and fewer women smoke these days.
I think it’s a combination of pressure to look younger, permission to look and act younger (that is, people no longer listening to the message that it’s time to climb into the rocking chair and die when they hit 60), and better products, Botox and fillers.
There is an upper limit to nutritional glycine (and collagen) as it is an oxidisable amino acid that in some people can cause inflammation if used in excessive amounts. The metabolic break down products of oxidised glycine are the inflammatory component.
As a side-note I take 500mg Vitamin B3 (niacinamide or nicotinamide*) twice daily because I am Australian. Too much life-long sunshine and UV damage. Vitamin B3 has its effects at the mitochondrial level in cells and cellular mitochondrial efficient energy production. Dermatologists have started to recommend topical skin-absorbent gels for Vitamin B3 dosage. People claim they look younger with the resultant effects of the Vit B3. It could be an adjunct therapy for those seeking youthful looks.
Niacinamide and nicotinamide both represent the same chemical compound, which is the amide form of vitamin B3. They are interchangeable names for the molecule that plays a critical role in cellular energy production in the body. Both terms describe a compound that is vital for numerous biological processes, including the conversion of food into energy.
I agree with you. I think people today look much younger than their years, unlike in the past. I’ve seen pictures of my parents in their 40s/50s/60s, and they looked “old.”
You have now touched on one of the great controversies in the anti aging world. About 5 years ago Dr. David Sinclair wrote a book which basically touches on NAD and its precursors, including NMN and NR as reving up your mitocondria. Other people have gotten into this discussion as well. There are some claims about NMN and helping with skin cancer. NAD is connected to Niacin B3
Note this is quite controversial, some were concerned about NMN/NAD supplementation in cancer. This studies shows a good result but some are concerned about risk

I have a couple of dark spots that started 15 years ago. I had them frozen once but they came back. I have been using a commercial niacimide elixir on them for a couple of years and they have definitely faded from what they used to be. Could be other things in it but I really use very few lotions
I took NMN orally for about a year and noticed no effect at all on my energy or the condition of my skin or anything else. Non-slow-release niacin causes my head to burst into flames, so I know that does something, but whether it’s effective or has any long lasting effect on my skin is another question entirely.
I hate to think I’m being led down the same sort of snake oil path as Big Med, just without any oversight so I can’t even be sure I’m taking what I think I’m taking. On the other hand, I hate to think I’m missing out on something that might be the hack of the century! 
So true. Early 1960s - visiting distant cousins in eastern Kentucky, U.S., rather a ‘land that time forgot,’ even then (just as the country as a whole approached a period of rapid change). Very friendly, welcoming people, but ‘hard’ - hard lives, hard existences, a dirt floor in part of the house. They took little for granted, and they all smoked.
Absolutely! Attitude and knowledge of what is possible changes everything. My grandfather and grandmother on my dad’s side, born 1903 and 1911. They were thus in their 60s and 50s as those same 1960s progressed. ‘Old’ - they had grandchildren, after all. They were settled, and somewhat in stasis. Nothing wrong with that, per se (if one is happy), I feel, but to live that way now, personally, no… There are always new things.
They didn’t die early; he lived to 97, she to over 100. So, for 40 or 50 years they were ‘old.’
I live very near a converted rail road line that’s now for walking, running, cycling, dogs, etc. Many people in their 50s, 60s, 70s, or even older, and they move and look good. Didn’t see nearly as much of that 60 years ago.
That is so interesting. I have wanted to try it but the potential side effects being unknown scare me it sounds like the science it very unsettled. I took NAD for about a month and found I was more tired but that could have been my own nonsense. Other than the serum and whatever else is in the various lotions I buy and then barely use, I also take Niacin whenever I remember. You are supposed to take it in the morning but I always forget. It seems to have no effect on me. Meanwhile this guy talks all about the benefits he has gotten
