I know this might seem like a personal and silly question, but it's a genuine one. I think everyone here knows there's a billion-dollar industry that scams people with products promising rejuvenation. The most well-known example is collagen consumption, which, as far as I know, doesn't actually make you "younger," because some articles I read had such poor sampling methodology that they were people with nutritional deficiencies, so it's obvious that any supplement would help... Anyway, is there really anything studied that's good for our skin and so on? I ask this because my aunts and cousins have already lost a lot of money because of it.

The issue of collagen supplementation is even more questionable when one considers that, regardless of dietary balance, there is no guarantee that ingested collagen will be directed specifically to the skin. It may be allocated to any other tissue or organ that requires collagen for structural maintenance. Unfortunately, surgical intervention remains the only definitive option, and given that many individuals consume nutrient-poor diets throughout their lives, there are few effective alternatives available.

Make up industry spends tons on this specific kind of research. You can be pretty sure that all legitimate creams and ointments have some kind of active ingredient that studies have shown to be "good" for your skin. It's not like there's some kind of one secret trick that everyone has failed to tell you, if there was you would find it in a Loreal cream for 200 dollaridoos a jar instantly. Mostly it just comes down to the same thing everything else comes down to that is good and balanced diet and healthy living habits, for skin specifically you should also throw in avoiding the sun.

Sunscreen isn't used for the heat.

>Regular sunscreen use retards skin aging in healthy, middle-aged men and women. No overall effect of β-carotene on skin aging was identified
this is just the first study that I found, but I've seen several showing regular sunscreen use is tightly correlated with a massive reduction in skin cancers, melanomas and overall skin aging
obviously this wont undo aging, but if you regularly use some form of radiation blocking on your skin while you are exposed to the suns radiation you will absolutely not age like someone who didn't

As you said, nothing in the world has anti-aging properties. Nothing.
But sunscreen helps you prevent premature aging, but how long it's beneficial without being exposed to solar radiation, I'm not sure.

Thank you, anon. But can continuous use really have a preventative effect? Would you recommend a type you've used before?
