Some heavy lifting for the claim that skin impacts health comes from this: > it's thought that intrinsic factors are responsible for the tiniest fraction of the classic "aged" look, while UV light is responsible for over 80% of visible skin changes. Here's the result from the study this links to: "By calculating statistical correlations between the four clinical clusters (wrinkles/texture, ptosis, vascular disorders,…

Smooth, soft and clear skin is definitely correlated with youth. It conjures the image of babies in most people's minds. Deviations from that indicate a degree of aging depending on the type and extent.

That doesn't contradict what I said.

I like to try and guess people's ages. In real life, or on video, where their personalities influence my guess, I'm much worse than when looking at a still image. With a still image often the quality of a person's skin is the only giveaway, and when that is the case I'm remarkably accurate most of the time. So I'm skeptical there's much one can do, and people's skin seems to age at roughly the same rate.

Easiest way to guess a person's age is by the relative size of the ears, that never stop growing.

Tiny ears - teenager. Huge ears - senior.

I was agreeing with you. Upvoted your comment too.

There's questionable reporting in some parts of the article which makes me doubt how seriously I should take the rest of it. Case in point with the concept of moisturizer adding moisture. While the name implies that that's what it does, it actually prevents moisture your body provides from escaping, it doesn't add any moisture that isn't already there. While the end result may seem similar, it isn't, for example you…

Not true. There are different classes of moisturizers, some are water based and do actually add moisture. Then there are oilier ones that only keep moisture in. I knkw this, because my skin is so dry and missing any protective layer that I have to apply both in sequence.

Yep, humectants vs occlusives!

This is why, for example, you should never apply pure hyaluronic acid on dry skin/hair: it's a humectant, which means it works by sealing in existing moisture. You have to apply it to damp skin/hair to get the intended benefit.

In late 2020 I committed to only taking cold showers. I note several upsides after nearly three years of this: - easier to forego caffeine, as cold water in the morning leaves me wide awake - easier to use less water, in part because it's so easy to get out of the shower into a warmer environment - mental health benefits, including increased confidence dealing with things I don't want to do but which are my adult dut…

In the peak of summer temperatures (especially this year), this is not exactly true.

I assume the vast majority of HN readers live in climate controlled residences where the temperature inside the residence and bathroom is more than the temperature of cold water, even in peak summer.

I wonder how much of the value of moisturizing is from massaging the tissue and working waste into the lymphatic or circulatory systems for disposal.

I've been wondering this, too, and remembering back to childhood when my mom advised always moving from extremities inward towards the heart (sunscreen, toweling off, etc).

Isn't that because moving away from the heart would force blood back against venous valves, possibly doing damage to them?
