Note: you do need to wait a few months for the fatty acid composition of your skin to turn over.
Neat. Curious how to interpret this when you are tanned some. My understanding is that doesn't change your skin type, but you do build some resistance. That not the case?
You have a base level of resistance determined by your genes. When you get burned you tan and that burn is a function of time spent out in sun multipliednby that base protection. Tanning is our bodies response to the damage done by this as a form of preventing more damage. The damage however is accumulative.
Fast forward a few years and I'm back to where the first few days mowing the yard will see me get burned. Give it a few weeks and I can go longer without a hat.

My ultimate dream is a pair of magical glasses with a small knob on it, which when turned adjusts the wavelength you can see from deep radio all the way to high energy gamma. Just imagine seeing the entire spectrum.
You want Geordi's VISOR from Star Trek.
There's a video which shows how you look like to a UV camera when you put sunscreen on. Also glasses with UV filters: https://www.youtube.com/watch?v=o9BqrSAHbTc
The video was cool but I'd also be skeptical of how they imply that freckles (including UV spectrum freckles) are "damage" to the skin or undesirable. It's neat that people look different under UV, and it's a cool adaptation that our skin pigments seem to target UV differently that visible spectrum... that's all I would confidently take away from the video
Sure, they are an adaptation. One that's best avoided _while you can_
Every time you get a "sunburn" and your skin turns red? That's DNA damage. The body is good at repairing that, but not perfect. Best not to take damage in the first place. And if you do, to at least reduce the total radiation amount.
We shouldn't be singling out people based on their appearance of course. But there should be more awareness that skin damage is cumulative, and skin should be protected as much as possible.
I regret not having done so when I was younger. As much as I hate sunscreen.

This makes since sense, but still feels too simplified. I used to spend many hours outside and basically developed a skin type that was easily two types higher than I have normally. When this happened, I found I could definitely do longer without a hat or other sun shades with no negative impact.

That was the first thing I wondered too. My skin is Type I or lighter going by the chart. But my neck and arms and face are much darker from a life spend outside. It says I can only go outside for seven minutes without sunscreen, which i believe if i was at the beach, but I know I can go outside much longer than that in a t-shirt without any burn.
Consider removing omega-6 seed oils from your diet. Like many others who have tried it, I now have a normal tan response, where in the past I burned in a heartbeat. Note: you do need to wait a few months for the fatty acid composition of your skin to turn over.
This is the first time I'm hearing about a link between omega-6 oils and sunburn.
Looks neat, failing on city lookup for me.
