Sunblock recommendations (that don’t discolor skin)?
Last year, our toddlers cheeks got discolored and I think (could be wrong) it was the sunblock he was using. The melatonin got reduced in splotches (skin whiter).
What are your sun block recommendations to avoid skin discoloration issues?
Discoloration isn’t nearly the issue than the toxicity of so many commercial sunblocks that penetrates the skin and lasts for a long time. Last I looked at the more natural options they tended to be somewhat abrasive, or annoying like zinc oxide. You would need to check around for yourself.
The point I wanted to make was that consistent exposure to early and late day sun can help build up a “sun callus” which will help prevent burning. Even in very light skinned people. The sun is actually your friend. Metanalyses prove that. So long as you don’t burn, which I realize is a major concern for our youngsters. You want as much sun on as much skin as much of the time throughout the day as possible. It’s how we evolved. It’s how most of our hormones work. Starting with light penetration of our opsins, like melanopsin. At different times of the day, starting at dawn. As much as you can – no sunblock (aside from visers or clothes or shade) and no sunglasses (because it distorts the wavelengths that enter the opsins in your eyes).
I recommend Dr. Jack Kruse and Dr. Leland Stillman on these issues. We are foremost biophysical beings, more so than biochemical. As Dr. Zach Bush likes to point out, physicians aren’t comfortable with physics. If they were they would go into engineering instead. So they aren’t instructed in biophysics in medical school and tend to completely ignore it.
I don’t have any particular recommendation, but I generally refer to the Environmental Working Group for stuff like this. They publish guides for things like sunscreens, bug sprays, household cleaners, etc.
No idea on the splotches/skin discoloration. They do some deep dives on different chemicals in them, and definitely have some reservations about the common ingredients, especially for kids.
Here is a link to their baby/kid recommendations:
You have to flip it over and read the active ingredients because they change their formulas and/or packaging year to year.
I’ve always been a put my head in the water swimmer (open my eyes underwater too). I was not a big sunscreen person for swimming, until I had kids. The first time I used regular sunscreen and a bunch ran into my eyes when I came back up from under water it stung like crazy. If you ever watch a kid screaming after being dunked, consider that it might be the sunscreen.
So I marched off to Target, stood by the sunscreen display, read the active ingredient labels and proceeded to rub a little bit of each in my eye.
To this day I use titanium dioxide on my face. Zinc oxide seems to be good too. Just for ease I use the spray for the rest of my body.
