I thought "sensitive skin" meant skin that is prone to redness, irritation, breakouts, etc. Isn't that why those type of products are formulated without fragrance, harsher surfactants, and so forth?
When you apply this citric acid solution to your face, do you wash it off after a certain time, or does it self-neutralize when your skin returns to its original PH after an hour or so? Wouldn't it technically be an AHA then?
I'm using citric acid + sodium citrate to buffer urea. I added too much citric acid the PH went down to 5-5.5. So then I added the citrate to get it up to 6. I don't know if that's the way to do it. I've never come across documentation explaining ho…
If using a buffer of citric acid and sodium citrate, what is the typical ratio?
Would you just add the two ingredients until the desired PH is achieved? Or should they be premixed and then added?
How come microneedling isn't foolproof then?
But getting back to the original question...would a cut over a wrinkle conceivably get rid of it? I would assume all the tissue in that spot would be regenerated.

The sun does have few other alleged benefits but they aren't for skin, and the sunlight need not be direct. For example, sunlight helps regulate circadian rhythm. That may have something to do with the indoor/outdoor energy thing…
Vitamin D doesn't have to come from the sun. You can get it through a multivitamin or fortified foods as Perry said. Even milk has some Vitamin D.
I've read that Vitamin D can't pass through windows. You have to be outside to get i…
