@Alfred Thank you.
@piquant00 If the caffeine were dissolved in DMSO first it would probably penetrate the skin. (NOTE: I do not recommend trying this.)
@piquant00 @Alfred I’m wearing a little estrogen patch on my skin, so human skin can absorb estrogen. I have no idea about caffeine, though.
@LindaGoodliffe Alfred says no. 🤷♀️
@piquant00 @Alfred
Can Alfred be wrong? Because I have wrinkle cream that's basically pure caffeine, and it does temporarily smooth out wrinkles.
@piquant00 No, caffeine molecules cannot be absorbed through human skin.
