Please keep the caveats

The answers describe everyday, over-the-counter use on healthy adult skin. They are not medical advice, and a prescriber's directions always come first. A "Yes, with care" means something different without its care note, so keep them together. If you spot a mistake, email [email protected] and we will fix the page and the shared copy.
