My youngest's lips are very dry and chapped, and regular lip balm isn't helping. What should I use?…

Maybe a lipstick or cream with lanolin?

Methyluracil

Lanolin
Morozko cream

I applied Purelan to myself

Buy vitamin A at the pharmacy. It comes in liquid form or capsules (you can prick the capsule and squeeze it out). It's also in healing creams everywhere.

Lip balm helps a lot

Dexpanthenol at night
and Aevit capsules (looks like fish oil) I just squeeze out the liquid and apply it a few times a day

Acriderm

with liquid honey at night

Vitamin A and E. I squeeze the capsule and apply it at night. It all goes away by morning.

Lanolin helps a lot.

Suhareva Olga I second that, it heals great (just don't read the instructions)))
