Advice for my mother’s hands

Hi all! I hope this is okay to post here, and maybe some of you can advice.

My mom has been a vet for 35 years, she owns her own clinic and works way too much, which impacts her health.

One of these health problems is her hands : she washes them all day everyday, wears latex gloves… and with winter coming she gets these terrible crevices on her fingers… They hurt a lot, I’ve bought her hydrating creams and gels, she wears gloves at all times but nothing really helps.

Have some of you experienced this? Could you recommend something that would prevent this from happening?

Thanks a lot!
