My son is 5years old. He has extreme dry skin , sometimes it bleeds. Seeking medical attention too ,any other recommendation?

Consult doctor.

Apply virgin coconut oil 30 min before bathing.

Use very mild soap or apply besan with turmeric and curd.

If it is tooo much consult doctor,use coconut oil twice or thrice a day,and try using Bioderma Atoderm soap as for my baby extreme dry skin he asked me to use Bioderma Atoderm soap it makes skin smooth

For extreme dry skin you can try Bioderma Atoderm soap, it's a fragrance free soap and effective for this winter.

If it is too much then consult with your doctor. And it's winter time so dry skin will be there. Apply 3-4 times ghee to reduce dry skin problem fast. For future to avoid dry skin always massage before bath and apply lotion after bath. This will help you. As per my personal experience I would suggest you to use mamaerth moisturising body lotion. A natural and non sticky lotion that helps to keep skin soft and moisturised without any dryness. Its fragrance is also pleasant.

Consult your doctor for a good lotion to cure dry skin. Also give ghee and butter to eat in food. Try to avoid soap in winters as it may make skin more rough or dry. So its better to go for body wash. I am using mamaerth body wash for my son. It is a natural dermatologically tested product that keeps skin soft and smooth without any dryness.
