Dry itchy skin

Fiorella • Soon to be mom of 2

So my baby suffers from ezcema. Now i have tried almost everything, breast milk soap, sensitive soap, cerave ointment, aquafor, hydrocortizone and he just keeps scratching. Specifically his neck, chest and thighs. My question is can I put vitamin e oil directly on my baby skin. He’s 8 months old.
