Hello R.,
My 7 year old has/had eczema. I've used Arbonne's baby line on her. I have her put it on her face everyday and it works wonders. I LOVE it. Arbonne also has lip service for the lips. One of the little girls at my daughter's school has eczema and her lips were horrible (worse I'd EVER seen) so I got this product for her and it has helped her so much.
I'm thinking the reason he's licking his lips and around his lips is because the moisture makes them feel better. I could be wrong as I'm not a dr.
I do have a sample of the baby products if you'd like to try them. Please let me know.
A little about Arbonne's product no animal products or by-products (Vegan certified), dermatologist tested, baby products are peditrician tested, hypoallergenic, never tested on animals, ph correct, botanically based and contains no mineral oil.
Hope this information helps.
Take care and God bless!
M.
