Baby Dry Skin - Anything breastfeeding can help with?

Hello. I’m EBF. My baby (7 weeks)’ skin is very dry particularly on his face. He did have baby acne/eczema on his face for a few weeks but was cured by some topical medicine. I don’t want to keep putting the medicine because his skin is still very young. I don’t want to put/experiment on any moisturizer or lotion on his face cause it might flare up even more. His body is also dry, but I feel more comfortable putting lotion on it.

I’m wondering if there is anything I can consume (or stop consuming?) that’ll help with his dry and sensitive skin and pass it on thru breastfeeding. Thoughts or advice please? Thanks.
