Pump stops working
I love this primer and color however the last 2 bottles I have gotten the pump stops working with the container still at least half full. I have to take the entire top off to get to the primer.

Soothes dry, eczema prone skin
Size: 1 Fl Oz (Pack of 1)
My son has moderate eczema and it seems to really flare up when his skin is dry. We started to use this as a final step in his bath time routine and I’ve noticed a pretty big difference in his skin. I usually wash him off with soap, then put this on to sink in for the remainder of his bath and rinse off right at the end. When I don’t use it I notice his skin is drier and more itchy. It is a staple in our bath time routine!

Gentle and works well
Size: 1 Fl Oz (Pack of 1)
We really like this! It’s gentle on my daughter’s skin and hasn’t caused any irritation. It lathers nicely without being harsh and leaves her skin feeling clean and soft. A great option if you’re dealing with sensitive or eczema-prone skin.

AMAZING so far!!!
Size: 1 Fl Oz (Pack of 1), Size: 1 Fl Oz (Pack of 1)
So far so good! Bought this out of desperation my poor bub was suffering with red itchy eczema so bad and bathing her resulted in painful stinging and screaming. Last night I used this cream wash in a lukewarm bath about 96 degrees and quickly and gently wash her entire body no more than 10 minute bath since we have extremely hard water…I then SMOTHERED her in baby advanced therapy aquaphor before putting her onesie on and the next morning her skin looked so much better. The ingredients aren’t totally great and is why I hesitated to purchase at first but it ended up being fine. Very creamy and moisturizing, does not have suds at all which is what eczema needs. No smell to it which is good cause she’s very sensitive to fragrance. Big bottle for the price. I would recommend giving it a try, every baby is different but if you’re desperate like I was it can’t hurt to give it a shot. I have attached a before and after picture of her belly, first was before the bath and second is the morning after.
