Really helps soothe baby eczema overnight
Size: 11 Ounce (Pack of 1)
This balm worked very well for my baby’s eczema, especially when used at night. It’s thick and moisturizing but not greasy, and it absorbs nicely into the skin. After a few nights of use, I noticed less redness, dryness, and scratching, and my baby seemed more comfortable sleeping.
It’s fragrance-free and gentle, which is very important for sensitive baby skin. A little goes a long way, so the jar lasts a good amount of time. If your baby has dry or eczema-prone skin, this is definitely worth trying.

Helped with my baby's eczema!!
Size: 11 Ounce (Pack of 1)
Long overdue review but this was a lifesaver for my sons eczema. Before he was diagnosed, I was struggling to find a moisturizer to help soothe his angry red skin and his flare up wasn't going away or lessening at all. My sister whose son also has eczema, suggested I buy this tub after she gave us some to try. It worked! As a first time mom, seeing my 4-5 month old baby suffering from itchy and uncomfortable skin, I was so stressed about finding something that would help him. This body balm was thick and applied daily after his nighttime bath. The large red patches on his body slowly started to dissipate and we were so relieved. He was prescribed steroid cream for worse flare ups but we use this regularly to keep his eczema flare ups to a minimum and avoid steroid use as much as possible. Although sometimes this doesn't work for the more severe flares, so keep that in mind. It's okay to use the steroid cream or eucrisa prescribed by the doctor. Aveeno is a great daily maintenance cream to help keep their skin moisturized and happy. I highly recommend this jar of body balm, it lasts for many months and a little bit goes a long way.

Very gentle and effective for baby’s eczema-prone skin
Size: 1 Ounce (Pack of 1), Size: 1 Ounce (Pack of 1)
This Aveeno baby face cream has worked really well for my baby’s sensitive, eczema-prone skin. I use it daily on the face, especially on dry and irritated areas, and it helps keep the skin soft, calm, and well moisturized.
The texture is rich but not greasy, and it absorbs nicely without leaving the skin sticky. I’ve noticed a clear improvement in dryness and redness after consistent use, especially during colder or drier days.
I appreciate that it’s gentle, fragrance-free, and suitable for delicate baby skin. It hasn’t caused any irritation or breakouts, which gives me peace of mind when applying it to my baby’s face.
A small amount goes a long way, making it great for everyday use. Overall, this is a reliable and soothing face cream for babies who struggle with dryness or eczema. I would definitely recommend it to other parents.
