Hydrating Itch Relief for Sensitive, Reactive Skin
I recently dealt with an allergic reaction that left me with red, intensely itchy hives across my body. Medication helped calm most of the symptoms, but this itch relief balm from Aveeno made a noticeable difference in soothing the lingering itch and rehydrating my irritated skin. The formula is very concentrated, so only a small amount is needed to cover a large area, and it begins to work quickly. There is no added fragrance, which is ideal when your skin is already reactive and sensitive.
The jar is generously sized, and the wide opening makes it easy to dip your fingertips in and smooth the balm over affected areas without fuss. The texture spreads well, absorbs cleanly, and leaves the skin feeling comforted rather than coated. I found it especially helpful during the recovery phase when my skin still felt dry and unsettled. Definitely recommend for anyone dealing with post‑reaction itch or general irritation.

Really good eczema lotion for 4 month old baby
Love this lotion. I’ve been using it for almost two weeks now on my baby who has eczema, I didn’t wanna waste money on the baby version because what if it isn’t as powerful so I got this one and now my baby’s cheeks aren’t red and spotty. Honestly didn’t think it would work but it’s working great, I add it all over his body especially his face after he showers and it helps his itchiness at night. During the day I add some if the redness looks like it’s coming back and it ends up going away mid day. I’ve used about 4-5 other lotions that didn’t work so I’m very happy about this one.

LOVE THIS!
I have allergies and overall just super sensitive skin. Sometimes I just randomly get itchy or get hives. I bought this during a time I was trying all the lotions just to find something that would help.
To be honest, I shower in the morning and apply this and it helped my skin tremendously. I wouldn’t be itchy after showers. Hives were few and far between.

AMAZING! Works better than my RX
After being prescribed hydrocortisone 2.5% to help with my eczema I felt it wasn't doing enough. Healing time was slow and the scaling itching was still bad at night. I don't know why it took me so long to try the Aveeno Eczema line, I really wish I did sooner. This product is AMAZING! I started using this twice a day AM/PM after washing my face with cold water only and stopped using the hydrocortisone completely. My skin healed in 5 days!

Aveeno Eczema nighttime balm
I love Aveeno. This is my first purchase of the Eczema nighttime balm. It is super thick. It feels like Vaseline. It does feel greasy after you put it on. Obviously it is for eczema so it has to be moisturizing. I do have eczema. Aveeno lotions imo do not feel greasy after you apply which is why I love their lotions. This balm is definitely perfect for applying at nighttime to help heal your skin while you have some down time. My skin always splits due to extremely dry skin even though I use lotions every time I wash my hands and after showers. This would be perfect after a shower to lock in the moisture. I would definitely recommend. I use the silicone “socks” at night when my feet are in need of moisture. This would be perfect to use before putting on the silicone socks. The silicone socks do feel like chicken cutlets being put on your feet but in the morning when you take them off my feet are so soft and smooth. I can turn the jar upside down and it didn’t move, that’s how thick it is. I will purchase again.
