      Gentle and Effective Daily Lotion for Baby
      We’ve been using Eucerin Baby Body Lotion on our son every day, and it’s been very good. It keeps his skin soft, hydrated, and protected, even in the hot and humid southern weather. It absorbs quickly and isn't greasy. One of the best parts is how gentle it is, we apply it to his whole body, including his face, and even if it gets near his eyes or mouth, he doesn’t fuss or cry. It’s also pediatrician-recommended and fragrance-free, which is always a giant plus. We’ve had zero issues with irritation or dryness since switching to this, and we’ll definitely keep it as part of our daily routine. Highly recommended for any parent looking for a safe, effective, and affordable baby lotion.

      Really good baby lotion
      Recently purchased this, I was skeptical given that I’ve never used river in brand on any of my babies skin, I tried so many different baby lotions (unscented & for sensitive skin) and this one so far has been working great! It isn’t too greasy and my baby’s skin is definitely improving

      Works great for dry skin!
      I stumbled across this product when looking for a new lotion for my 2 month olds super dry skin. I tried several lotions until finally this one worked. It is fragrance free which is a huge plus. It was vent gentle on my babies skin and helped with her dry skin fairly quick. This is a staple in our nighttime routine now! Only thing I do not love about it, is that it is a little thin/liquidly which I personally don't like. Overall, great product and would re buy!

      Great Baby Lotion!
      Love this lotion for my baby. It keeps her skin soft and smooth and absorbs quickly. I even use on myself at times as well.

      Amazing for sensitive babies
      This lotion is amazing!! My baby girl has extremely sensitive skin nothing worked for her and other well known brands kept creating irritation for her. Her pediatrician recommended this brand and it truly soothes her skin with no irritation, moistures beautifully all day long and has a light refreshing scent! It’s a must have for babies that are extra sensitive! Pairs well with the body wash as well.
