Great ingredients - very strong scent
Size: 16 Fl Oz (Pack of 1)
I have really dry skin and frequent eczema so ordered this lotion to try out. I use a standard colloidal oatmeal lotion typically and it's hard to find a good lotion that doesn't have petrolatum. This one uses olive and jojoba oils instead. I ran it through a product safety app and it scored a 93/100 which is REALLY good for an eczema lotion - the only potential problematic ingredient is peppermint leaf which can be an allergen for some folks. It comes with a pump for easy use and I didn't find the lotion too greasy or oily - it seemed to absorb well. My only problem with the lotion is how strong the tea tree oil scent is - I use eczema lotion at bedtime and the smell was so strong, it was keeping me awake. If you're sensitive to tea tree oil, that could be an issue. But it's great for daytime use and has a nice, fresh scent. It's preventing the dryness and cracking on my hands that typically happens with "normal" lotions so the oat kernel flour is doing its job. As long as you don't have an aversion to a strong tea tree oil scent, this is a perfect eczema lotion. I've only ever found a handful of them that don't use petrolatum and I appreciate that this one uses plant oils instead. It works to keep the hands from drying or cracking. The price tag is on point with the other eczema lotion I use with it currently being $21 for 16 oz. Definitely recommend this if you are looking for an ingredient-safe eczema lotion.

Best hand cream for extreme rough hands
Size: 16 Fl Oz (Pack of 1)
My husband struggles with really rough hands and it's the best thing we've found. It does have a bit of a medicinal smell, but well worth it for the relief! Highly recommend.

Smells like a disinfectant
Size: 16 Fl Oz (Pack of 1)
I’ve been struggling with eczema terribly this winter, scratching to the point of bruising. Nothing seems to help so I figured I’d give this a try. I will say that it does provide instant relief, but it is short lived and not worth the scent. It smells terrible and reminds me of old fashion Pine Sol. I think there are better products out there. I wouldn’t buy this again.
