Great product
Really helps with eczema! Yes it can be a little gritty but if you use your fingers and heat it up a little the grittiness disappears.
Great item to leave in your purse, car or desk in case the eczema itch starts up.

Great for toddler eczema
Such a nice on-the-go option! We leave this in the car for quick application when my daughter’s eczema on her ankles starts acting up (she’s 2 and will scratch it while in her car seat). It helps almost instantly to minimize irritation. The consistency is smooth, doesn’t melt in the warmth, absorbs fast, and has a neutral smell. Very happy with this product and will buy more when we run out!

It's a YES. Love this stuff.
I usually don't write reviews but... this stuff is amazing for me. I don't have eczema but I needed a face lotion that didn't break me out since Iv'e been having problems with acne lately. I used this awhile ago and tried other products but nothing worked like this. It is so gentle on my face and also IT REMOVES EYE MAKEUP, which is a real game changer for me since even showering cannot take off my mascara at times. But this just swipes it away completely as well as moisturizes which is perfect. Skin feels soft and no irritations, it also lasts forever but keep it out of the heat because it will melt if it gets too hot. It is similar to stick sunscreens IMO and has a bit of a gritty texture at times but it is not abrasive and goes on smoothly. Smells like lavender but is not too overpowering of a smell. The ingredients are really clean too which is hard to find nowadays. For this price, I will be coming back from now on. This is a winner for me!

smells like lavender, but otherwise good
smells intensely of lavender, which I do *not* enjoy. it's not added just as a perfume, so they're claiming it's unscented, but the lavender smell will definitely follow you around.
texture is a little sandy and crumbly (think like a Burt's Bees chapstick texture instead of a smooth Chapstick brand one), which I actually like, it feels like it really applies well instead of just gliding on top of the skin.
smooth once it's on the skin, transfers and wipes off easily but that's expected of a balm, and it's easy to reapply. definitely a good size for the price, but the stick is so big that it's actually a little unwieldy to apply on eczema around the hands or face.
it works moderately well for my eczema patches, but honestly the lavender smell is so strong and off putting to me that I'll probably give it away anyways.

Perfect for dry, sensitive skin
I have extremely sensitive, dry skin. I also hate the feeling of oily lotion on my hands. I love using this stick so I don’t have to get the lotion on my hands and it hasn’t irritated my skin at all. It is extremely thick and sometimes hard to spread on without it being clumpy, but that’s not an issue for me.
