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.

In most of all circumstances, this works
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
For Summer time and when playing and working in the sun, this is my go to sunscreen! I love how it is more natural than all the other ones out there. I have been sort of a spray on sunscreen connoisseur and this is the one that is my favorite. Also, if I have gotten a burn and put this on it, I believe it helps start the healing process on the burn I got. This is at least what I experienced multiple times last year.
The only circumstance that this sunscreen fails miserably is in the Caribbean. I recently went on a cruise to that region and applied this sunscreen and it became evident that this and the other brands of spray on sunscreen do not work in Caribbean sun. The only sunscreen that works is the lotion based stuff that you rub into your skin. I have also consulted with friends on spray on sunscreen in the Caribbean and they all fail as well.
So, this is why I say that it works in almost every circumstance.

spray nozzle needs work.
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I purchased 3 of these cans. Only one of them worked and that one was ok. Sprayed well, smelled good and and protected my skin and even though it was hard to press it to work, we WERE able to use it, but the other three .............? They would not rotate to the unlock position, therefore they would not spray. My husband and I tried everything to get it to rotate. It seems both the top and bottom ring spin around effectively doing nothing. So to pay almost $40 for only one can to work is definitley not worth the money. Buy somewhere else.
