Definitely works!
I noticed I was having weird rough patches on my back and thighs but didn't know what they were. So with my next appt to the dermatologist, I found out it was eczema. Ugh. So I started looking at creams and such and stumbled on this bar soap. It works really well. When I shower, I work it into the problem areas and let it sit there with the shower head turned away so it doesn't wash off, and then wash my face, etc. When I'm finished with everything, I wash everything off, after the soap has been on my skin for several minutes. I've noticed a substantial decrease in the bumpy areas on my back and legs. I loooove this soap, and yes, definitely recommend it for people dealing with eczema. But definitely use an exzema skin cream too if you are itching. I wasnt, but started to as well because it also helps to keep the outbreak under control as well.

Soap for dry skin on the face and body
This soap does soften the skin of the affected area but the itching still continues. I am not sure if there is an anti itch ingredient in the soap but there should be.

Great sunscreen!
Style: 4 Fl Oz (Pack of 1)
Eucerin Sunscreen works well and applies cleanly, not greasy. I spend a lot off time outdoors and I am satisfied with the sun protection this product provides.

Don’t rub, break it down between your fingers and dab!!
Style: 4 Fl Oz (Pack of 1)
Great sunscreen. The first time I applied it, i made the mistake of rubbing it in so it gave me a white cast. I learned my mistake the second time, spreading it in between my fingers and than dabbing it on my face, it gives a cast at first but after a few minutes it went away. And it feels so good. like I’m not wearing anything. I tried the tinted sunscreen it feels good but it made me look orange. I used to wear the Eucerin Daily Lotion spf 30 but they discontinued so I had to look for a replacement and after trying other sunscreens they were all terrible; greasy, allergic reactions and too creamy! This one’s perfect, it’s definitely my new go to!!

The Only SPF My Skin Will Tolerate!
Style: 4 Fl Oz (Pack of 1)
After 20 rounds of radiation, I was given a list of exactly four things I could put on my face--things like water and Vaseline. Of course, I was also instructed to wear SPF in "all visible light." However, finding a sunscreen my skin could tolerate proved to be a challenge, as even those made with clean ingredients, marketed for babies, and/ or claiming to be hypoallergenic resulted in hot, angry rashes. Price point also didn't matter; I tried everything from drugstore to premium brands.
Thankfully, when this product came on the market, my dermatologist suggested I try it. I've been wearing it ever since. It IS thick so I usually rub any remaining face moisturizer into my palms and then add the Sunscreen, rubbing and warming it between my palms to make it more easily spreadable. Then I press it onto the skin on my face with my palms and fingers--I don't like to pull or tug too much at the skin on my face. At first, there is a visible white cast, but it disappears within a couple of minutes.
If I'm really in a hurry, now I can mix a tiny bit of my foundation into the sunscreen so that it spreads faster and I can move on from the white cast faster--I know I lose some sun protection factor that way, but my derm says I also gain some protection in the tinting, so it's okay. The important thing is that I get it on in whatever time I have.
I'm just grateful to have found something that doesn't upset my crazy-sensitive skin! Wishing all you sensitive beauties protected fun in the sun...
