Absolutely worth the money!!
I'm 38 and I've never had eczema but I did always have sensitive skin. About a week ago I noticed a dry patch under my eyelid and boy did it flare up very quickly. I tried several plant based products for eczema but it just burned. I decided this product would be my final purchase before going to urgent care.
I received this product 2 days ago. After reading the reviews I decided to slowly add this to my skin. Now it did burn on the part that was super worse than the other so I made sure to put very thin amounts till my skin could handle a thick application. Id say I put the cream on about 6times the first day by the next day I could already see the difference the swelling and redness went away. The second day I did the same no more slight burning my skin is still dry but it is healing.
I would definitely give it a try if you're experiencing eczema for your first time!

Itch-Free Face :)
This cream made a difference day one! It soothed the skin around my eyes and eyelids plus on my face. I forgot to wash my face one night and my skin was still outbreak free and felt so smooth. I haven't had itchy skin since I started using this cream. I would definitely recommend to a friend.

Ouch! I paid WHAT for this?
This "eczema cream" contains alcohol. It says you can use it on your face and body. I applied the cream to my face and it burned my eyes. I then read that the ingredients contain alcohol. It did NOT help with my eczema at all. Everyone's skin is different, but I personally was very disappointed especially at $20 for 2oz. that the product ingredients were not soothing, burned my eyes, and dried out my skin more than it already was.

Eczema Relief! Everyday use
Wow. I have been struggling with eczema / red rashes around my eyes on and off for over a year. Its gotten really bad as the cold weather in Chicago has irritated my skin really bad. After one use of this brand, my eyelid skin is already recovering. I tried the ointment first and then the cream version as well. I find the ointment works best overnight for me and the cream is a good morning option, as i do like to wear makeup most days. Im definitely going to start using the cream as part of my everyday skincare routine. My concealer lays over it so perfectly and theres NO patchiness and NO flakes. The ointment and cream of this brand is so good at disguising the dryness and relieving the redness. I can’t believe I didn’t find this sooner its so inexpensive and works so well. I have such sensitive skin and am very hesitant when trying new products. If you’re undecided on this product, give it a try. This is definitely a repeat purchase of mine.
