OBSESSED
Hi there! I’ve been using Puriya’s “Mother of All Creams” and “Wonder Balm” for years. Even did a podcast episode talking about Mother Of All Creams! Best moisturizer EVER. I’ve referred over 50 people to Puriya products. No joke! When “Free To Be Me” supplements launched— I instantly bought them to try. I’ve only been using them for 2 weeks but notice a huge difference in my skin! My skin isn’t red at all, and my dryness down like you wouldn’t believe. Honestly, I’m GLOWING. BUY THESE. Affordable and 100% worth the money.

Amazing Cream! Like Magic for Me!
Somehow I triggered an eczema flare, and this time it hit my face. I had little bumps everywhere, my skin felt extremely dry and painful, and even under my eyebrows was sore. I’d only ever used eczema creams for my body, so I had nothing meant for my face. I searched for a facial option and this had great reviews and photos that made it look like it worked almost instantly. It arrived in one day, and I used it that night. The cream is very smooth, creamy, and incredibly soothing. By the next morning, my face was back to normal. It did sting slightly when I applied it, but only because my skin was so irritated, not because of any harsh ingredients. The relief was almost immediate. My skin felt soft, smooth, and calm again, and all the irritation cleared up like it was never there. It has a pleasant scent and is very moisturizing. Honestly, it felt like magic. This was a true lifesaver in the moment, definitely a face saver. It isn’t inexpensive but at the moment anything that worked would’ve been worth the price. I highly recommend it.

Love This Stuff!
I have skin allergies to anything with fragrance, so I get a lot of eczema flare ups. Not only does this not cause flare ups, but it helps soothe any irritation I have on my face. It’s also not too heavy and doesn’t leave a film feeling or cause breakouts like a lot of the other creams I’ve tried with colloidal oatmeal. Really love that they were able to work such a helpful, soothing ingredient into such a nice formula!

Burns
Maybe once you get your eczema under control with some other product, you can use this for maintenance, but it's an absolute misery if you have a bad outbreak of eczema. I have no idea why this thing has alcohol in it but it burns like a star when you put it on severely irritated skin. Note: I originally gave this 3 stars, but Eczema Honey reached out to me to offer a refund. I didn't take it, but I appreciated that they *would* do that. Plus, my acute outbreak has subsided and it's perfectly fine to use now, so just be warned it hurts to apply if you have an active eczema flareup!
