100% Worth a Try!
Listen to me carefully: I haven’t been this excited about a skincare product in a LONG time, and I try a lot of new products every year. I had just tried a new “viral” makeup primer that sucked every ounce of moisture out of my already dry skin in one day, ruining my skin barrier and making anything but water sting on my face, so I decided to give this a try. The consistency is light when applying, and not heavy- but you can feel that you have a protective moisturizing layer over the skin. The biggest thing? NO STINGING even on red, dry, irritated skin! Centella really is the best soothing ingredient I’ve tried. It gives a soft glow without looking oily. I haven’t had a “holy grail” product in years, until now!

Love this stuff!
Decided to give this a shot after watching one of my favorite influencers always raving about it for acne-prone, rosacea, sensitive skin people! I couldn’t be happier with it. I’m absolutely going to be reordering. It’s cooling, absorbs nicely, and my skin LOVES it! This product does not irritate my super sensitive skin, it’s a high quality product. I use this with the cleanser and the pro-bio serum both from skin 1004. They’ve all became staples in my skincare routine. Love the ingredients in these products, they’re so calming and soothing!

Day Moisturizer
I am very dry, this makes a great morning moisturizer. For the evening I do need something heavier.
