Packed full of amazing ingredients!
This is one of my favorite serums for aiding in skin barrier health. The ingredient list is really impressive, but some stand outs that my skin just loves would be the ceramides, peptides, niacinamide, oatmeal extract, algae extract, cholesterol, and squalane (plus much more!). The consistency of this serum is on the thicker side, which I prefer to more watery Show more
I am on my second bottle of this. I bought it for the hydration and I have not been disappointed. This, along with Centella products and double moisturising at night have made a big difference in the hydration of my mature, dry skin. I can see this being a permanent fixture in my am routine.
