Here's Why Josie Maran's Newest Serums Might Be More Powerful Than Other Ones in Your Collection

Argan oil is loaded with skin-repairing vitamin E, antioxidants, and essential fatty acids, which is why Josie Maran had made it the key ingredient in 90 percent of her eponymous beauty line. Now, her brand is swirling the ingredient into two new skincare products: Argan Bright Skin Vitamin C Serum ($65) and Smooth Skin Resurfacing Serum ($70).

While each one is moisturizing, they target separate skin concerns. The Argan Bright Skin Vitamin C Serum uses vitamin C and licorice root to brighten your complexion and reduce the appearance of dark spots, while the Smooth Skin Resurfacing Serum uses lactic acid to gently exfoliate the skin and refine its texture.

Cosmetic chemist Ginger King said these serums are more like lightweight facial oils, which have a key benefit over water-based serums. "Oil-based products can be more potent than water-based ones," she said.

Maran had that in mind while formulating her serums. "[Water-based] actives don't last long on skin," she said. "If you think about it, water evaporates almost immediately on your skin. And with the evaporated water, the ingredient potency and activity also fades away. Oils don't evaporate, and because argan oil is identical to our own skin's composition, the actives are readily accepted. Your skin recognizes it, and it's able to go right to work."

If you're apprehensive about using oils because they tend to sit on your skin, don't be — at least not with Josie Maran's latest products. Each one quickly absorbs and leaves only a hint of shine behind.

Ahead, check out the new serums, which will be available at Sephora on July 8.
