It’s official: Mother Science is landing at Sephora—and if you haven’t heard of Malassezin yet, you’re about to.
Starting March 4 on Sephora.com and March 13 in stores nationwide, the science-forward skin-care brand will make its brick-and-mortar retail debut, bringing its full lineup of clinically proven products to one of beauty’s most coveted shelves.
Mother Science was founded in 2023 by Grammy-nominated musicians Mike Einziger (guitarist for Incubus) and violinist Ann Marie Simpson Einziger, whose curiosity about a harmless skin condition she developed on tour in 2016 led the couple to assemble a team of leading scientists and uncover Malassezin—an antioxidant ten times more powerful than vitamin C and the cornerstone of the brand.
“We are excited to partner with Sephora as our first retailer,” shares Edna Coryell, CEO of Mother Science. “This milestone represents an exciting new chapter for our brand and a meaningful step in our mission to deliver our patented breakthrough ingredient, Malassezin to the world. Expanding our presence on Sephora.com and in stores nationwide enables us to be more accessible to both our loyal following and new consumers interested in clinically proven skin care with visible results.”
Sephora is equally enthusiastic about the partnership. “Sephora is thrilled to partner with Mother Science and introduce their line of next-generation clinical skin-care products,” says Brooke Banwart, SVP Skincare Merchandising at Sephora. “We know our clients value innovative brands with intentional formulation, and Mother Science delivers on that through a science-first approach and focus on highly efficacious ingredients, including Malassezin, clinically proven to brighten the skin and deliver visible results.”
What You Can Shop

The brand’s three hero products will be available to shop on Sephora.com beginning March 4 and in stores nationwide starting March 13:
Mother Science Molecular Hero Serum ($89) is a first-of-its-kind serum that harnesses Malassezin to target dark spots and sun damage for a brighter, more youthful-looking complexion.
Mother Science Retinol Synergist ($96) pairs Malassezin and retinol together for the first time, combining wrinkle-reducing and barrier-strengthening benefits while helping to mitigate retinol’s common side effects like dryness and irritation.
Mother Science Molecular Genesis Barrier Repair Moisturizer ($68) features Malassezin alongside growth factors, peptides, squalane and hyaluronic acid to instantly repair the skin barrier and deliver visibly smoother, firmer skin.
