Mother Science launched a clinical skincare at Sephora, introducing the 'Malassezin' line, an antioxidant the brand says is markedly stronger than vitamin C. The collection arrived online March 4 and hit Sephora stores March 13, 2026, bringing the label’s lab-developed formulas to mainstream retail. The brand was founded in 2023 by musicians Mike Einziger and Ann Marie Simpson Einziger and developed alongside a team of scientists to commercialize the patented ingredient.
The Sephora assortment comprises three core SKUs: 'Molecular Hero Serum,' 'Retinol Synergist' and 'Molecular Genesis Barrier Repair Moisturizer,' with formulations that pair Malassezin with retinol, peptides, hyaluronic acid and squalane. Pricing ranges from $68 to $96 and emphasizes clinical efficacy and barrier support over solely cosmetic claims. Sephora framed the launch as an expansion of its science-led skincare assortment.
For shoppers, the debut makes a lab-centric ingredient accessible through a major retailer, easing discovery and sampling. The line aims to address discoloration, retinol tolerance and barrier repair, fitting a broader trend toward clinically validated actives in prestige beauty.
