“The reason we didn’t launch this earlier is because alternative ingredients just were not available,” she says. True to her brand’s strict “no” ingredient list, she sought to avoid a formula built around silicones, talc, PEGs, synthetic fragrances, and other agents that give many traditional foundations their extended, filter-like wear. Eventually, she found a few miracle swaps. Here, she traded silicones for coconut alkane (known to deliver a smooth, silky feel) and amino acid filling powders to blur and absorb excess oil without drying out skin (or, worse, clinging to dry patches).
While blurring has turned into a 2026 cosmetic buzzword, finish has always been integral to Westman’s skin philosophy. “Blurring is a play on light and texture,” she explains. By making pores appear smoother and diffusing the light in a particular way, the amino acid powders give a filter-like effect while letting the natural skin shine through.
Biocompatible amino acid–derived treatment pigments are another one of the formula’s breakthrough ingredients. The technology gives each shade a flexible quality that melds color onto the skin with ease. As you apply the thin foundation on skin, you’ll notice it blends like a serum-cream. Dispense one drop on the back of your hand and start blending, with a brush or your fingertips, at the center of the face moving outward. Remember: A little goes a long way.
Once satisfied with the formula’s wear, she turned to the skin care inside. For this, the team entrusted a Spanish biotech lab known for its active ingredients and skin-care delivery systems. The formula leads with a peptide complex that targets skin’s elasticity, collagen stimulation, and skin renewal—encapsulated in exosome technolgy that delivers the ingredients where they need to go. Then there’s vitamin B3 for brightening and a trio of botanical extracts to support the skin barrier.
“I’m always thinking about how I can maximize my skin-care routine,” she adds. Helping someone be more cognizant of what they’re putting on their face is a true luxury: “Quality is something that’s addressing more things than just the superficial cosmetic aspect of a foundation. There’s not one single compromise here.”
Lightweight, serum-like, pore refining, and backed by innovative technology and sustainably sourced ingredients, Suprême Bio-Complex Liquid Foundation is certainly Westman’s dream realized. “I think this is the proudest I’ve ever been of a product—without comparison,” she says. “If it weren’t mine, I would be blown away.”
