Martha Stewart, 84, renowned for her enviably smooth, radiant, and seemingly pore-free complexion, is now sharing the secret behind her glow. In 2025, Stewart launched Elm Biosciences, her skincare brand, introducing its flagship product, the A30 Elemental Serum, designed to simplify skincare routines while delivering noticeable results.
During a Zoom conversation with Stewart and cofounder Dr. Dhaval Bhanusali, the dermatologist responsible for introducing innovative ingredients like bakuchiol and exosomes to the market, Stewart revealed her motivation for creating the serum. “In my bathroom, all the shelves on one wall housed pretty much all the different kinds of wonderful skin care products… and I really wanted to simplify my daily routine,” she said.
The serum, developed after five years of research, testing, and innovation, boasts a texture that is medium-rich yet light, with a golden pearlescent hue that leaves an invisible glow on the skin. Stewart credits it with improving the texture, tightness, and overall appearance of her skin—a difference also noted by her long-time makeup artist, Daisy Toye, who has worked with Stewart daily for 15 years.
Elm Biosciences A30 Elemental Serum is priced at $135 and available at Elmbiosciences.com.
Unlike typical skincare products, A30 Elemental Serum combines recognizable actives such as bakuchiol, hyaluronic acid, and squalane with advanced compounds including acetyl zingerone, a ginger-derived antioxidant, and a patent-pending fatty acid ester designed to enhance formula efficacy. The proprietary A30 complex delivers antioxidant, anti-inflammatory, and anti-aging benefits, promising long-term improvements in hydration, pigmentation, and overall skin health.
Dr. Bhanusali emphasized the brand’s commitment to innovation: “We have the opportunity to create and engineer new ingredients, which is the basis of what we’re doing here. The goal is to…hopefully define the future of skin care.”
Alongside the serum, Elm Biosciences has also introduced an oral skin supplement. With Stewart’s track record for high-quality, critically acclaimed products, A30 Elemental Serum is expected to become a standout in the anti-aging skincare market.
