If there’s one person whose skincare routine deserves our attention, it’s probably Martha Stewart. The lifestyle mogul has spent decades teaching us how to set a table, decorate a home, and roast the perfect chicken. And, considering her famously radiant complexion at 84, she may have accidentally become one of beauty’s most convincing ambassadors too. After five years of development alongside board-certified dermatologist Dr. Dhaval Bhanusali, Stewart launched Elm Biosciences in late 2025. Nearly a year later, the biotech-driven brand’s hero product (the A3O Elemental Serum) has already established itself as a favorite among beauty editors and skincare devotees alike.
The $135 serum is powered by the brand’s patent-pending A3O Complex, an antioxidant designed to target UV damage, discoloration, dehydration, and irritation. It’s formulated as a gentler, more stable alternative to traditional vitamin C, making it a game-changer for sensitive skin. The formula is also infused with line-smoothing hyaluronic acid to lock in hydration, squalane to support the skin barrier, vitamin E to soothe, and blue tansy to help lift redness and discoloration.

According to editors and reviewers, the texture is just as impressive as the ingredient list. The lightweight serum sinks in almost instantly without leaving behind a sticky finish, making it easy to layer under sunscreen and makeup (a rarity for vitamin C serums).
There’s no shortage of celebrity-backed beauty brands on the market these days, but Stewart’s Elm Biosciences feels substance-over-star-power. Rather than relying on her name alone, the brand has built its debut around an innovative formula that delivers real skincare benefits. At $135, it’s certainly a splurge, but if looking even a little more like Martha Stewart is the goal, this serum might be money well spent.
