Martha Stewart’s Elm Biosciences Launches Elemental Lip Serum

Martha Stewart’s Elm Biosciences launched Elemental Lip Serum on September 22, a peptide-powered balm-oil hybrid aimed at visible signs of lip aging while delivering hydration, shine, and sheer tint, USA Today reported. The treatment retails for $45, launched with a promotional $36 price in USA Today’s coverage, and arrives in four shades: Blush, Petal, Mocha, and Clear.

Co-founded by Stewart and board-certified dermatologist Dr. Dhaval Bhanusali, Elm Biosciences positions the serum as skincare for the mouth rather than a simple gloss. USA Today lists claimed benefits that include fuller-looking lips, smoother vertical lip lines, lasting hydration, improved softness and texture, barrier support, and a sheer wash of buildable color. The formula blends peptides, antioxidants, shea butter, squalane, and a deep hydration complex, according to the brand’s briefing to the outlet.

Page Six published same-day exclusive comments from Stewart, who said the serum “genuinely transformed” her lips, calling them softer, fuller, and healthier-looking than they had been in decades and stressing clinical testing over “wishful thinking.” Page Six also reported an intimate Manhattan breakfast launch earlier in the month where Stewart said fans had been asking about the product after spotting it in her selfies.

USA Today cited a dermatologist-supervised perception study of 54 women who used the product for seven days. After one week, 100 percent reported lips that felt hydrated, 98 percent reported softer lips, and 89 percent reported healthier-looking lips. Individual results vary, but the study language underscores Elm’s attempt to market the serum as a treatment-adjacent hybrid rather than seasonal color cosmetics alone.

Shade storytelling is deliberately wearable. Blush is described as a warm toasted peach, Petal as a soft neutral rose, Mocha as a rich chocolate brown, and Clear as color-free shine and hydration. Page Six’s editors highlighted Blush as a favorite in early wear tests and praised the applicator’s cooling effect, packaging detail, and all-day comfort—notes that matter for a brand that sells Martha Stewart’s reputation for meticulous product finishing as hard as it sells peptides.

Elm Biosciences launched in 2025 with A30 Elemental Serum and Inner Dose Daily Skin Supplement before adding A30 Elemental Night Cream. The lip serum extends that lineup into a category beauty editors often call overlooked: aging lips that crack, thin, and line while the rest of a routine gets active serums and retinoids. Stewart and Bhanusali have repeatedly framed the company as biotech-informed rather than purely celebrity-endorsed, pointing to a network of more than 350 dermatologists, scientists, and researchers informing development, per USA Today.

Commercially, a $45 lip treatment sits in prestige-accessible territory—above drugstore balms, below ultra-luxury couture glosses—and the launch-day sale price softens the entry for Stewart’s broad fan base. Availability through the Elm Biosciences site and dermatology partners, as noted in USA Today’s shopping package, suggests a direct-to-consumer and clinic hybrid path rather than an immediate mass-retail flood, though Page Six’s commerce desk already treated the drop as a same-day shoppable story.

For lifestyle readers, the news is less about a single selfie product than about how legacy lifestyle figures are building science-forward skincare brands that still trade on personal testimony. Stewart’s quote to Page Six does classic founder marketing; USA Today’s clinical percentages and ingredient list do the efficacy framing. Together they give Elemental Lip Serum a clear September 22 launch narrative: a longevity-minded lip serum from Elm Biosciences, four wearable shades, a $45 retail tag, and a celebrity-dermatologist partnership betting that lips deserve the same actives conversation as the rest of the face.

Stewart’s longevity pitch also fits a broader 2026 beauty trend in which heritage personalities pair with clinicians to sell actives in unexpected formats. A lip serum with peptides and squalane borrows the language of facial serums while keeping the swipe-and-go ritual of a gloss, a hybrid that USA Today and Page Six both framed as the product’s commercial logic. For readers who already own Elm’s A30 serums, the lip launch is a logical add-on; for newcomers, Stewart’s personal claim and the seven-day perception study are the on-ramps.

Price architecture will shape early sell-through. At $45 full retail, Elemental Lip Serum competes with prestige treatment balms; the launch-day $36 offer, flagged by USA Today, widens the funnel for Stewart’s mainstream audience without permanently repositioning the brand as mass. Page Six’s early wear notes—cooling applicator, flattering tints, overnight residue that signals lasting treatment—will likely circulate in affiliate and social commerce posts through the first week, amplifying the September 22 street date beyond traditional print beauty pages.
