The brand officially launched on September 17, 2025, after the company says five years of development. Its original release featured the A3O™ Elemental Serum and Inner Dose Daily Skin Supplement; a night cream arrived in January 2026, and later coverage reported an Elemental Lip Serum.
What is Martha Stewart’s new skin-care line called?
The line is called Elm Biosciences. Stewart developed it with Dr. Dhaval Bhanusali, a board-certified dermatologist. Elm says its advisory board includes more than 350 dermatologists, scientists and medical researchers, and describes its products as using a “dual-pathway” approach aimed at both internal and external factors associated with skin aging. Those development and advisory-board statements are claims from the company’s launch materials, not independently audited findings.
In the launch release, Stewart said she had used the products through their developmental iterations for five years and was pleased with the results. That is her personal statement; it is not an independent clinical evaluation.
Which products are in the line?
| Product | Format and timing | Positioning described in available coverage | Published price |
|---|---|---|---|
| A3O™ Elemental Serum | Topical daytime serum | Patent-pending antioxidant serum with the A3O Complex, positioned for the appearance of UV-related damage, pigmentation, dehydration and irritation, including on sensitive skin | $135 suggested retail price, according to Elm Biosciences’ 2025 launch information |
| Inner Dose Daily Skin Supplement | Daily ingestible capsule | Dermatologist-formulated supplement positioned around internal factors such as inflammation, oxidative stress and hormonal imbalance | Not stated in the cited launch material |
| A3O Elemental Night Cream | Topical nighttime treatment | January 2026 coverage describes a retinoid derivative combined with the A3O complex, ectoin and peptides for restorative overnight care | Not stated in the cited coverage |
| Elemental Lip Serum | Topical lip treatment | A September 22, 2026 Daily Beast report describes it as a newer addition focused on the appearance of lip lines | Not stated; confirm current details with Elm Biosciences |
What does the A3O serum claim to do?
Elm positions A3O Elemental Serum as an antioxidant treatment for visible concerns linked with environmental exposure and skin aging, including uneven pigmentation, dehydration and irritation. The product is also marketed for sensitive skin. The available launch information establishes the brand’s intended benefits, but it does not provide independent, peer-reviewed clinical-trial results proving those claims.

How does the night cream differ?
The A3O Elemental Night Cream is designed for evening use and adds a retinoid derivative, ectoin and peptides to the A3O complex. Coverage of the January 2026 launch advises people who are new to retinoids to start every other night, increase use as tolerated and apply sunscreen during the day. Retinoids can irritate skin, so people with sensitive skin, those who are pregnant or nursing, or anyone using other active treatments should check with a clinician before adding one.
How much does Martha Stewart’s serum cost?
The published suggested retail price for the A3O™ Elemental Serum was $135 in Elm Biosciences’ 2025 launch information. A complete, current price list for the other products is not established by the cited material, and prices can change.
