SAN DIEGO, CA / ACCESS Newswire / October 15, 2026 / Dermata Therapeutics, Inc. (NASDAQ:DRMA) (“Dermata,” or the “Company”), a science-driven leader in dermatologic solutions, today announced positive topline results from its recently completed cosmetic clinical study evaluating Tome Foundational Treatment, the Company’s recently launched once-weekly skin renewal treatment. Tome Foundational Treatment is now available for purchase at www.tomeskincare.com either as a one-time purchase of four weekly treatments or through a subscription program at a discounted price.

Dermata’s recently completed cosmetic clinical study consisted of 31 participants in an open label study of Tome Foundational Treatment. Participants applied Tome Foundational Treatment one time per week for four weeks and were evaluated by an investigator at multiple timepoints throughout the study on endpoints including fine lines, hyperpigmentation, dark spots, smoothness, firmness, radiance, and overall appearance. Participants also completed self-evaluations after four treatments.

The topline clinical study findings include:

Additionally, 93% of participants agreed that Tome Foundational Treatment was comparable to a professional in-office procedure and 90% agreed they saw more noticeable results compared with other products. The study also found that Tome Foundational Treatment was well tolerated by participants, with no treatment related adverse events reported.

“We are extremely encouraged by these topline results, which provide clinical support for what we set out to accomplish with Tome, to create a fundamentally different approach to skincare,” commented Gerry Proehl, Dermata’s Chairman, President, and Chief Executive Officer. “Dermata was founded on clinical rigor, and we believe these data help provide the backing for our claim that Tome is ‘studied skincare’. We believe these topline results demonstrate the potential that a once-weekly skin treatment can visibly renew the appearance of the skin and provide compelling clinical validation at an important time as we introduce Tome to consumers,” continued Mr. Proehl. “We are encouraged by the reception we have seen from the recent launch of Tome Foundational Treatment and look forward to expanding its recognition in the skincare space. We continue to build awareness around the Tome brand, and believe these clinically demonstrated results, combined with the simplicity of a once-weekly routine, can provide meaningful differentiation for Tome Foundational Treatment in the premium skincare market,” concluded Mr. Proehl.
