# Elasticity-Promoting Cosmetic Ingredients Azitra Unveils Positive Results for the ATR-COSF Program By Kalin Ned | Published 2026-07-16 | Business Source: Trend Hunter, https://www.trendhunter.com/trends/atrcosf-program References: [marketscreener](https://www.marketscreener.com/news/azitra-announces-breakthrough-repeat-dose-and-anti-wrinkle-ex-vivo-results-for-atr-cosf-program-ce7f5ed2db81f025)  Clinical-stage biopharmaceutical company Azitra has announced promising ex vivo results for its ATR-COSF program — a [cosmetic ingredient](https://www.trendhunter.com/trends/incosmetics-global-2026) formulated from a supernatant derived from an [engineered strain](https://www.trendhunter.com/trends/postbiotic-ingredient) of S. epidermidis that secretes a functional unit of the human filaggrin protein, a key component for skin health. In a multiple-dose study using fresh human skin explants stimulated with TH2 cytokines to reduce native filaggrin levels, the company demonstrated that a 2% lyophilized supernatant in a hydrogel formulation achieved increased penetration and distribution of the recombinant protein through the stratum corneum and into the stratum granulosum with repeated applications. A separate ex vivo study assessed the effect of varying concentrations of the lyophilized supernatant in a hydrogel on human skin elasticity, revealing a dose-dependent enhancement where a 0.28% concentration restored abdominoplasty skin elasticity to levels historically observed in healthy skin, and a 0.3% formulation produced approximately twice the elasticity of a placebo-treated sample.
