TOSLA x GELTOR: When Biotechnology Meets Formulation Expertise

TOSLA and Geltor Redefine the Future of Vegan Collagen!

The future of ingestible beauty will not be defined by ingredients alone, but by how advanced science is translated into products people actually use, consistently, over time. 

That belief serves as the cornerstone of the TOSLA × Geltor collaboration, marking the launch of the Signaling Collagen Shot —the first ready‑to‑market liquid supplement powered by biodesigned, vegan Type 21 signaling collagen. 

This partnership brings together two complementary strengths: breakthrough protein biotechnology and real‑world formulation excellence, that is moving signaling collagen from scientific possibility to consumer reality. 

A New Model for Innovation in Ingestible Beauty 

Biotechnology is opening new frontiers in collagen science. But innovation only creates impact when it crosses the gap between lab‑grade discovery and daily consumer routines. 

Geltor’s PrimaColl® Type 21 signaling collagen represents a new generation of collagen innovation. Produced through precision fermentation, it is a biomimetic, vegan collagen polypeptide designed to support key skin‑signaling pathways—a rare collagen type that cannot be sourced from animals and can only be created via biotech. 

TOSLA’s role in this collaboration has been to translate that scientific breakthrough into a fully developed, scalable, and enjoyable liquid supplement, designed for consumers’ consistency, compliance, and long‑term use. 

The result is a sensory rich finished product, ready for brands to bring to market. 

From Signaling Science to Daily Ritual 

PrimaColl® has been evaluated in a randomized, double‑blind, placebo‑controlled clinical study involving 170 women over 12 weeks, with 80–92% of participants showing improvements in skin firmness, elasticity, moisturization, and wrinkle depth at daily intakes of 1–2.5 g. 

But clinical efficacy alone does not determine market success. 

One of the biggest barriers in supplementation remains long‑term adherence. That challenge sits squarely at the intersection of taste, convenience, and habit formation, where TOSLA has built its formulation philosophy. 

By pairing PrimaColl® with TOSLA’s proprietary VELIOUS® Flavor Technology, the Signaling Collagen Shot delivers advanced biotechnology in a smooth, Cherry-Raspberry flavor, ready‑to‑drink liquid format, designed to fit seamlessly into daily routines. 

Why Collaboration Was Essential 

This collaboration is designed to inspire ingredient innovators and wellness brands alike to rethink what’s possible when efficacy, experience, and scalability are developed together, and to bring the next generation of ingestible skincare to market. 

“Biodesigned ingredients like PrimaColl represent an evolution in collagen science, but innovation means nothing if it doesn’t reach consumers,” said Alex Lorestani, CEO and co-founder of Geltor. ”Our partnership with TOSLA bridges that gap, transforming breakthrough biotechnology into a ready-to-market solution that brands can confidently launch. This collaboration proves that when you unite ingredient innovation with formulation expertise, you create something consumers actually want to use every day.” 

Uroš Gotar, Chief Innovations Officer at TOSLA added: “TOSLA was built on the belief that efficacy alone is not enough—ritual drives results. Our partnership with Geltor brings together breakthrough biotechnology and sensorial design in a way that feels seamless in daily life. With PrimaColl, we are transforming advanced science into an experience consumers can look forward to, because when wellness becomes a ritual, adherence follows, and results are realized over time.” 

Liquid as the Enabler of Signaling Collagen 

The choice of a liquid delivery system was not incidental. 

Liquids allow clinically relevant doses to be delivered in a single, easy‑to‑use serving—while supporting better absorption, convenience, and sensory appeal. More importantly, liquid formats foster habit formation, which is essential for signaling‑based ingredients that rely on consistent daily use over time. 

This format transforms advanced biotechnology into a daily beauty or wellness ritual, where adherence becomes intuitive rather than forced. 

Creating New Opportunities for Brands 

The Signaling Collagen Shot was developed with brand partners in mind—particularly those looking to lead, rather than follow, category trends. 

This collaboration supports two key strategic expansion paths: 

Backed by TOSLA’s formulation and manufacturing expertise, the product is fully ready‑to‑market, enabling brands to activate quickly within a rapidly evolving collagen landscape.
