Timeline
The story of Collagena Professional begins with the research of Eng. Tanya Roganska.
Patent No. 60945 for a collagen hydrolysate of exceptional purity: a breakthrough that made the brand a benchmark of Bulgarian cosmetic science.
Lines for salon treatments and for home care. ONE Cosmetix is the official distributor for Bulgaria.
Science and principles
The collagen hydrolysate under patent No. 60945 is 99.5 % pure, per the manufacturer, with a molecular weight between 2,000 and 2,500 daltons. At that size collagen is no longer a whole protein but peptides that can become part of a care formula.
What of it reaches the skinEvery product is made to work with the skin's own processes. The formulas rely on biocompatible ingredients, and none of the declared recipes contains parabens. We publish the INCI list of every product the manufacturer has provided one for, so you can check each formula yourself.
To the productsThe formulas were clinically tested for safety and efficacy at Ivan Pavlov Medical University in Sofia and at Romenhas Paris.
