Rousselot, a French supplier of hydrolyzed collagen specializing in the health and nutricosmetic industries, recently extended its actives range to cover cosmetic applications. Supported by recent studies, Rousselot is launching Peptan SR marine (Skin Regeneration) and Peptan MR marine (Moisture Retention), topical versions of its Rousselot nutricosmetic active.
“The results of in-vitro studies which we have conducted using specific grades of hydrolyzed collagen have been particularly positive,” explained Caroline Nègre, RHC Marketing Manager.
Fibroblasts proliferation
According to Rousselot, the new Peptan SR marine peptide, which is an active ingredient of marine origin, would boost fibroblasts proliferation and promote the synthesis of collagen.
The new peptide was tested on a culture of fibroblasts. During the first 24 hours, utilized in a dosage of 0.1mg/ml it induced a significant increase of 18% in the proliferation of fibroblasts by comparison with an untreated control, and by 22.5% over 2 days. According to Rousselot, the Peptan SR marine, used at a concentration of 1% in cosmetics formulations, would be capable of restoring the three-dimensional structure of the dermis, giving it cohesion and tonicity, and would also have an antioxidant effect.
Natural biopolymer
The Peptan MR marine is a natural marine biopolymer with film-forming properties. According to Rousselot, it helps maintaining the moisture balance of the skin and provides it with NMF [1]-specific amino acids.
Incorporation into topical formulations
Rousselot’s new range of peptides of collagen is available in powder form, and is preservative free an odourless. Eventually, Rousselot highlights the potential synergies between the nutricosmetic and topical ranges and their complementary capacity to improve the health and beauty of the skin.
