  • Defends – Prevents and corrects free radical damage

Product performance

Evaluation of Vitamin C delivered to the skin from BioLumin-C Serum versus key competitors Penetration of Vitamin C delivered from BioLumin-C Serum versus two competitor products was measured using Raman Spectroscopy depth profiling. The results show superior delivery of Vitamin C to the skin from BioLumin-C Serum. Calculation of a bioavailability score revealed that BioLumin-C Serum delivered 3x more Vitamin C to the skin than a leading competitor.

Clinical evaluation of BioLumin-C Serum performance- A 30 person clinical study was carried out on BioLumin-C Serum versus a leading competitor by Princeton Consumer Research. Firmness and Luminosity were assessed using instrumental measures and expert clinical grading. In addition, the subjects completed self-assessment questionnaires.

Key product benefits were perceived by the consumer and very favorably received


BioLumin-C is a high performance serum to brighten, firm and help reduce the appearance of final lines and wrinkles, with Vitamin C as the lead technology. The formula was designed to optimize delivery of Vitamin C and superior bioavailability of Vitamin C has been proven (3x a leading competitor). Furthermore, the Vitamin C in the product has been proven to be highly stable (via evaluated temperature testing), meaning that the Vitamin C that is delivered is still in an ‘active’ (unoxidized) form. As well as Vitamin C, the product also contains a short chain peptide and lactic acid to further enhance the key product benefits, as well as natural extracts. The clinical results demonstrated the resultant superior efficacy of the product. At the end of the 8 week clinical study, significant improvements were seen in all key product benefits (firmness, luminosity, skin resilience) and BioLumin-C was also shown to outperform a leading competitor on luminosity (2x greater improvement) and skin resilience (7x greater improvement). Results of a consumer self-perception questionnaire demonstrated that key product benefits are consumer perceivable and that the product was very favorably received.
