About bioCorneum®

bioCorneum is a quick drying, patented silicone gel that creates an invisible, breathable, flexible, and waterproof silicone sheet over scars. It is a clinically proven silicone scar technology that provides protection from the sun with SPF 30 UV protection. The distinctive gel safeguards against chemical, microbial, and physical detriments while improving the cosmetic appearance of scar tissue by binding with the stratum corneum (the outer layer of skin cells). The bioCorneum+® product offering is unique in that it protects the maturing scar from the darkening effects of sun exposure while decreasing transepithelial water loss and increasing the production of fibroblast growth factor to heal skin and prevent abnormal scarring. In a clinical study treatment with bioCorneum following incisions resulted in 67% of scars being rated normal, compared to only 28% without treatment.
