Infrared radiation, in particular near infrared (IR-A), has the ability to penetrate deep into the dermis. Recent studies have shown they generate free radicals and produce other harmful biological effects to the skin resulting in aging and wrinkles. Kobo (stand F100) has screened numerous particulate materials and selected two specific grades of titanium dioxide which showed a great capacity to block IR-A. These materials are offered with a variety of surface treatments.
