Biray special finish Skin+® is a patented microencapsulation technology that provides skin-related benefits (rejuvenation & anti-ageing, increased moisture level, softer & smoother skin) by means of carotenoid-producing probiotics. The carotenoids (anti-oxidants) are 10 times more active and stable than those produced by carrots or tomatoes.

Inactive probiotics are encapsulated and integrated in the fabric. Friction between the body and the fabric opens the microcapsules and releases the spores. The spores absorb humidity and self-activate: they are transformed into probiotic bacteria and start to produce carotenoids (anti-oxidants). The carotenoids reach the skin even through textile substrates.
