At in-cosmetics Latin America, Lonza will feature its new Bioactive Functional ingredient, ScreenLight Block, which helps protect skin against the visible effects of blue light, UV light and pollution.
“ScreenLight Block provides a powerful defensive shield against the visible skin ageing effects of blue light and more,” said Vanessa Arruda, PhD, global market development manager, Bioactives. “Consumers who use their cell phones and computers extensively can apply facial creams that not only mitigate the visible effects of the blue light emanating from their screens, but also help protect their skin against the effects of UV stress and pollution.”
Arruda noted that environmental stressors can degrade unprotected skin and reduce the availability of MFAP4, fibrillin and elastin, leading to loss of elasticity, skin photoageing, worsening wrinkles, fine lines and hyperpigmentation.
Third-party in vitro testing showed that ScreenLight Block acts differently under different stress conditions. Under visible light and under conditions of artificial pollution, the bioactive decreases melanin synthesis in the skin. Under UV stress ScreenLight Block protects collagen and increases skin elasticity. Clinical trial results showed that ScreenLight Block helps reduce the appearance of dark spots, resulting in skin that appears more evenly toned, and helps reduce the appearance of fine lines and wrinkles.
Lonza produces the ScreenLight Block by using Supercritical CO2 extraction, a more environmentally friendly process than traditional extraction techniques. The Physalis alkekengi extract, from a subtropical fruit better known as Chinese Lantern (pictured) and rich in phytosterols, is obtained by the Supercritical CO2 process. Beta carotene is obtained by the fermenting fungus Blakeslea trispora.
