The active cream may display an SPF 25, with the help of 2% of the Haematococcus active. These results confirm the in vitro results. Both test results confirm the efficacy of the Haematococcus active to act as an SPF booster.
Waterless sunscreen formulations with unique sensoriality Empowered with this natural, sustainable, and biocompatible active emollient, Natura- Tec developed two waterless sunscreen formulations with a unique sensoriality: ‘Sun Protect & Repair Solid Cream in Stick’ and ‘Invisible Upcycled Sun Oil’. These formulations are based on natural and sustainable ingredients and deliver a unique sensation of lightness and smoothness leaving a delicate veil on the skin insuring sun protection, nutrition, and wellness. First, ‘Invisible Upcycled Sun Oil’ is an
ultralight sun protective oil that will instantly penetrate the skin leaving it smooth, stimulated and hydrated without any oily residue nor tacky feeling while protecting it from UV and blue light damages thanks to the biomimetic microalgae Haematococcus active, boosting endogenous antioxidant production and SPF.

Secondly, ‘Sun Protect & Repair Solid
Cream in Stick’ is a multifunctional and solid formulation providing sun protection and hydration, while boosting the skin barrier function, in need of comfort when summer comes to an end, thanks to the microalgae active, Natura-Tec Marine OceanMist CL™.
Conclusion Cumulative oxidative stress, the formation of free radicals and their adverse effects on the biological systems of skin cells are the common mechanisms of skin ageing processes. Naturally, the skin protects itself by producing significant amounts of antioxidants. However, in the event of prolonged exposure to UV lights, the increasing production of reactive oxygen species induces oxidative stress responsible for skin ageing. In this case, the green microalgae
Haematococcus pluvialis, the most important source of asthaxanthin, a very powerful carotenoid, associated with cranberry seed oil, a super fruit rich in antioxidants and sterols, will work in symbiosis with combined effects for a targeted action of protection of the skin against environmental stress, including high

energy radiation sources. Due to its unique composition, Natura-Tec
SeaBerry Blue™ increases the concentration of skin antioxidants, when subjected to stress by UVA, UVB or blue light exposure through biomimetic pathway, boosting skin natural protection against environmental aggressions. It also strengths the natural ability of the skin to fight against external factors such as ultraviolet radiation by providing it photoprotective and photostability properties, acting as an SPF booster.
