Daylight protection

The solar spectrum is composed of various wavelengths which penetrate the skin to various depths. The longer the wavelength, the deeper the rays penetrate the skin. Even in the shade, radiation from the sun can still penetrate your skin & part of the suns rays can reach through water and glass, such as windows in the home and car.

Visible light & infrared-A

Visible light and infrared-A have also been shown to cause damage to the skin and lead to premature skin aging. Among the visible light spectrum is Blue Light which is also emitted by the screens we use every day. Long-term blue light exposure can cause skin damage, including colour changes, discomfort and weakening of the skin's surface.

Atmospheric pollution

Studies show that air pollution has a significant effect on our skin. Pollutants like cigarette smoke, dust, smog and vehicle exhaust can have a negative impact on our skin, such as decreased elasticity, discomfort and accelerated aging.

Free radicals

Free radicals are unstable molecules that can cause damage to our cells. Due to their reactive nature, free radicals can wreak havoc on your skin and other cells causing oxidative stress which can damage DNA and cell structure.
