The sun radiation that reaches the skin is constituted by:
*Ultra Violet (UV) =7% *Visible light(HEV)=39% *InfraRed (IR)=54%
Ultraviolet (UV): UVA, UVB & UVC rays. UVA is forming the majority of UV rays that reach the earth with an intensity that presents all year round. These rays induce irritation within the skin and generate free radicals that cause skin damage (pigmentation, wrinkles, skin sensitivity, weakening of its defence mechanism and, in the long term, potentially skin cancer). As UVA is the major contributor to skin ageing, we have increased % UVA filters to give better UVA protection against ageing. The aim is to obtain maximum UVB & UVA protection, more than what the regulations require.
Infrared(IR): IRA, IRB & IRC. Infrared induces significant production of Free radicals in the dermis and diminishes the skin’s antioxidant capacity. IR(A) penetrates deep into the skin (two-thirds reach the dermis) and does not significantly increase the skin temperature. It is a long wavelength of low energy. IRA radiation generates an important quantity of ROS that leads to the destruction of the fibres of collagen type 1 by an enzyme MMP1, also downregulation of collagen type 1. This means that existing collagen is damaged and not sufficiently replaced as the production of new collagen is reduced. Therefore, IRA is an important contributor to the photo-ageing process which accelerates the appearance of wrinkles, age spots and discoloration and makes the skin lose its firmness and elasticity. All light protection spf 50 contains an IR Guard/Blocker to protects the Mitochondrial DNA, it blocks IR- induced free radical formation, inhibits light-induced skin aging-even in deep skin layers, prevents the loss of skin density.
When you look at a chart about the sun’s damaging UVA and UVB rays, you’ll see that their wavelengths range from 280 nm to 400 nm (“nm” stands for nanometer, which is a measurement of length). Next on the spectrum is blue light, defined as light whose wavelength ranges from 380 nm to 500 nm. (The entire light spectrum goes up to 700 nm.)
The blue light portion is what emanates from digital devices, such as computers, tablets, flat screen TVs, fluorescent light bulbs, and smartphones. Both types of UV rays and blue light are bad for your skin and eyes. Long-term blue light exposure to concentrated sources of blue light energy can cause skin damage, including color changes, inflammation, and weakening of the skin’s surface. Simply put, blue light promotes stressors in skin that cause
photo-aging; that is, aging from exposure to light.
Squalane moisturises the skin, has no odor and is non-comedonal, also anti-bacterial properties, anti-ageing. It is 100% natural & sugar derived to reduce wrinkles & enhance spreadability.
Antioxidants, Vitamin E & Ubiquinone (coenzyme Q10) (anti-ageing).
Tripeptides (anti-ageing) that boosts Collagen significantly and it also protects its degradation. It improves skin texture, reduces the appearance of wrinkles & rejuvenates & smoothens the skin.
Alpha Lipoic that has very effective anti-ageing & anti-inflammatory properties.
L-Arginine is anti-ageing by reducing inflammation, aiding tissue formation and is involved in collagen synthesis.
L-Valine (anti-ageing) that stimulates the cells to produce more collagen & elastin.
