ØWhy it’s necessary to protect our skin from the sun?
Moderate sun exposure is beneficial to human health and promotes vitamin D synthesis. However, sunlight is energetic, and prolonged exposure to the sun or lack of attention to sun protection can lead to many skin problems, such as causing sun spots and hyperpigmentation.
When we're exposed to the sun, UV radiation damages the DNA, proteins and other molecules found within our skin cells, says Richard Gallo, professor of medicine at University of California.
More than 80% of melanoma skin cancer cases are caused by sunburn–and this number is rising year on year.
The shorter the wavelength of UV light, the more damage it does to our skin, with the UVA and UVB wavelengths having the greatest impact on skin health.
ØHow to protect skin from UV damage?
Normally what people refer to as sunscreen is UVA and UVB protection.
The PFA value of sunscreen cosmetic labels represents the ability to protect against long-wavelength UVA rays.
The SPF value represents the ability to protect against medium-wavelength UVB rays.
To reach a broad-spectrum sun protection, it is critical to choose the right chemical sunscreen according to the sun protection value required!
