The skin of the face is an indicator of our state of health, and, besides, its appearance can influence our self-esteem since the face is the most visible and exposed part of our body. This also makes it the most prone to being attacked by external agents, which is why we have to put special effort into its care. It is essential to use facial sunscreen every day since the facial skin is almost continuously exposed to the sun and UV rays directly. Besides, the thickness of the skin in this area of the body is thinner, making it more fragile and vulnerable to solar radiation.
What is solar radiation?
Solar radiation is the set of radiation emitted by the sun, among which are ultraviolet (UV) and infrared rays.
UV radiation, our skin faces two types of radiation:
UVA: they have a wavelength of between 320 and 400 nm and penetrate the skin’s deepest layers. They trigger the processes of allergies and solar reactions and, in the long term, photoaging.
UVB: its wavelength is between 290 and 320 nm, and they are responsible for the development of redness and burns of the skin, also known as solar erythema.
Infrared radiation: these can enhance the negative effects of UVB and UVA radiation on our skin. Its wavelength is above 760 nm.
What consequences does excess sun exposure have on the skin?
Sunlight, especially UVA and UVB rays, can cause sunburn, premature skin ageing, eye damage, weakened immune system, photoallergic and phototoxic reactions, and even skin cancer. Doctors and dermatologists tirelessly warn about the strong correlation between the frequency of skin cancer and the degree of DNA damage, reminding us that more than 90% of skin cancers result from sun exposure. It is generally known that the best treatment is prevention through sun protection.
