It’s June, the sun is finally out, and the heatwave in full flow across the UK - for at least a week. Many of us love the heat and sunshine, while others utter classic lines such as “bit hot isn’t it” before taking shelter indoors and turning the fan onto max.
While we should enjoy the sunshine and take every chance we get to be in it, it is advisable to be careful too. Like with many things in life, sunlight is good in moderation. However, too much sun, or overexposure can damage the skin both on the surface and also at a cellular level.
With this in mind, we are going to take a look at the ways in which sun exposure can affect skin pigmentation. Sunlight consists of a spectrum of different rays: visible light, ultraviolet (UV) and infrared light. Each of these different rays in the light spectrum has a distinct wavelength, and can be measured in nanometers (nm) and millimeters (mm).
How do UV rays affect the skin?
Ultraviolet light is invisible to the human eye. It comes in three different forms: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). UVA rays are less intense than UVB; they are present constantly throughout the daylight hours in a year. However, they fluctuate in strength throughout the day, noon is typically when they are at their strongest.
UVB rays help provide the energy your skin needs in order to produce vitamin D. These rays stimulate the production of melanin and help with tanning. The immediate damage from UVB rays is that it can lead to damage to the skin such as sunburn.
On the other hand, UVA rays penetrate deeper layers of skin and stimulate the production of free radicals in the skin. This can cause oxidative stress and lead to indirect DNA damage. Most commonly, UVA rays are associated with photoaging (premature skin aging), sun allergies and hyper-pigmentation (sun spots).
