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).
