Sunlight contains many more parts than what we can see in rainbows. So, if there are so many different parts of sunlight, how do we know which parts help us and which are dangerous to our skin?
I always knew UV light put us at risk of skin cancer, but it wasn’t until I got involved in dermatology research that I learned that most of skin aging is due to UV light too. So how exactly does sun damage our skin?
Sunlight is such a double-edged sword, isn’t it? We love how its energy warms us and gives life to our planet, yet that same energy is incredibly damaging to the very skin that it warms. Our skin works remarkably hard to protect and defend against harmful UV rays, but the bad news is our skin’s defenses alone are not enough.
