Why does our skin become dark when exposed to SUNLIGHT? answer: .Tanning begins the moment you step out into the sun for most people...As UV rays penetrate the skin,.. it starts to break down DNA in the body. In order for the body to protect itself to prevent further damage to your body,..it starts to produce melanin... The more melanin in your body, the darker the body becomes and the more protected you are from the sun. .👉💡
