Summers are great and we love it because we get to wear all the floral cute dresses. But not everything is great about summers, especially the suntan or sunburns which can make your skin look dull and damaged. When your skin is exposed to sunlight for a long period of time, it starts producing melanin, the pigment which gives your skin it's colour and protects it against the harmful effects of the UV rays of the sun. So the more you stay out in the sun, the more melanin is produced. Over time, this results in skin tan.
