For a hotel built entirely out of salt bricks, itâs surprisingly luxurious. Salar de Uyuni, Uyuni; from $145. Tayka Hotel del Desierto. Nestled into a small hillside in the middle of nowhere, running largely on solar power, this hotel is like a five-star version of a disaster prepperâs shed.
Freckles are not a skin disorder, but people with freckles generally have a lower concentration of photo protective melanin, and are therefore more susceptible to the harmful effects of UV radiation. It is suggested that people whose skin tends to freckle should avoid overexposure to sun and use sunscreen.
So what exactly causes the appearance of freckles? Freckles appear when the melanin, the dark pigment in skin, isn't distributed evenly -- certain areas of the skin have more than others, and that's why they appear a little darker.
