Dermatologists make it clear: there is no such thing as a healthy tan. "A tan is always a consequence of the damage caused by ultraviolet radiation to our skin, and therefore, the best thing we can do to care for our skin is to prevent it," explains Francesc Alamon, a dermatologist at Hospital Clínic. Prevention involves adequate sun protection, physical protection with clothing, hats, and sunglasses, as well as avoiding the hours of greatest sunlight, which "is key to mitigating the effects the sun can have on our skin," adds Alamon. Photoaging and many of the spots and wrinkles that appear on the skin, especially on the face, are a consequence of the photoexposure we have accumulated over the years.

With the arrival of good weather, sun exposure increases, as does the desire to wear new sunglasses. But do we know what we're buying when we choose a pair of glasses? Optometrist Carla Fàbregas gives us four tips.
