The hot, hazy days of summer are just around the corner — and so is overexposure to the sun. Contrary to popular myth, a good tan is not a measure of good health, but actually a sign of skin injury. Too much sun can cause sunburn, wrinkles, freckles, skin texture changes, dilated blood vessels, rash problems and worst of all, deadly skin cancers. Consider using a self-tanner to get that bronzed healthy glow. Here are some suggestions on how to enjoy the sun safely:

Make sure your sunscreen has at least one of these three products: Titanium Dioxide, Zinc Oxide or Avobenzene.

Try and use a lotion that has a SPF protection of at least 30, although most dermatologists recommend SPF 15, on all exposed skin, including the lips, even on cloudy days.

If exposed to water, either through swimming or sweating, a water-resistant sunscreen should be used.

Reapply sunscreen frequently.

Sit in the shade whenever possible.

Wear protective, tightly-woven clothing.

Plan outdoor activities early or late in the day to avoid peak sunlight hours between 10 a.m. and 4 p.m.

Ultraviolet light ages your skin. And the reason it does that, it's a longer wavelength, so it can penetrate deeper into the skin and it attacks the layers that give your skin its tone and its elasticity, and as a result you get the lines, the wrinkles, all the things associated from aging,.

In all parts of the world, except for the US, you can enjoy products made with a wonderful chemical called Mexoryl -- known to give you an almost perfect protection against sunshine.

However, for whatever reason, you cannot legally buy it in the United States because the Food and Drug Administration won’t approve it. They won't even say why. Mexoryl has been in use in other countries for 13 years and has passed many safety tests. Although buying or selling sunscreens with Mexoryl is illegal in the United States, that doesn't mean sunscreens with Mexoryl aren't bought and sold here. I have seen it at some pharmacies. It was expensive though, between $30 to $50.

My list of the top five sunscreens:

La Roche-Posay, XL Lait SPF 60. However, this has Mexoryl, and isn’t approved for sale in the US.

Bull Frog Superblock SPF 45

Neutrogena Ultra Sheer Dry-Touch Sunblock SPF 55

Clinique UV-Response Face SPF 50

Elta Gold UV Shield SPF 45.
