If you want to have healthy, smooth, even-toned skin and good health later in life you may want to update your knowledge on the exposure of your skin in the sun and common myths, which can jeopardise long-term skin health!
Myth – all sunscreens protect against UVA (ageing) and UVB
"Many people think that
applying any older SPF will help keep us safe from both kinds of the sun’s
harmful rays,” says Sharon Maxwell, International Dermal Institute.
"Unfortunately, this is not true.”
SPF (Sun Protection
Factor) theoretically indicates how long it will take for UVB rays – the main cause
of sunburn – to burn the skin. For
example, SPF 15 allows a person to stay in the sun 15 times longer without
burning than they could without sunscreen. This has nothing to do with UVA
rays, which are the same rays emitted by sun beds. UVA rays penetrate the skin
more deeply and play a major part in accelerating the signs of skin ageing and
generating skin cancer.To protect your skin from
both UVA and UVB rays, don’t just buy a product with an SPF of 15 or higher.
Make sure it is labelled "Broad Spectrum,” which means it contains a
combination of ingredients known to protect skin against both types of UV rays.
The American Academy of
Dermatology recommends a "liberal use” of SPF 30 for the body, and reapplying every two hours or after swimming or exercising.
For the face, the rule of thumb is one teaspoon of sunscreen to deliver the SPF
on the package.
Myth – A base tan will
protect me from the sun.
There is no such thing as
a safe tan. By definition, a suntan is
your skin’s defence to bring harmed by UV exposure. Your cells respond to the affront by producing
more melanin (pigment), and your skin darkens as a result. There is nothing healthy or preventive to be
gained from trying to acquire a base tan.
The same goes for the "but
I need Vitamin D” argument. Experts
agree that after 15 minutes in the sun, your skin stops producing the vitamin;
if it didn't, toxic levels would make you sick. Vitamin D can also be acquired
through food and supplements, which negate the need to spend too much time in
Myth – it’s cloudy outside!
I don’t need sunscreen.
Sun damage doesn't just
happen during the summer months or at the beach. Photo damage or UV exposure (which causes
ageing) can offer from exposure to daylight through glass and eve fluorescent
indoor lighting. This is why protecting of photo ageing is preventable by
wearing a Broad Spectrum sunscreen daily, so lather up!
