Exposure to ultraviolet rays does not harm dark-skinned people
This is one of the most common myths about the effects of UV rays on human skin. Most likely, this is due to the ethnic characteristics of many people. For example, owners of fair skin with the first rays of the sun acquire "sun spots"; - freckles, which cannot be said about the owners of dark skin. However, melanin – the pigment that determines our skin color protects the deeper layers of the skin from sun exposure, and works like the skin's natural SPF.
Northern Europeans have it equal to 3.5, while Africans have – 13.5, which indicates the impact of ultraviolet radiation to one degree or another on the skin of everyone person on the planet. In addition, dark-skinned people are more difficult to detect a malignant tumor of the skin. Legendary musician Bob Marley died at the age of 36 from melanoma on his big toe, which went unnoticed for a long time and was unfortunately diagnosed too late.
The higher the SPF number, the better the protection
Theoretically, this information is true. Indeed, the use of protective creams with SPF is one of the most common and affordable methods of protection against the harmful effects of the sun's rays. However, most people don't quite understand the labels on sunscreens. You should be aware of these things:
- cream with SPF 15 filters out approximately 93% of the sun's rays;
- cream with SPF 30 filters out only 4% more UV – 97% rays; The
- SPF number indicates how long the sun protection filters last.
We calculate it like this: the time for which your skin without makeup turns red in the sun, multiply by the SPF number and get the average duration of the product. For example, if your cream has an SPF of 20 and your skin turns red after 10 minutes of sun exposure – the cream will protect her for 200 minutes.
On a cloudy day no UV protection is needed
Many people believe this myth, believing that on a rainy or frosty day protection from UV is not necessary. However, dense clouds – it is only a disguise for the sun, and its rays tend to penetrate even through them. On days when there is no scorching sun, people are outside longer, but at the same time everyone receives a significant dose of ultraviolet radiation, unaware that the sun is harming them.
If you plan to be outside for more than 15 minutes – you must use sunscreen regardless of the weather.
