Sunscreen lotions can only reduce skin cancer risks, not fully expel them, scientists warn.
As a new edition of Sun Safety Week begins: find the best sunscreen options for summer 2015. Researchers at the Sun Safety Alliance organize similar events each year hoping to convince people that keeping their skin safe in the sun is vital to prevent skin cancer.
The Sun Safety Alliance has been involved in numerous studies to determine the best protection people can use when exposing their skin to direct sun rays. Their results are constantly enriched with new discoveries related to the nature of sunrays and to the influence they have on the health of our skin.
More than a decade ago, scientists have identified UVA and UVB rays as the main culprits for skin cancer incidence. Nowadays, they are explaining the main differences between the two in order to enable people to better understand the consequences that these have on their epidermis.
In spite of the numerous efforts that are being made to keep oneself protected in the sun, experts believe there is no such thing as safe tan. On the contrary, both UVA and UVB rays are noxious for people as they can cause different types of lesions to the skin.
UVA rays are more common, but also more harmful. 95 percent of the sunrays that arrive on Earth’s surface are UVA. They can cause deeper skin lesions than UVB rays, but the latter should not be ignored, either as they can also lead to skin cancer.
Although people use sunscreen protection, this does not guarantee a 100% efficient protection against UVA and UVB rays. Experts warn people that these measures are only meant to reduce risks; they do not fully expel the negative effects of direct sunlight exposure.
These measures have been once more confirmed during the Sun Safety Week event which will last until the 8th of June. According to the Safety Sun Alliance, ultraviolet radiations reaches its peak between 10 A.M. and 4 P.M.; therefore people should avoid sun exposure during this time interval. Moreover, sunscreens with the highest SPF level should be preferred to the less protective options.
Dermatologists have further advised people to wear hats and to cover their bodies as much as possible if they cannot stay in the shadow during this time of the day. Drinking natural juices and water is also vital during the hot months of the summer as it helps our skin stay hydrated.
Until recently is was believed that the morning sun helps people catch a healthy sun tan, but medical researchers warn people now that the slightest trace of tan suggests the skin is suffering. Suntan, be it as mild as it may be, it is nothing but a sign that the skin has suffered lesions. The gold-brown tan that we all strive for, is just as noxious as the darker tans as they show the skin has been damaged.
Scientists are, nevertheless, aware that people cannot go through the summer months without getting intentionally or unintentionally tanned. Therefore, they recommend people to use as many sunscreen options as possible and to avoid sun exposure during the mid-day interval.
