Exposure to the sun without the issue of photoprotection is the most important aggressor of the skin and causes cumulative damage. "It also causes changes in the basics of cellular DNA that cause cellular mutation reactions, leading to premature photoaging, inflammation, and cancer," says Dr. Claudia Marçal, a dermatologist at the Brazilian Society of Dermatology and the American Academy of Dermatology. And the best form of protection is sunscreen. But there are areas of the body that are often neglected and can suffer from sunburn or, because of cumulative damage, more serious changes.
HOW TO GUARANTEE EFFECTIVE PROTECTION
The sun exposure has these predefined and recommended periods: at 10 am and after 4 pm because the incidence of ultraviolet B radiation is lower during of these periods. "From 10 to 16 hours, there is combination of ultraviolet B and ultraviolet A radiation, with longer and longer rays,"
In addition to these times, sunscreen, explains the doctor, should be applied at least 30 minutes before direct sun exposure, in addition to a no SPF. SPF 50 minimum should be used for lighter and lighter skin. "This sunscreen has to combine chemical and physical filters." Physical filters are inorganic particles that reflect or disperse radiation, while chemicals are organic particles that absorb energy photon. Titanium dioxide, iron oxide and zinc oxide are fundamental, they act like a brick wall – where the light hits and comes back without absorption.The chemical filters are important but extremely unstable, then sweaty in seawater, the molecule becomes chemically unstable and no longer protects, "he said. "The filter must offer effective protection against UVA and UVB rays, but also against visible light and infrared – there is today a worldwide unanimity regarding the need for a wide range of solar filters. "
Finally, in addition to the use of hats, caps and clothing SPF 50, the new application of the protector every 2 hours or after 20 minutes in the water and in the correct amount. Choose protectors with a formulation that, besides the SPF, have soothing extracts such as Edelweiss, physalis with antioxidant action, Alistin, OTZ 10, Exo-P and vitamins with free radical action and protecting the damage caused by the infrared, such as vitamin E, vitamin C, nicotinamide, among others. "Orally, supernovity is the daily use of vitamin D that contributes to the immune protection of the skin, as well as pycnogenol, polypodium leucotomus, zeaxanthin, lutein, bio-arct and lycopene."
Discover the peculiarities of seven areas of the body forgotten in photoprotection:
PIPES AND INTERNAL CORN EYES
The eyelids and the eye area have become a worldwide concern in the face of increasing the number of skin cancers, which already reaches 10% in these often neglected areas, according to research from the University of Liverpool presented at the annual conference of the British Association of Dermatologists last year in the United Kingdom. The study found that by pbading sunscreen on the face, one tends to forget about 10% of the face, including the eyelids and the area between the inner corner of the eye and the eye. the nose. "Adequate sunscreen should be provided effectively with full face coverage, in addition to the use of hats and especially sunglbades, as the eye area has extremely thin skin and is susceptible to damage, especially cancer, "says dermatologist Dr. Claudia Marçal. The dermatologist explains that the application of sunscreen in these areas is not necessarily practical, it is important to use other forms of protection, such as eyeglbades. Sun. "The skin of the eye area is very delicate, some filters can cause irritation, so the patient should give priority to products tested ophthalmologically, protecting the area without risk of reaction," he said . "But we must remember the importance of sun protection accessories, such as sunglbades with UV protection, which not only protect the eyes and the cornea, but also the skin of eyelids prone to cancer", explains there. 19659005] CANTOS AND NOSE POINT
According to the University of Liverpool study, other forgotten regions are: the corners and the tip of the nose. "As this is one of the strengths of the face, the nose is one of the first to turn red, suffer burns and, in the future, stains and even cancer. not to be forgotten and the patient must spread the filter well over the entire length of the nose. "
MOUTH AND LIP REGION
In the area around the lips and mustache, the photoprotector must be well applied to avoid stains and avoid or soften the famous "barcode" (vertical wrinkles that lodge in the contour of the upper lip). In the case of lips, you can use a lip balm or lip balm with SPF, says Dr. Claudia.
EARS
Perhaps the most forgotten sunscreen, ears can, over time, present wounds due to wounds. the sun "So be careful when applying (and reapplying!) the protector at every turn and corner and also invest in a wide-brimmed hat to protect them too."
NUCA
Do not think that your long hair will protect you from sunburn on the back of your neck. The ideal is to use the photoprotective in this area often exposed directly in the pools.
FEET FEET
You are already almost completely covered with the photoprotector, but your feet can be burned if they are neglected. Often on the beach, the body remains in the shade, but the foot directly receives radiation. This is perhaps one of the regions that suffer the most from the photo-acquired aging process (and also one of the most reported).
