Summer rhymes with sun, tanning … and sometimes big sunburn. However, even with a sunscreen in the bag, there are many of us using it. Doctor Anthony Rossi, dermatologist and surgeon at the Memorial Sloan Kettering Cancer Center, shares his recommendations in the magazine Buzzfeed To better protect yourself. He lists the gestures to be corrected urgently if we want to avoid long -term skin damage.
These current errors with sunscreen according to a dermatologist
Contrary to popular belief, a high SPF does not mean that you can bask in the sun longer. SPF, or sun protection factor, does not indicate a duration but a level of protection against UVB. “”From a SPF 30, it is considered that sun protection is sufficient, because it is at this stage of the SPF curve that the level of protection stabilizes“, Specifies Dr. Rossi. A SPF 50 therefore does not block twice as many shelves as a SPF 30.
Another frequent fault is to choose a sunscreen that does not protect wide spectrum. It is essential to block both UVBs, responsible for burns, and UVAs, which accelerate skin aging. “”They are both harmful to the skin“Recalls the specialist.
Cosmetics with SPF do not have the same efficiency. The doctor insists: a foundation with UV index never replaces a real sunscreen. “”The makeup SPF must just be considered a bonus“, He explains. The ideal remains to apply its sun protection, wait until it dries, then make up.
Another frequent error: badly use solar sprays. Even if they are practical, their application is often incomplete. To be effective, you must spray directly on the skin and spread the material well. “”Rather, it is the creams, lotions or emulsions that facilitate homogeneous coverage“, Specifies the doctor.
Apply too little, too late, or not every day
The quantity plays a decisive role. Many underestimate the necessary dose. To cover the body well, Dr. Rossi recommends applying the equivalent of a small glass to liquor. For the face and neck, count the equivalent of two to three product fingers.
Another ignored point: the weather. You shouldn’t wait for the sun to get strong to protect itself. The UVA cross the clouds, and your skin is exposed even when the sky is gray. The good reflex is to put it on the exposed areas every day, such as the face.
And that’s not all. Even inside, sunscreen can be useful. If you work near a window, UVA rays can still reach your skin. “”Simply because UVA rays also penetrate the windows“Explains Doctor Rossi.
Finally, not putting back cream once tanned is a false idea. Tanning is not a shield. “”Melanin does not protect you from UVB rays“, Concludes Dr. Rossi. The skin can always burn, even well golden. Apply sunscreen all summer remains essential to preserve the health of the skin, and prolong the outfit of the tan.
