My skin under the sun: 8 burning questions

What are the harmful effects of UV rays on the skin?

“In the first place, skin aging: sun exposure is responsible for 80% of the signs of aging, what are wrinkles, spots and loss of elasticity”, warns Dr. Marie-Estelle Roux. UV rays also cause sunburn when the exposure time has been too long or the sun protection insufficient. “Repeatedly, they can make the bed of skin cancers, the most dangerous of which is melanoma”warns Dr. Roux.

Is it true that everyone has solar capital? How do we know where we are?

Yes, it’s true. The sun capital designates the ability of each person to resist UV rays. It depends on its phototype, a “categorization” of skin types that takes into account the color of the epidermis, eyes and hair. There are 6 different ones: the higher the phototype, the greater the solar capital. Only, by dint of exhibitions, it deteriorates. “We know that our sun capital is depleted when we get sunburn much more easily than before, that white spots appear on the legs and brown marks, similar to freckles, develop on the shoulders, says Dr. Roux. It is exhausted when you have keratoses, a crusted lesion, or skin cancer.

Do solar capsules work?

Yes, thanks to powerful antioxidants (vitamin E, zinc, copper, lutein, etc.), as well as active ingredients such as beta-carotene, lycopene and lutein, they can be useful in preventing sun allergy and promoting tanning. Studies prove that they increase UV tolerance by 20%. “On the other hand, they do not replace sun protection”, says the dermatologist. Ideally, they should be taken one month before your departure.

Which cream should I choose?

Those containing mineral filters instantly protect against UV and blue light. However, they have the disadvantage of leaving a white film on the surface of the skin. Those based on chemical filters require 20 min of patience but do not leave a whitish deposit. The trick? Choose a sunscreen that combines these two systems or opt for a tinted mineral cream. “Regarding the solar index, I recommend giving priority an SPF 50 on the face and décolleté in case of fair skin, an SPF 30 in case of matte skin, as well as an index 30 on the rest of the body”, advises Dr. Roux. As for the texture, it doesn’t matter: oil, milk, cream…choose the one you like the most so that you enjoy getting over it regularly.

How much to put in to be effective?

It is recommended to apply the equivalent of 6 teaspoons on the body and 1/2 on the face.

Be careful, once wet, the protection is zero: in this case, opt for anti-UV t-shirts. Also wear a hat with wide brims of about 7 cm to protect your face and neck well, not to mention wrap-around sunglasses in categories 3-4 for your eyes.

Does a tan protect the skin?

It slightly protects the skin against sunburn but it has no effect against photo-aging and the formation of spots. It is therefore better to keep an SPF 50 if you have fair skin. and never go below an index of 30 if you have dull skin.

It’s gray. Should I still protect myself?

Cloudy weather does not allow you to be less vigilant in relation to the sun, clouds letting 90% of UV rays through! On the other hand, if the sky is really cloudy or it’s raining, you can do without sun protection.
