Which SPF to choose, how to have a nice tan, how to relieve sunburn and avoid peeling…? So many questions that arise for us at the beginning of the summer period full of sun. So, to enlighten you, we've selected the ten most frequently asked questions about sun exposure. We also interviewed Dr Emmanuelle Besson Targe, dermatologist, to provide you with clear and precise answers on this subject.
How to choose your sun protection and when to apply it?
The term SPF is an English acronym, translated as FPS "Solar Protection Factor" in French. It measures the level of protection of a sun product against only UVB rays, the UV rays responsible for sunburn. Protection against UVA rays, which are much more harmful to the epidermis because they reach the dermis and alter collagen and elastin, is mentioned on the bottle by the circled UVA term to which is appended a number indicating the sun protection capacity.
There are four levels of SPF. The SPF 50+ index expresses very high protection. The SPF index 50 to 30 indicates a level of high protection. The SPF 25 to 15 index is the one that offers medium protection and the SPF 6 to 10 index indicates a very low level of protection. Sunscreens include sun filters which can be chemical and / or mineral.
The dermatologist, Dr Besson Targe, is categorical about the choice of SPF: "The basis, the essential gesture, is sun protection with a total sunscreen index of at least 30. It is advisable to favor the index 50 and / or physical protection - cape, hat, tunic instead of tank tops. " The Dr also specifies that "In general, you should apply it regularly, at least every 2 hours, throughout the day when you are exposed and not just once in the morning after your day cream. When bathing, reapply as soon as you get out of the water. Also think about your sunscreen for your lunches on the terrace! The journeys on foot or by bicycle are also times of strong exposure to the sun. "
What about the organic sunscreen, octocrylene?
Octocrylene is a sunscreen that absorbs short-wave UVB and UVA rays which are responsible for aging and skin cancer. A study, published on March 8, 2021 and carried out by a Franco-American team of researchers from CNRS and Sorbonne University, has shown that this filter degrades, within the bottles, and turns into benzophenone, a compound suspected of carcinogenic and endocrine disrupting.
The International Agency for Research on Cancer (IARC / Iarc) of the WHO has classified benzophenone as "Possibly carcinogenic to humans (Group 2B)". While waiting for better regulation from the authorities, we advise you to avoid sunscreens listed in the list INCI includes octocrylene.
Should I use city sunscreen different from beach sunscreen ?
Clearly yes! The nature and duration of exposure to the sun do differ depending on whether you are in the city or at the beach. In town, we recommend that you apply a SPF 50+ sunscreen based on organic filters over your skin cream to avoid white marks, but check the presence of the two anti UVA and anti UVB protection statements. . If you are using foundations; know that today there are even waterproof ones with SPF 50% + sun filters with good UVA and UVB protection.
On the other hand, for your sports activities and your sea baths where you expose yourself for a longer period of time to the sun, it is preferable to favor sunscreens based on mineral filters, without nanoparticles of course, to preserve our corals and our oceans. And the best advice for you will always be to protect yourself by wearing a hat all the time, it looks so pretty too!
In any case, whether it is city or beach sunscreen, more than ever it is essential to use a good cleanser when you get back home in order to remove all the residue of these sunscreens that , given their texture, will tend to clog the pores. Lotion Pure Merveille is perfect for this type of cleansing and will soothe your sun-inflamed skin. For stubborn traces, consider removing them with cleansing oil Philtre Sacré.
Can you tan with sunscreen?
The answer is yes ! Despite popular belief, even the highest sun protection, 50+, won't stop you from tanning. As the name suggests, it only provides 50% UVB protection. This is why, regardless of your dark or fair skin tone, we recommend a sunscreen with a maximum SPF 50+ index. Applying sunscreen is truly a beauty gesture to incorporate into your summer ritual before any exposure.
How to avoid peeling in the summer?
If you have failed to follow the advice above and caught a sunburn, you risk peeling during the phase of desquamation and scarring of your skin ... Goodbye to the tan so hard obtained! To limit the damage, Dr. Besson-Targe relies on hydration: "[...] essential gesture to have beautiful skin all year round! In the summer, this will prevent peeling and help keep a beautiful tanned complexion for longer. ". Hydration is not limited to applying your moisturizer, consider drinking at least 1.5 liters of water per day. In addition, a few days before your exposure, you can prepare your skin by performing a gentle exfoliation with Pépite de la Palmeraie which will help eliminate dead skin and benefit more from the hydration of your cosmetic treatments. Be careful, however, not to overuse scrubs during the summer with a twice-weekly use, as this could refine and weaken your skin, which would thus be more sensitive to attacks from the sun ...
How to relieve sunburn?
There is not just one type of sunburn and solutions differ depending on the severity of the UV burn.
In the light burn, your skin is red, painful and when you press with a finger on the affected area it turns white ..., the application of a good gel of Aloe Vera in addition to your moisturizer will be of great help in soothing redness after a few days.
The more significant burns are distinguished by the appearance of blisters on the skin and require the use of a soothing and healing cream to be obtained in pharmacies. Healing will take longer and the application of oily and disinfecting ointment will be appropriate.
How to prevent a sun allergy?
Sun allergy, called actinitis or lucitis, is a mild disease that usually shows up as small bumps and red patches locally on exposed areas. It can be accompanied by itching which should not be given up at the risk of causing severe pain.
According to the dermatologist, “The treatment for lucites depends on their severity. The basic treatment is based on protection with a very broad spectrum anti UVB and UVA sunscreen accompanied by wearing a hat. If you are prone to lucites, help your skin with food supplements based on carotenoids to be taken before sun exposure. Depending on the deterioration in the quality of life and the symptoms, specific treatments should be discussed with the reference dermatologist. "
How to protect acne-prone skin from the sun?
Acne-prone skin tends to produce excess sebum. They are therefore afraid of sunscreens whose presence of filters, minerals or chemicals, makes them occlusive. Dr Besson-Targe recalls that there is “Sun creams specific to acne-prone skin. Look for a product with a non-comedogenic and non-acnegenic claim. For this type of skin, double cleansing is recommended after sun exposure with a cleansing oil and then a lotion. "
Dr Besson-Targe adds that "The exposure should also be gradual to also avoid acne rebounds due to stopping the anti-inflammatory 'treatment' that is the sun."
What types of cosmetics should I avoid in the summer?
When exposed to the sun, it is important to adapt your beauty ritual to the risk of weakening your skin in the more or less long term. Exposed to UVB, the skin protects itself by producing melanin which will thicken the stratum corneum and therefore better protection against solar radiation. Your n ° 1 enemy are therefore fruit acids and retinol, derived from vitamin A. Indeed, the latter, which aim to exfoliate the skin, weaken and refine the protective barrier of your epidermis, thus making the skin more vulnerable to UV rays. Care based on fruit acids or retinol should therefore be avoided during your summer vacation. You may even cause a strong inflammatory reaction or permanent spots on your skin.
Why don't our treatments contain sunscreen?
You have surely noticed that in recent times, UV protection in day creams has become popular. So why don't our treatments contain it? For us, it is essential to opt for the maximum protection 50+ when we are exposed to the sun. It is therefore preferable to have a sunscreen product specific to this need to apply occasionally. Indeed, the formulation of a sunscreen product is neither suitable for long-term daily use - occlusive nature of the filters - and not even sufficiently dosed in active ingredients targeting the daily needs of the skin (hydration, firmness, regeneration, repair, etc.). On the other hand, our cream " Ange Sensationnel »Offers a good basis for an association with a sunscreen product. Our cream should be applied first.
But if you go to the beach, we clearly have a preference for the hat and mineral filter sunscreens without nanoparticles, especially since there are some now with smoother and less pasty textures. You will thus participate as much as possible in the preservation of our seas and our oceans!
