The proper use of sun creams

  Miss Vanity can sometimes go out without her umbrella because she knows how to use sunscreen products properly. These are the six rules she uses to keep her skin healthy.

Rule 1: There is no such thing as sunscreen

  One of the big mistakes with sun creams is to trust them too much: no sun product (I mean NONE) can stop 100% of the sun's rays. There is always a part of the UV rays that pass through. The image you should keep of a sunscreen is that of a sieve: the higher the SPF, the smaller the holes in the sieve. This is why it is now forbidden to claim "sunscreen" on a sunscreen product.
  Similarly, a sunscreen does not prevent sunburn: it delays its onset (this is how the SPF is calculated: the ratio between the time it takes for the skin to redden with and without sunscreen). Even with an SPF 50, if you stay in the sun long enough you will still burn!

Rule 2: Choose a sunscreen product that is adapted to your skin and the sun's conditions.

  To choose the right sun care product, it is not enough to test the texture and smell! The most important parameters for choosing your sunscreen are your skin type (the so-called phototype, which is determined by the skin's reaction to sun exposure, to determine yours you can easily find on google) and the sun conditions.
  Indeed, the necessary sun protection is not the same between a stay in Hawaii or in Vancouver! And it's not much use to put an SPF 50 for an evening stroll on the Bloedel Conservatory
  For the phototype, the clearer it is, the higher the chosen SPF must be because these are skins that tan poorly and burn easily. After a certain exposure time, if the skin tans a little, it is possible to change to a lower SPF (for example from 50 to 30).
  For sunny conditions, you should ask about the UV index of your holiday area (or residence). The higher it is, the higher the protection should also be.

Rule 3: You can never use enough sunshine products

  That's a big stumbling block to sunscreen! Because, compared to the amount used to establish the level of protection, and therefore recommended, we simply don't use enough!
  The advantage right now is that we're starting to have finer but equally effective textures, which limits the risk of using very little so that our skin doesn't get sticky/glued. With the dry touch textures that we can have for the face, even in high indices, we shouldn't be afraid to use a lot! Sunscreen is not a foundation, it should not be stretched to the maximum, quite the contrary.
  Same song for the re-application! It's not to sell creams that it's written on them to reapply them every 2 hours, after swimming, doing sports or wiping off. It's simply because UV filters degrade with exposure time (chemical filters anyway) and that roughly after 2 hours the protection offered by your product is significantly reduced. And water, perspiration and rubbing of the towel remove the product from the skin, so you have to put it back on!

Rule 4: a sunscreen product must be removed

  If in the summer we tend to put our foot down on make-up, and thus lighten our make-up removal routine, we must on the contrary pay particular attention to evening cleansing when using sunscreen. Indeed, the textures of sunscreen, as well as the current formulas that are designed to be as resistant as possible on the skin, mean that a simple foaming cleanser is not enough to completely remove the product. In fact, I suspect that a large part of the post-holiday pimples that are always attributed to the thickening of the skin by the sun is due to an inadequate cleansing of the sunscreen!
  To really eliminate all traces of the sun without damaging your skin (which must already be exposed to sun, chlorine, salt, wind, sand, pollution, etc.) the ideal is a double cleansing: a first rather oily make-up remover such as oil/balsam and a second gentle cleanser to eliminate all traces. If two steps really swell you up (because no, it doesn't irritate the skin if you choose your products well), for the summer, choose a make-up remover oil or a balm that emulsifies with water, because you need oil to really eliminate all traces of the sun.

Rule 5: a sunscreen product will stain so be careful with your clothes.

  Since sunscreen products are often designed to resist water and friction, it becomes complicated to remove them not only from the skin, but also from clothes!
  So be careful when handling your sprays on the beach! In fact, one brand is currently advertising its reformulated products so that they do not stain clothing.

Rule 6: change your sunscreen product every year

  When I talk about this rule of changing your sunscreen every year there is always at least one person to reply "yes but that's the brands that say it to sell sunscreen". Well, the problem is that it depends on the sunscreen.
Because a sun product with only mineral filters can actually keep from one year to another because the filters do not degrade.
  But it is the opposite with chemical filters, whose job is to degrade by absorbing UV energy. They are therefore by nature unstable products that have a limited lifespan. All the more so if they are not well-preserved, for example by lugging them in your handbag, at the beach or in the car, because heat strokes accelerate the degradation of chemical filters.
  The problem is that you can't see it with the naked eye, because the rest of the sun care formula hasn't moved. But the level of sun protection is then not at all the same as the one advertised, or even becomes non-existent.
  Since in most cases sunscreen creams contain a mixture of mineral and chemical filters to ensure good UVB and UVA coverage, it is safer to change your sunscreen every season. And it's a bit of a complicated message to say "those with these filters you keep, those with these filters you throw away" so unless you are sure that your sunscreen contains ONLY mineral filters, at the end of the season everyone goes in the trash!
  You too can enjoy the sun without an umbrella if you also go out covered
