10 mistakes you shouldn’t make with sunscreen
No, you can’t reuse your sunscreen from last year. You can’t make your own sunscreen either. Zoom in on the “false good ideas” to avoid!
Reuse last year’s sunscreen. Caution: sun creams (also) have an expiry date: in general, they keep for a maximum of 12 months after opening. You should also avoid reusing last year’s sunscreen, especially if it has been in the sun for hours and/or locked up warm in the car. Phased sunscreen (i.e.: with an oily deposit on top and possibly a bad smell) is good for the trash can!
Choose your sun protection at random. Rule n°1 to choose your sun cream: respect your phototype! For example, very pale skin that does not tan will opt for a sun cream with an SPF 50+ that blocks a maximum of UVA and UVB rays. Fair skin that tans a little will choose a sun cream with SPF 50. Fair and matt skins that tan easily will opt for an SPF between 15 and 30. Finally, black skins can choose an SPF 6 to 10 – don’t hesitate to ask your pharmacist for advice.
Spread it once, and then that’s it. It is necessary to spread sunscreen (at least) once every two hours and after each swim. even if the product is stamped “waterproof”! The palest skins will renew the application even more frequently to protect themselves as best as possible against UV rays.
Buy a different sunscreen for children and adults. According to a survey by the magazine 60 million consumers published in June 2017, there is no need to buy different sunscreen creams for children and adults since the compositions are almost identical. In short, a good sunscreen (to be bought in pharmacies, with a sufficient protection factor) is more than enough for the whole family…
Just make do with the sunscreen. Wearing sunscreen to protect your skin from harmful UV rays is a must, yes, but not enough! It is also essential to avoid exposure at the sunniest hours (between noon and 4 pm), wear a hat and sunglasses, and complete the picture with a T-shirt for children. In addition, (with very pale skin that burns and never tans) should avoid exposure to the sun as much as possible.
Put very little sunscreen on. Sunscreen is only effective if it is applied in sufficient quantity to the skin! For example, experts recommend spreading the equivalent of 1 teaspoon per arm, 2 teaspoons for the legs, and a minimum of 1 teaspoon for the face, neck, and décolleté. The presence of a whitish film on the skin is a good indicator. A 50 cl bottle is therefore not supposed to last 2 months, but maximum of 5-7 days.
Forgetting certain parts of the body. Of course, sunscreen should be applied in a generous layer to the shoulders, arms, legs, décolleté and back – areas that are particularly prone to sunburn! However, don’t forget the treacherous areas that can also burn under the action of UV rays: ears, feet (and toes), the top of the face (especially the hairline) and the back of the knees.
Only use sunscreen at the beach or pool. Unsurprisingly, the harmful effects of UV rays do not stop at the edge of the beach or pool! Even when sunbathing in the garden, going for a walk in town or having a drink on the terrace, don’t forget to spread yourself generously to protect your skin. Good to know: some sun products are more suitable for urban use as they leave fewer white marks and look less oily.
Do not look at the composition of your sunscreen. It is essential to take a look at the label of your sunscreen and avoid, as much as possible, products that contain endocrine disruptors: benzophenone (1, 2, and 3), dihydroxy benzophenone, homosalate, octyl methoxycinnamate (OMC), 4-methyl benzylidene camphor.
