How to choose a sun cream

(3)

When the sun is shining, you feel like getting outdoors and doing some sport!But have you given some thought to protecting your face and body from the sun? To take proper care of you skin, read our guide on how to choose your sun cream and enjoy the sun in safety.

What is sun protection for?

When you protect yourself against the sun, you are protecting yourself against ultraviolet rays. Two types of UV rays pass through the ozone layer:

  • UVBs: which cause sunburn and can be at the origin of skin cancer and eye lesions.
  • UVAs: which penetrate deeper into the skin and cause the skin to age more quickly.

No matter what type of skin you have, you must protect your epidermis against the damage that ultraviolet rays can cause. Sun cream forms a barrier against these rays, without stopping you from tanning. On the contrary, they protect your skin and your tan too!

What is the protection factor?

The SPF (Sun Protection Factor) measures the level of protection that sun blocking products provide against UVB rays. This factor is measured by standardised tests in Europe and gives an indication of how long you can remain exposed to the sun without your skin burning. For example, a factor 50 means that it takes fifty times longer to get sunburnt with the cream than without it. But tests under laboratory conditions do not always take environmental factors, such as water, sand, altitude, perspiration, etc. into consideration. The level of protection depends above all on physical activities, bathing, perspiration and chafing, and is significantly reduced if the product is applied in insufficient quantities. - Sun protection products do not provide 100% protection.

How to choose your sun protection for your type of skin

Everybody's skin is different and, according to its colour (phototype), it is more or less sensitive to the sun.

  • Your skin is very light with lots of freckles. Your skin is very sensitive to the sun, you always get sunburnt and you find it difficult to tan. In the event of moderate exposure in the open air, we recommend a protection factor of 30 or 50+. For severe (on the beach) or extreme (in the mountains or in the tropics) exposure, we recommended an even higher protection factor of50+, such as the Aptonia IP 50+ sun spray.
  • Your skin is fair and sometimes with freckles. Your skin is very sensitive to the sun, you often get sunburnt but you tan slightly. We recommend moderate protection, between 15 and 25 in the open air. You need higher protection, between 30 and 50+, on the beach, such as the Aptonia IP 30 sun spray, and 50+ high protection in the mountains and the tropics.
  • Your skin is light but tans quite easily. You have intermediate skin that only burns in the event of intense exposure. We recommend a low protection factor of 6 to 10 for the open air, moderate protection of 15 to 25 for the beach, and higher protection of 30 to 50+ for the mountains and the tropics.
  • You have tough, olive skin. You tan easily without getting sunburnt. We recommend a protection factor of between 6 and 10 for the open air or the beach, and a protection factor of between 15 and 25 for the mountains and the tropics, such as the Aptonia IP 15 sun spray.

Body care tips:remember your after-sun lotion!

After being exposed to the sun, your skin needs to be rehydrated. After-sun products will nourish your skin and help make your tan last longer. Keeping your skin healthy and hydrated is the key to making your tan last longer.

In addition, these lotions are often refreshing and reduce the feeling of heat due to the sun.

We recommend the Aptonia After-sun lotion.

Remember the essential precautions you must take to enjoy the sun in safety:

  1. Clothing offers the best protection for everyone, and especially for children! You can also use other protective accessories, such as hats, sunglasses and a T-shirt.

  2. Sunburn is dangerous, especially for children. Babies and young children should not be exposed to the sun and heat.

  3. Use sun protection that suits your type of skin.

  4. Renew your sun protection every 2 hours and every time you get out of the water, irrespective of your protection factor.

  5. Avoid direct exposure between 11am and 3pm, which is when the sun is at its strongest.

  6. Don't stay in the sun too long, even if you're using a sun protection product. Sun protection products are not intended to increase your exposure time.

  7. Excessive exposure to the sun presents a serious health risk.Exposure to the sun must be gradual.

  8. Sand, snow and water can reflect more than half of the sun's rays onto your skin.

  9. When at altitude and in the tropics, choose a higher protection factor than your usual one.
