SUN PROTECTION

With the arrival of summer, sunscreen becomes vitally important. However, very few people (even those who use SPF), are truly well protected. To avoid effects such as spots or dehydration, you must prepare your skin to withstand the sun and high temperatures in a safe, healthy way.

Milva Ariza, our skin expert and a technician with Natura Bissé's training team, answers the most common questions about sun protection. 



What is the difference between
UVB and UVA radiation? 

UVB RAYS - in the short term, they cause redness and sunburn.

UVA RAYS - in the long term, they are responsible for skin aging. 



What is SPF
or Sun Protection Factor?

The Sun Protection Factor indicates the level of protection that a sunscreen provides against sunburns caused by UVB radiation.

SPF does not, however, rate your protection against the UVA radiation responsible for skin aging. 



How do I protect myself from
the UVA rays that cause skin aging? 

UVA/UVB rays are harmful all year long, which means that sunscreen must become an essential step in our daily beauty rituals. To avoid skin aging, choose sun protecting cosmetics formulated with active agents that treat your skin as well as protect it. At Natura Bissé, for example, our sun treatment formulas include Provitamin A and MacroAntioxidants along with Pomegranate Extract, all of which are essential to ensuring younger, healthier skin, fighting the damage caused by free radicals and avoiding cellular oxidation and the appearance of spots and wrinkles. 



What is the best way
to choose an SPF? 

You need to consider:

1. Your skin's phototype (natural sensitivity to sun). The lighter your complexion, the higher the selected SPF should be, and exposure to the sun should be slow and progressive.

2. Ground reflection:

- Water reflects 20% of the sun's rays.
- Snow reflects 85% of the sun's rays.
- Sand reflects from 15 to 25% of the sun's rays. 



How often should I reapply sunscreen? 

Sunscreen should always be applied 30 minutes before sun exposure. You should reapply every 2-3 hours in the case of creams and oils and more frequently if using a gel, since less oily products stay on your skin for a shorter period of time. It is important to reapply your sunscreen after swimming and drying yourself with a towel; heavy perspiration can also accelerate the loss of sunscreen, in which case you should reapply it more frequently.

It is also important to note that the higher the SPF used, the longer the interval before it needs to be reapplied. For example, a sunscreen rated at SPF 30 will last around 30 or 40 minutes. One rated at SPF 50 will last around 50 or 60 minutes. 

¿CADA CUÁNTO TIEMPO DEBEMOS REAPLICAR EL PROTECTOR SOLAR?



Is it important to replace my sunscreen from year to year? 

Yes, especially if it has been opened and has already spent some time exposed to the sun. The filters can lose their effectiveness and the product's protection rate diminishes. 



What is the highest
sun protection rating? 

There is no SPF that offers complete protection. Sunscreens rated at SPF 15 filter approximately 93% of the sun's rays; at SPF 30, they filter around 97%, and one rated at SPF 50 filters approximately 98%. Sunscreens that promise a protection factor higher than 50 must include the (+) sign in their name; according to the Japanese Cosmetics Industry Association (JCIA), this symbol indicates a higher degree of protection. This classification ensures optimal protection against UVB and UVA radiation and is the perfect choice for your face, neck, décolleté and hands. These are parts of your body that tend to be more prone spots and wrinkles.

 

HELPFUL HINTS 
FOR HANDLING THE SUN 

 

Avoid spending a lot of time directly exposed to the sun,
even when using sunscreen. 

Use sunscreen daily throughout the year,
even on cloudy or windy days. 

When you are exposed to the sun, cover your head
with a cap and use good sunglasses. 

 During the summer, avoid sun exposure between the hours of 12 p.m. and 4 p.m. 

Children under 6 months should not be exposed to the sun.
Babies' skin is very sensitive and a very high SPF is recommended. 

At high altitudes and in tropical climates the sun's radiation is much more intense than in other places. Use a very high SPF and reapply it frequently. 

If you are taking medication, check with your doctor before going out in the sun. Certain medications can cause photosensitivity
and promote the appearance of spots
