Sun Protection Myths

The hot summer days are coming, many beauties are beginning to take sun protection measures, all the aggravated sunscreen baby out. I do not know in your sunscreen at the same time will break into the following ten misconceptions! The following will tell you the top ten misconceptions of sun protection!

Sunscreens take effect immediately after application

The real situation: because the effective ingredients in the sunscreen must penetrate to the keratin surface layer, in order to play a long time protection effect, so than must be mentioned in the first 30 minutes before leaving home wipe finished, before leaving home in a supplement, in the use of the dose, each time there must be at least 1 ~ 2 ml of the amount, in order to achieve the best sunscreen effect.

UV rays can heat up

Reality: UV rays do not heat up. For example, when people are climbing a mountain, the higher they go, the cooler the mountain breeze is, and the stronger the UV rays are at that time. Every 1000 meters up, the UV rays increase by 10%. The same is true on the sea: the sea breeze makes you feel cooler, but the UV rays are already extremely strong.

No UV rays on cloudy days

Reality: Clouds provide little to no protection from UV rays, 90% of which penetrate the clouds, except for the dark, heavy rain clouds that block some of the UV rays.

The higher the sun protection factor, the better

Real situation: the higher the sun protection factor of the product, it means that the more sunscreen added, the greater the stimulation of the skin, so if it is normal work, choose SPF15, PA + products can be. If you are playing sports outdoors, you should choose a product with SPF25~SPF35 and PA++. If you are swimming at the beach, you can choose SPF35-SPF50, PA+++.

The more sunscreens the better

Reality: The sun protection you really get is only attributed to the product with the higher sun protection value, so there is no need to use two sunscreens at the same time.

It's okay to forget to apply sunscreen

Reality: Sun exposure is cumulative, so although you only receive sun exposure indirectly, the damage to your skin will accumulate over time, and you may not see the consequences immediately, but over time it will cause tanning, spots on your face, loss of skin elasticity, wrinkles, and aging.

Last year's sunscreen continues to be used

The real situation: sunscreen products placed too long, will reduce the sun protection factor, weaken the effectiveness of sun protection. In addition, foreign imports of cosmetics description below the text, there is usually a bottle cap was opened sign, written above a number and capital letters "M", meaning that after opening the cap to be used up within the month specified in the number. This number is not the same as the shelf life printed on the package when imported, which is often one or two years longer. So when using, we recommend that the former prevails.

Sunscreen does not need to be reapplied

The real situation: sunscreen products in the sun exposure area after a few hours of application, due to the dilution of sweat and other reasons, its sunscreen effect will gradually weaken, so it should be washed away and reapplied in time to ensure the continuation of the sunscreen effect.

You don't need to apply sunscreen if you have a tan

The real situation: the skin is tan after sunbathing, indicating that the skin enters a self-protective state. The thickening of the skin and the production of melanin is a sign that the skin is protecting itself. However, melanin can only partially absorb ultraviolet B and play a role in isolating the skin from damage, but has no function to absorb ultraviolet A. Therefore, when going outdoors, a barrier between the sun and the skin is essential.

Tanning will come back naturally white

The real situation: before the age of 25, the skin darkened by pigmentation or spots, are "reversible", can gradually become lighter. But after the age of 25, the skin will lose its automatic reversibility and can only be restored with the help of whitening products to restore the original skin tone. At this point, you must have patience, because the effect of whitening products must take some time to show up.
