The truth about your SPF

The truth about your SPF

Techniblock prides itself on being a high quality, high protection brand but a common question asked is "will I still get a suntan if I use a high SPF?"

The answer, of course, is yes because there is no such thing as a complete sunblock.  No sunscreen can completely prevent tanning if exposing skin to the sun for extended periods. The myth persists that lower SPF sunscreens aid tanning while higher SPF prevents it. In reality, tanning depends more on sun exposure time, skin tone, and a sunscreen's UVA blocking capacity than the SPF alone.

Sunbathers often assume they get twice as much protection from SPF 100 sunscreen as from SPF 50 but in actual fact the extra protection is negligible. Properly applied, SPF 50 sunscreen blocks 98 percent of UVB rays; SPF 100 blocks 99 percent.

Another important factor when choosing your SPF is understanding how long you should expose your skin to the sun before topping up your protection.  This is where the "number" comes in.  As a broad measurement, skin exposed to the sun without any sun protection will start to burn after about 10 minutes; applying an SPF of 30 will, therefore, provide 30 x 10 minutes of protection, or about 5 hours.  The higher the SPF, the longer it will last and the more UVB it will block.

What's the best high protection for fair skin?

Techniblock's SPF 50 is a very long lasting and extremely water-resistant sun protection.  The absence of oils and emulsifiers in the formula help to create a robust and durable sunscreen that will continue to protect, even whilst in the water.  It is suitable for fair skin that burns easily, as well as sensitive skin, and offers the maximum protection against UVA currently available within sunscreens. It's light and quickly absorbed, providing an almost transparent barrier against UV rays.
