In times of high technology your face is much more exposed to harmful radiation than in times when mankind did not have constant access to electro gadgets. The blue light coming from your laptop, tablet, smartphone or even a regular TV set affects your skin as badly as UV rays. A cream with a high SPF filter should therefore permanently be present in your beautician. Lubricate your face before you sit in front of your computer for hours and you'll see the results after just thirty days.
