Contrary to popular belief, it is not necessary to reapply sunscreen every two hours.
Sunscreens gradually lose their effectiveness through exposure to direct sunlight, NOT with the passing of time.

Over the course of your typical day in the city — such as a workday — the sunscreen applied in the morning will be able to provide sufficient protection until sunset. That is, of course, assuming that you have applied enough sunscreen in the morning and that your daily activities take place mostly indoors. Hemeryne comes up exactly with the right amount of product you need for the entire day for your face and neck, so that you don’t have to worry.

If you are looking for the perfect ally for your urban life, without worrying too much, you’ve come to the right place.
