To minimize sun damage to the skin, use sunscreen regularly, regardless of the season. But in fact, not everyone knows how to use sunscreen properly: when and what kind of skin really suits him. According to the principle, the SPF 30 filtered 95% of the UV rays and only 60% filtered (only 2%).

An ideal sunscreen is an SPF 20-30 for light and SPF 10-20 for darker complexions. SPF 60-100 SPF should only be used in specific areas to provide optimal protection for the sun-damaged and sun-damaged skin.

To promote full sun protection, users should apply cream before the 30 minutes or can use sunscreen as a foundation cream when the makeup, the amount of sunscreen can be maintained, permeate into the skin and have.
