But there are other ways that are also effective to protect your skin, use sunscreen that is also known as sunscreen or sunblock that contains UV protection. How you can choose an effective sunscreen? Here are some tips on choosing an effective sunscreen.


Many people do not wear enough sunscreen for cosmetic reasons and the economy. They just put a little sunscreen so it does not reach the solar protection factor (SPF). What is SPF? Then usually in sunscreen products also contained some of the terms or labels such as sunscreen, sunblock, SPF, UVA, UVB, PABA, waterproof, and others. What does it mean? Here is some explanation of terms contained in sunscreen products or sunscreen.

  • SPF
    SPF stands for Suncreen protection factor or protective factor from the sun. Every cosmetic and sunscreen products usually include a number that indicates the level of SPF, such as SPF 15, SPF 30, and so on. SPF levels determine the safe time for your skin exposed to sunlight. For example a sunscreen with an SPF of 15 means your skin will be protected for 15 times longer than the natural resistance of your skin. If you usually experience skin redness after 10 minutes then bask in the sun wearing SPF 15 sunscreen, your skin is safe for 15x10 minutes of 150 minutes.

  • SPF numbers are available from 2 to 60. But it does not mean the higher the SPF number will work according to a multiple of that number. The fact that there is SPF 50 just to give more protection around 1% to 2% compared to SPF 30. The thing to remember is the SPF only applies to protect against UV-B radiation alone.

  • UVA and UVB
    Ultraviolet rays that enter the earth within a radius of A, B and C (UV-A, UV-B and UV-C). However, UV-C can be inhibited effectively by the ozone layer. While UV-A and UV-B can enter the earth's surface even though it has been filtered by the earth's atmosphere.

  • Sweatproof
    Sunscreens labeled sweatproof usually resistant to sweat, so it does not fade with sweat.

  • Water resistant
    Sunscreen that has a water resistant labels can provide protection up to 40 minutes if exposed to water or sweat.

  • Waterproof
    Sunscreen that has a waterproof label can provide longer protection than a sunscreen that is labeled water resistant up to 80 minutes if exposed to water or sweat. Suitable for use if you're swimming.

  • Sunblock
    Sunblock is a type of physical sunscreens that function block or reflect sunlight through the skin surface. Physical sunscreens often contain zinc oxide or titanium dioxide which serves UV radiation. However, only sunblock can prevent UV-B rays.

  • Organic Sunscreen
    Organic sunscreen is a sunscreen chemical species whose function is to absorb or filter out ultraviolet radiation (UV). Chemical sunscreens often contain such octylcrylene, avobenzone, octinoxate, octisalate, oxybenzone, homosalate, 4-MBC, or para-aminobenzoic acid (PABA). Sunscreen can provide more protection than a physical sunscreen because it can absorb UV-A radiation and UV-B. UV-A radiation penetrates the skin more deeply than UV-B, which can cause skin cancer.
