SPF sun blocks, What spf sun block should i buyUse of Sunblock creams or sunscreens is now popular amongst both male and female sexes. When you go to a dermatologist or cosmetician to have an opinion about better skin care management, they will tell you to use a sunblock whenever you go out in the sun. When you go to a shop to buy a sunscreen, you don’t know what SPF sunblock should you buy?. You fear that an SPF 15 sunblock is nothing in front of SPF 50 or 90 sunblock, then you also worry about the cost of a high SPF sunblock.
Sun rays contain ultraviolet radiations that have the tendency to damage your skin. Our skin has the ability to resist this damage for a few minutes to an hour depending upon the colour of the skin. Dark coloured individuals tend to withstand the sunlight for a longer period of time as compared to a fair coloured individual. White skinned individuals more commonly complain of sun damage, rash, pimples and acne as compared to dark skinned individuals.
Why do the dark colored individuals withstand sunlight better?
Cosmetologist encourages the use of sunblock in adults when they go out in the sun. When you buy a sunscreen or sunblock cream, you see a special value on the pack represented by SPF. You may see various values of SPF, maybe 15, 24, 30, 40, 45, 60 etc. SPF stands for sun protection factor. The higher the value better will be the protection. For instance, a 15 SPF sunscreen when properly applied prevents 93% of radiations from affecting the skin. A 30 SPF sunblock, provide 97% protection, and a 60 SPF provides 98% protection. A sunscreen with more SPF doesn’t worth, as even a 100 SPF, sunscreen doesn’t prove 100 % protection. So it claimed that the difference between the protections of SPF and 30 and higher is negligible.
A sunscreen with SPF of 60 costs much more than SPF 15 sunscreen. So it doesn’t worth buying a sunscreen of SPF 60. Instead, you may choose to buy a sunscreen having SPF of 15 or 30. Those dermatologists who care about the pockets of their patient do prescribe an SPF 15 sunscreen.
What do you mean by proper application of a sun block?
Most of the individuals who go to a store go for SPF 60, 80 or 100 sunblock creams. But this is not much worth buying. If you are much concerned about your skin, I would advise you to buy an SPF 30 sunblock, and learn to apply it properly. That is enough. Greater SPF sunblock creams will not do any more good to you. They will just cost you more money.
