How to use sunscreen

Hello, everyone how are you all? I am doing well and hope you guys are doing great today i am gonna share tips to use sunscreen which also known as sunblock is a lotion,spray,gel or other topical product with SPf that absorbs or reflects some of the sun's ultraviolet radiation and thus helps protect against sunburn.                                                                                                                                                                SPF or sun protection factor is a measure of how well a sunscreen will protect skin from UVB rays, the kind of radiation that causes sunburn,damages skin and can contribute to skin cancer.                                   For best protection ,experts recommend using a minimum SPf sunscreen of 15,applying the proper amount (2mg) of skin,or about one ounce for full body coverage and reapplying every 2 hours.                     The SPF(sun protection factor) scale is not linear-   
 *SPF 15 blocks 93% of UVB rays 
 *SPF 30 blocks 97% of UVB rays
 *SPF 50 blocks 98% of UBV rays
so, one of looking at this is that SPF 30 sunscreen only gives you 4% more protection than SPF 15  sunscreen. its complicated ,but to keep it simple most dermatologists recommend using a SPF 15 or SPf 30 sunscreen. according to dermatologist most people don't follow the right direction to apply sunscreen.
by wearing sunscreen correctly and daily you'll not only prevent scorching your skin, you'll also help prevent sun damage ,lessening your dependence on those skin repairing or anti ageing beauty products.
When to apply sunscreen -
Apply sunscreen approximately 30 minutes before being in the sun (for best)so that it can be absorbed by the skin and less likely to rinse off when you perspire.remember to reapply sunscreen after swimming or strenuous exercise.
How to apply sunscreen-
*Shake well before use to mix particles that might be clumped up in the container consider using the     new spray on or stick types of sunscreen.
*Dot sunscreen directly onto your face instead of squeezing a gait blob onto your hands and applying it.
*Put on sunscreen on first then your moisturizer 
*use zinc oxide if you need immediate sun protection both zinc and titanium dioxide are minerals that block the sun's Uv rays ,so they work faster than chemical sunscreen ingredients, which must be absorbed n to convert light to heat energy in your skin.
