1. Choosing The Right Sunscreen Lotion:
Before getting into how to apply a sunscreen, it is essential to choose the right sunscreen lotion first. Check the SPF number which is the abbreviation of Sun Protective Factor which is the way to know the duration of how of long it can block the UVB rays. Sun Protection Factor comes in numbers, i.e. SPF 15, SPF 30, SPF 45 and SPF 60.
But it is important to know that no sunscreen blocks 100% UVB rays.For example, about 94% of UVB rays are blocked by SPF 15, 97% by SPF 30 and about 97% by SPF 45. The type of your skin and your activities should be kept in mind too while you select a sunscreen.

People who have to stay outdoors most of their times should select sunscreen lotions with a higher SPF and they might also need to use it more than indoor people.Since the sun radiates UVA radiations too apart from UVA rays, it is recommended to select a broad spectrum sunscreen lotion.
Signs of ageing, dark or light spots and wrinkles are the damages caused by UVA rays which may lead to skin cancer. So, a sunscreen lotion which prevents both UVA and UVB rays is a good option. Also, it is advisable to choose a water resistant sunscreen lotion because our body expels water in the form of sweat. It is especially very important for active people.
2. Should Do a Trial First:
Once you have bought a lotion, it is always recommended to try a small portion of the sunscreen around your wrist to check if you have any allergic reaction. Read the ingredients in the package to check if you are allergic to any of them before buying. Sunscreen lotions with zinc oxide and titanium dioxide are less likely to cause allergic reactions on your skin.

3. How To Apply Sunscreen Lotion:
Always apply a sunscreen 20-30 minutes before you go out in the sun because the chemicals in the lotion takes some time to bind to your skin. A common mistake while applying sunscreen is not using enough. Take a dollop in to your palm and apply it in the exposed areas of your skin. Rub it well in to your skin so that no white can be seen. Don’t ignore areas like your ears, neck and the tops of your palm and feet.
4. How To Apply Sunscreen Lotion On Face:
Use a facial sunscreen as our face needs even more lotion to protect it against the sun. Many skin cancer occurs on the face and so it is strongly recommended to never leave home without sun block.
5. Re-Apply After 30 Minutes:
If you have prolonged exposure to the sun then you should reapply a sun block within 15-30 minutes instead of waiting an hour or more.
