Difference Between Sunscreen and Sunblock

Sunscreen ‘screens’ the sun rays which are falling on your skin and thereby lets some of the ultraviolet rays to get through. Sunblock ‘blocks’ all the sun rays falling on you and thereby deflects all the ultraviolet rays. Sunscreen is in a little more liquid form and hence can be applied easily whereas sunblock is a little thicker (because of the presence of Zinc Oxide) and is hard to spread. Use sunscreen where you need normal day-to-day protection from the sun. If your skin is sensitive or aging and you need a complete anti-aging protection from sunrays, use a sunblock. Use sunblocks for infants playing in the sun. Remember that sunscreen can be washed off easily whereas it is harder to wash off a sunblock. If you are going for a swim and you want your sun protection to stay, use a sunblock. And you will not have to reapply. If you are going to apply a sunscreen, remember to apply it nearly half an hour before going for a swim in order to let it dry. Also you will have to reapply at regular intervals if you are going into water. Remember, if you are going to choose a sunscreen, always choose a ‘broad spectrum’ sunscreen. This will screen both UVA and UVB rays.

  1. good article..i didnt know so much technical stuffs..
    my face is extremely oily and i stay in kolkata..can u suggest me a good sunscreen? i am using the lotus sunscreen gel with spf 20..bt i get tanned everyday..i read the nutrogena sunscreen review here,bt i dont know this brand is available in kolkata or not..

  2. if a broad spectrum sunscreen screens out uva as well as uvb rays, what does it allow to hit the skin to make it still different from sunblock? i guess there are many other rays as well that probably don’t hard the skin as much?

  3. Am looking for ‘broad spectrum’ sunscreen lotion will fda approved/some Main Ingredients listed for sunscreen. Should be SPF 15/30 and has aloe vera, green tea extract in it.
