To protect our skin we need to use sunscreen daily. - sunscreen should be broad spectrum and non comedogenic. For those who work indoor like prolonged screen
time need extra protection against infra-red radiation. - SPF means sun protection factor is a measure of protection of UVB rays.
Usually SPF above 30 and PA +++ is recommended for daily sun protection. SPF
30 and more gives 96% sun protection from UVB rays.it is necessary to look at PA factor also which shows protection from UVA rays.
If you have dry skin use cream based sunscreen for oily skin use gel based sunscreen. For larger body surface area like hands and legs lotion based sunscreen is used. For face and neck half teaspoon (3ml) and for each arm 3ml sunscreen is used. - It should be applied 30minutes before you go out in sun. sunscreen should be
reapplied every 3- 4hours, there are some preparations which give sun protection for eight hour. For reapplication of sunscreen just clean the face with plain water no need of facewash.
