People with oily skin can use gel based sunscreens. While people with normal skin can use both gel based as formed as well as in lotion form. The people with dry skin should use Sunscreen in cream form.
How you can assess the efficiency of Sunscreen?
Here we have to take care of two things.
1. Star rating
** means medium efficiency.
*** means high efficiency.
**** means higher efficiency.
2. SPF (Sun Protection Factor)
It is the protection against UV visible rays.
- SPF 15 – 93% protection.
- SPF 30 – 97% protection.
- SPF 55 – 98% protection.
Should we apply SPF-50 instead of SPF-30 just for 1% protection?
Well yes, every bit of protection matters.
Can there be a drawback of using higher SPF?
Some people can get false sense of security. That if they are applying higher SPF they are invincible. But that’s not the case. A Sunscreen can provide a basic protection. However if you want full protection avoid sun in the peak hours from 11 a.m. to 3 p.m. In this time period wear sun glasses and sun clothes that covers your body from Sun.
How much quantity of Sunscreen should you apply?
Quantity of Sunscreen is really an important factor for determining the degree of protection. You must apply 2 to 2 ½ finger tips on a face nick spread it evenly on your face.
- You must apply it 15 minutes before going into the sun. Reapply it after every 3 to 4 hours.
Should you apply Sunscreen when sitting indoors?
Definitely yes, UV radiation can penetrate through all kind of glasses and can penetrate deep into your skin and can cause photo aging. So must apply it in the indoors.
