Okay, I’m guilty of this but I learned my lesson and I think you should too.
When I was young, I got into a lot of extra lessons in schools that need tend to have their lessons outdoors.
Being a young teenager and I’m into a bit of beauty products, I soon discovered that the importance of using sunscreen as a protection against UV rays. Being a student also means a tight budget too (you won’t see me in ‘rich kids of Instagram’, of course) so I tend to use a tiny little drop of sunscreen whenever I’m having outdoor classes. The result; my skin still burn. So what gives?
The reason is simple, the tiny amount is simply not enough to provide adequate protection for my skin from sun rays and it’s after effects.
It’s because the SPF factor tested in sunscreens uses an application rate of two milligrams of the amount for every square centimetre of our skin – roughly a quarter of teaspoon for an average size face and neck, half a teaspoon per arm, and a teaspoon for chest, back, and legs; what FDA approves and encourage for us to maximise the potential of our sunscreen.
But keep in mind, since the efficacy of the sunscreen varied from brands to textures even within the same SPF value, and coupled with broad-protection label, simply applying the sun ray-protector liberally and generously is essential to provide you the sun-protection that you need.
And the measurement is used for sunscreen made into lotion so if you use a powder, spray or in combination of other skin care/makeup products, it makes sense to use more.
Hence generally speaking, the higher the SPF, the better protection and the longer you can stay out in the sun – though I don’t really recommend it, saves it for unexpected situation, please.
Unlike other stuff, you can’t really be stingy with sunscreen. A good dose of sunscreen will provide a protective layer on the skin without any loopholes and uneven coverage. And not to worry, it’s very unlikely that we apply to much of sunscreen, it’s usually the other way around.
The same rule applies if you want to use a sunblock (also known as physical blocker as it literally blocks the sunrays with the key ingredients of titanium dioxide and zinc oxide) or a sunscreen.
