The "S" in Skincare is for Sunscreen
Ah, our lovely tropical weather with the blazing sun!
It’s not difficult to get a tan in this city and while it might be desirable for some to show off that golden glow, it’s also important to protect ourselves from harmful UV rays.
Dangers of UV Rays
Though the sun might be earth’s main source of life, too much of a good thing can be bad for you. The sun produces ultraviolet radiation, and Singapore is cited to be one of the countries that has the highest levels of radiation in the world (Source: Today Online, 2020).
It is therefore vital for us to protect our skin whenever we are exposed to the sun. We can do so in various ways, and the simplest one is to apply sunscreen.
Sunscreen should be applied anytime you are exposed to the sun, even if you are indoors. You’d need to reapply more frequently if you are engaging in outdoor activities.
What exactly is sunscreen, and is there a difference between it and sunblock?
It’s all about the ingredients, and the more accurate terms to use for sunblock and sunscreen are “physical sunscreens” and “chemical sunscreens” respectively. Here’s another fun fact - they work differently too!
While physical sunscreens act like a layer on your skin and block UV rays, chemical sunscreens don’t. Instead, they absorb the UV rays and expel the resultant small amount of energy as heat.
How do you choose a suitable sunscreen for yourself? A tube of sunscreen may boast features such as “SPF 50” or “PA+++”, but what do these values mean?
-
SPF
- No, this SPF doesn’t stand for Singapore Police Force. SPF in sunscreens refers to “Sun-Protection Factor”, and it helps to confer protection against UVB rays. Does a higher SPF value mean better protection? This video explores the answers.
-
PA+/UVA/Broad Spectrum Protection
-
A rating system that originated from Japan, PA+ is an indicator of the level of a product’s protection against UVA rays. Its European Union equivalent is UVA, which is also referred to as “Broad Spectrum Protection” in the United States.
