As summer is approaching, Wishtrend will be bringing to you a special series of articles dedicated to summer. For the first article, we will be talking about sun protection. As many of you know, the sun is our frenemy. While it gives life to us, it also does damage to our skin. The sun also causes a lot of skin problems, to name a few : it accelerates aging,causes pigmentation, overactive sebum secretion, etc.
The Two Different Types Of Sun Filters
In general, there are two types of sun filters used in sun protection products : chemical filters and physical filters.

How To Read Your Sunscreen ?
In most Asian sunscreen, you’ll notice two readings : SPF and PA
SPF : Stands for Sun Protection Factor – a measurement for UVB Protection
PA : Stands for Protection grade of UVA - a measurement for UVA Rays.
What is the difference between UVB and UVA ?
UV rays are divided into three categories based on their wavelength.
- UVA rays long wavelength (320-400nm)
- UVB rays medium wavelength (280-320nm)
- UVC rays short wavelength (280nm and below)
While shorter wavelength are the most damaging to skin, UVC rays and shorter-wavelength UVB rays are absorbed by the ozone layer and never reach the earth. Therefore, UVA and longer-wavelength UVB rays have the potential to cause the most harm to our skin.
UVB is very biologically active but cannot penetrate beyond the superficial skin layers. They usually only reach the skin’s epidermis layer. It is responsible for tanning and burning your skin (sunburn), and makes it look darker ; in addition to these short-term effects it enhances skin ageing and significantly promotes the development of skin cancer. UVB can be reflected by glass.
The relatively long-wavelength UVA accounts for approximately 95 per cent of the UV radiation reaching the Earth’s surface. It can penetrate into the deeper layers of the skin and breaks down collagen in our skin while releasing free radicals and causing DNA changes that can result in skin cancer. UVA rays contributes greatly to skin ageing and wrinkling. For a long time it was thought that UVA could not cause any lasting damage. However, recent studies strongly suggest that it may also enhance the development of skin cancers. Unlike UVB Rays, UVA Rays are not reflected by glass and are let through, so even if you’re indoors, UVA rays can still get to you!
Measuring The Protection Of SPF and PA
The numeric value indicates how long the sunscreen will allow you to stay in the sun before experiencing ‘sunburn’ or the darkening of your skin.
For example :
It takes 10 minutes under the sun for Hyuna to experience sun-burn/sun-tan (reddening or darkening of the skin). If Hyuna uses a sunscreen with an SPF 15, it means that Hyuna is able to protect her skin from the sun 15 times longer. Therefore, by using a sun protection of SPF 15, Hyuna is protected for 10 minutes x 15 (SPF) = 150minutes under the sun.
The PA rating system was developed by Shiseido and has then been used in every Asian sunscreens. It is based on the Persistent Pigment Darkening (PPD) reaction reading after 2-4 hours of sun exposure. PA is a protective level of strength to mark the three PA+, PA++ and PA+++. Theoretically, a sunscreen with a PPD rating of 10 should allow a person 10 times as much UVA exposure as would be without protection (same principle with the SPF example).
For example :
PA+ provides some UVA protection with a factor of PPD 2-4. It protects sensitive skin against low to medium UV radiation.
PA++ provides moderate UVA protection with a factor of PPD 4-8. It offers better protection from UVA rays and can be used by people with normal skin exposed to medium UV radiation.
PA+++ provides good UVA protection with a factor of PPD > 8. It is the strongest grade of UVA protection now available. It is designed for normal skin under very strong or direct UV radiation.
