We all know the importance of wearing sunscreen every day. Ultraviolet rays from the sun, which come in two forms – UVA and UVB rays – seriously damage our skin.
UVA and UVB Rays
UVA rays account for up to 95 percent of the UV radiation that reaches surface of the Earth. Although they are less intense than UVB, they are much more prevalent and cause wrinkles, fine lines, and age spots. In other words, they are related to skin aging and make skin look prematurely older. Besides, UVA rays can pass through glass. So, even when you are staying at home or driving, your skin is inevitably exposed to UVA rays. They also pass through cloud, thus you’re affected by them not only on sunny days but also on cloudy and rainy days.
UVB rays are mostly associated with sunburns. Though they cannot pass through glass or cloud, UVB rays tend to impair the epidermis, outer layers of the skin, compared to UVA rays. In addition, both UVA and UVB rays are cancer-causing. Although humankind won’t be able to survive without the sun, you definitely need to keep some distance from it. It is crucial to wear sunscreen to keep your skin healthy.
SPF Rating and PA Rating
The key factor of sunscreen is SPF rating. The SPF rating on a sunscreen bottle stands for the sun protection factor, a measurement of how long the product will protect you from UVB rays. A sunscreen with high SPF would prevent your skin from burning and protect it against damages that might cause skin cancer.
Another factor of sunscreen is PA rating. The PA rating system was established in Japan to inform users of the level of protection from UVA rays. In other words, it is an abbreviation of protection grade of UVA. PA is ranked by + grade – the more +, the higher rank. PA+ means your sunscreen provides some protection, for 2-4 hours, against UVA rays. PA++ provides moderate protection for 4-8 hours, and PA+++ offers the best protection of the three, for more than 8 hours of sun exposure. Unlike SPF rating, not every country utilize this PA rating system.
Sunscreens? Makeup Products with UV Blocking Effect?
Sunlight of this season is especially strong. No doubt, you will feel the need to wear sunscreen every time you go out. However, in summer, at the same time, you would probably want to avoid putting on heavy makeup. It feels really stuffy and what’s more, it often melts off the face. Remarkably, these days, especially in Korea, many face makeup cosmetics contain UV blocking effect. When you look at your dressing table, and you notice that your makeup base or foundation contain high levels of SPF, a question might pop inside your head. Wouldn’t it be okay to skip sunscreen if I use makeup products with UV blocking effect?
The answer is NO. In order to safely protect your skin from ultraviolet rays, you need to apply sufficient amount of sunscreen. Dermatologists recommend to apply 2.0mg/cm2 of sunscreen to guard skin properly. This is similar to the size of a quarter. Do you use that much base makeup product each time? Well, I don’t think so.
Though you came to understand the need to use sunscreen before starting makeup, you might still have remaining questions. For example, applying many different products on your face might have your makeup look cakey. Or maybe you hate the white cast caused by sunscreen that makes the color of your face unnatural.
Inorganic Sunscreen and Organic Sunscreen
Usually, sunscreens that are sold in markets can be divided into two types. First is inorganic sunscreen, and second is organic sunscreen.
Inorganic sunscreen indicates physical sunscreen. It creates a thin barrier between your skin and the sun. Thus, inorganic sunscreen doesn’t absorb into the skin but remains on your skin, reflecting or dispersing the sunlight. On the other hand, organic sunscreen refers to chemical sunscreen. It penetrates the epidermis and dermis, absorbs the sunlight, and prevents it from damaging the skin.
Both inorganic and organic sunscreens have pros and cons. Inorganic sunscreen is hypoallergenic, since it doesn’t penetrate the skin, so young children and people who have sensitive skin can use it without concerns of skin irritation. However, it causes white cast. Organic sunscreen doesn’t cause white cast and spreads smoothly. But it might cause skin troubles as it is composed of various chemical components.
SKIN&LAB Fre C Sun Lotion
So now you would be looking for a sunscreen to use in this season. A sunscreen that efficiently blocks both UVA and UVB, applies thinly and smoothly without white cast, and doesn’t irritate your skin.
I strongly recommend Fre C Sun Lotion of SKIN&LAB. It protects your skin perfectly with UV filter, blocking both UVA and UVB perfectly. Fre C Sun Lotion applies smoothly without any white cast, and at the same time supplies vitamin water to skin. The vitamin water would moisture your skin in this sweltering season. Moreover, highly enriched vitamin can prevent wrinkles or sunburns that might be caused by ultraviolet rays. This sunscreen can also control sebum so that you can feel fresh all day long. Last but not least, Fre C Sun Lotion combined only the benefits of inorganic and organic sunscreens. It is mild but doesn’t cause white cast, and has a smooth texture.
