Sunscreen Guide: The Basic Of All-Day Sun Protection

Sunscreen Guide: The Basic Of All-Day Sun Protection

All skincare experts and dermatologists seem to agree on the importance of wearing sunscreen daily. There is no doubt that sunscreen is the best invisible protective shield for your skin. Every recommended skincare routine puts sunscreen as the last step.

While absorbing enough vitamin D is essential to maintain a healthy active lifestyle, excessive UV exposure triggers melanin production, which in turn causes pigmentation and dark spots. Additionally, it can intensify existing skin problems, like age spots, wrinkles and blemishes. However, thanks to modern technology, sunscreen can now serve as skincare and makeup. Amazing, right?!? In this article, we will cover the basics of sunscreen to keep you safe from the sun.

The Difference Between Chemical And Physical Sunscreen

Sunscreen formulas fall into two types, chemical and physical. Chemical sunscreen uses active ingredients to absorb the energy of the sun and undergoes a chemical reaction that prevents skin damage from heat. Heat is then be released through the skin into the environment. You will find most chemical sunscreens contain oxybenzone, homosalate and octocrylene. 

On the other hand, physical sunscreens, including F Bright UV Base, are formulated with zinc oxide or titanium dioxidean, inorganic compounds that reflect UV rays away from the skin. It sits on top of your skin without altering your skin composition. Therefore, many dermatologists recommend physical sunblocks to patients who have sensitive or acne-prone skin. It is less irritating than chemical UV-blocking ingredients. 

Sunscreen Score: SPF and PA Ratings

While picking the right sunscreen for your skin type is crucial, you also need to understand the information on the package. You are probably familiar with the Sun Protection Factor (SPF) labels. Generally speaking, the SPF number indicates the ability to protect your skin from UVB rays, which are the radiation responsible for sunburn or tan. An average person requires about 10 to 20 minutes of sun exposure to get tanned. A sunscreen with SPF 30 protection factor can shield the skin from burning for about 30 times longer, which is equivalent to 300 to 900 minutes of sun exposure. Hence, it is important to reapply sunscreen every 2-4 hours for optimal protection. 

Choosing a suitable SPF is just as imperative as picking the type of sunscreen. It is based on your complexion and sun intensity wherever you are. If you have darker skin and are explosed to a low amount of the sun’s energy, choose an SPF 15 or above. If you have fair skin and depending on your activity or destination, get an SPF 30 or higher. If you don’t want to make it too complicated, go by the general rule of selecting a sunscreen that is at least SPF 30 with broad-spectrum. You should then be protected in most circumstances.

The word “Broad-spectrum” is widely used on sunscreen packaging, and it refers to the effectiveness in blocking both UVA (associated with skin aging) and UVB rays (associated with skin burning). However, it is a relatively vague term that lacks clarity and accuracy in UVA protection. 

Japan has a more specific grading system targeting UVA rays and is called the PA rating system, an abbreviation for protection grade of UVA. The system was established using the Persistent Pigment Darkening (PPD) method, in which a higher PPD score can provide you stronger protection against UVA radiation. Instead of indicating the PPD score on the package, the Japanese have converted it into a national scoring system for UVA-blocking effectiveness: from the lowest PA+ to the highest PA++++.
