Hello, Implovers! Have you ever been confused when choosing sunscreen, with all the numbers and symbols on the packaging? SPF 50, PA++++, UVA, UVB they're all written there, but what do they mean?
Don't worry, you're not alone. Many people still don't understand the difference between SPF and PA, even though these two are key factors in choosing the best local sunscreen that truly suits your skin needs. Let's discuss each one by one!
Let's Get to Know the Sun's Rays First
Sunlight is not entirely bad, you know. Adequate exposure actually helps the body produce vitamin D naturally. But what about excessive exposure? That's what we need to be cautious about.
Sunlight produces two types of ultraviolet radiation that directly impact the skin:
Excessive exposure to both in the long term can also increase the risk of skin cancer. That's why sunscreen is not just an option but has become a daily necessity, especially in tropical climates like Indonesia.
What is SPF?
SPF or Sun Protection Factor is a measure of how strong a sunscreen protects your skin from UVB rays. The number on the packaging indicates two things at once: how long and how much UVB rays can be blocked.
Here's a rough comparison:
SPF 40 | 97.5% |
So, the higher the SPF number, the greater the protection. Although the difference is not significant at high numbers, for daily activities in Indonesia, SPF 30–50 is sufficient.
So, What is PA?
If SPF deals with UVB rays, then PA (Protection Grade of UVA) works to protect your skin from UVA rays — the cause of premature aging and hyperpigmentation.
Unlike SPF, PA is not measured in numbers, but with plus signs (+):
The more plus signs, the stronger the protection against UVA. For daily use in the hot weather of Indonesia, PA+++ to PA++++ is highly recommended.
Both SPF and PA Are Essential
Many people often focus only on the SPF number without paying attention to PA. However, they work differently and complement each other.
SPF without PA means your skin is protected from sunburn but still vulnerable to premature aging. On the other hand, PA without sufficient SPF allows the skin to still get sunburned. Therefore, both are equally needed for comprehensive protection.
Proper Sunscreen Application Tips
To maximize protection, here are some things to remember:
How to Choose the Right Sunscreen?
In addition to considering the SPF number and the number of PA signs, there are other important factors, especially for those living in tropical countries, such as texture and comfort.
Heavy sunscreen, sticky, or leaving a white cast usually discourages reapplication. As a result, skin protection becomes inconsistent.
Ideally, look for sunscreen with a light texture, no white cast, non-greasy, and non-sticky for comfortable all-day wear without any hassle.
One option to try is Implora Perfect Shield Bright Boost Sunscreen SPF 50 PA++++. This local sunscreen comes with a watery texture that is light and quickly absorbed, without feeling sticky afterwards. Formulated with Niacinamide to help brighten the skin, Centella Asiatica for soothing effect, and Ectoin to maintain moisture throughout the day.
What's more, this sunscreen also provides protection from blue light and is free from white cast effects suitable for all skin tones, including tan skin. Its formula is non-acnegenic and non-comedogenic, making it safe for acne-prone skin.
So, now you know, Implovers, the difference between SPF and PA? They each have their roles and are equally important for optimal skin protection. Choose a sunscreen that not only has a high protection number but is also comfortable to wear every day because the best sunscreen is the one you actually use consistently!
