Sunscreen is a crucial ally in the battle against premature aging and skin damage. As we strive to maintain healthy and youthful skin, understanding the importance of sunscreen is paramount. We'll look at the need for sunscreen, the significance of SPF and PA ratings, the differences between chemical and physical sunscreens, and the benefits of incorporating sunscreen into your daily skincare routine. Along the way we'll recommend our favourite and most effective K-beauty sunscreens.
Why Sunscreen is Essential
UV radiation from the sun poses significant risks to our skin's health. UVA rays penetrate deep into the skin, causing premature aging, wrinkles, and age spots, while UVB rays primarily affect the skin's surface, leading to sunburn and contributing to skin cancer. Sunscreen acts as a shield, protecting our skin from these harmful effects and preserving its youthful appearance.
Understanding Sunscreen Ratings
Sunscreen ratings are denoted by two key factors: SPF (Sun Protection Factor) and PA (Protection Grade of UVA). SPF indicates the level of protection against UVB rays, while PA rating indicates protection against UVA rays. Opting for a sunscreen with a high SPF and PA rating is crucial for comprehensive protection against both types of UV radiation.
As a good rule of thumb an SPF rating of 30 and above is high-protection, while a PA+++ rating or higher is recommended.
Chemical vs. Physical Sunscreens
Chemical sunscreens work by absorbing UV radiation and converting it into heat, while physical sunscreens create a physical barrier by reflecting and scattering UV rays.
Chemical sunscreens tend to be lightweight and blend seamlessly into the skin, while physical sunscreens are often gentler and less likely to cause irritation, making them suitable for sensitive skin.
For affordable, high-protection physical sunscreen try the Etude Mild Airy Finish SPF50 PA+++ or for a chemical sunscreen go for the Etude Mild Watery Light SPF50 PA+++.
Common Skincare Ingredients in Sunscreens
Many sunscreens are enriched with skincare ingredients to provide additional benefits. Ingredients like hyaluronic acid offer hydration, niacinamide helps brighten the skin, and antioxidants like vitamin C and green tea extract protect against free radical damage, enhancing the overall health and appearance of your skin.

Application Stations
Apply sunscreen as the last step in your skincare routine, after moisturizer and before makeup. Be sure to apply it generously to all exposed areas of skin, and reapply every two hours, especially if swimming or sweating. Remember, UV radiation can penetrate clouds and windows, so sunscreen should be worn year-round, regardless of weather conditions.
