How to choose the right sunscreen?

Choosing the right sunscreen is one of the most important skincare steps, no matter the season. Whether you're talking about Korean skincare or a Western routine, sun protection remains the best defense against skin aging, pigment spots, and the risk of skin cancer. However, with the multitude of options available—textures, SPFs, mineral or chemical filters—it can be difficult to navigate.

In this article, we'll help you understand the essential criteria for choosing the sunscreen that best suits your skin type, your needs, and your kbeauty routine.

Why is sunscreen essential?

Because it's more than just a holiday product: it's a daily shield . Ultraviolet rays (UVA and UVB) can cause deep cellular damage , even on cloudy days.

• UVB rays burn the skin and cause sunburn.
• UVA rays penetrate deeper and accelerate skin aging .

Using suitable sun protection helps prevent:

• Wrinkles and sagging
• Brown spots
• Inflammatory acne (yes, the sun sometimes makes blemishes worse)
• Precancerous lesions

This is why in kbeauty , sunscreen is the last essential step in any morning routine .

SPF, PA, UVB, UVA… how to find your way around?

SPF (Sun Protection Factor)

It measures protection against UVB :

• SPF 15 : blocks 93% of UVB rays
• SPF 30 : blocks 97%
• SPF 50 : blocks 98%

➡️ In kbeauty, we often recommend SPF 50+ , ideal for daily use, even in the city.

The PA (Protection Grade of UVA)

Indicated on Asian sunscreens, it measures protection against UVA :

• PA+ : low protection
• PA++++ : very high protection

Always choose a sunscreen with PA+++ or PA++++ for a complete shield.

Mineral filters vs. chemical filters

Mineral (physical) filters

• Ingredients: Zinc oxide, titanium dioxide
• Act like a mirror that reflects UV rays
• Suitable for sensitive skin
• Less likely to cause irritation

Disadvantage: sometimes thicker texture, white finish on dark skin.

Chemical filters

• Ingredients like avobenzone, octinoxate, etc.
• Absorb UV rays and transform them into heat
• Smoother, invisible texture, ideal under makeup
• Less visible on dark skin

⚠️ Some chemical filters can be irritating to reactive skin. In kbeauty, they are often combined with soothing agents like centella asiatica or aloe vera to limit the risks.

How to choose according to your skin type?

Oily or acne-prone skin

➡️ Opt for gel , fluid or essence textures, non-comedogenic.

Recommendation: Round Lab Birch Juice Moisturizing Sun Cream – light, non-greasy, soothing.

Dry or dehydrated skin

➡️ Choose a sunscreen with moisturizing active ingredients : hyaluronic acid, panthenol, ceramides, etc.

Recommendation: Beauty of Joseon Relief Sun – creamy yet light texture, nourishes the skin.

Sensitive skin

➡️ Prefer mineral filters and soft textures with calming ingredients like centella or calendula.

Correct application: the secret to real protection

• Apply 1/4 teaspoon to the face
• Renew every 2 to 3 hours in case of exposure
• Think about the neck, ears and eye area

📌 Not applying enough or forgetting to reapply greatly reduces the effectiveness of the product, even with a high SPF.

Frequently asked questions about sunscreens

❌ “I’m not going out, I don’t need sunscreen.”
False: UV rays pass through windows. Even when working remotely, protection remains useful.

❌ “I’m already tanned, I’m protected.”
Tanning is not a shield. It's actually a defensive reaction of the skin.

Not with kbeauty formulations, which are designed to be light and comfortable.
