Sunscreen is an important part of a skincare routine. Even a few years ago, many people only used sunscreen during the summer months, whereas daily sunscreen use is much more common today. One of the reasons for this change is that it is now easier to find lightweight, non-greasy formulas that provide a high level of protection for all skin types. Another reason is the growing awareness of how sunscreen helps protect the skin from photoaging.
In the OEB skincare method, sunscreen is one of the most crucial steps in your morning routine. You can use a variety of treatments containing active ingredients such as vitamin C, peptides, or collagen, but their benefits will be limited if your skin is exposed to daily UV radiation without the protection of sunscreen. That’s why it’s important to remember to apply sunscreen regularly and reapply it as needed throughout the day.
Round Lab sunscreens are among the most popular choices for consumers. It’s no surprise, as the brand has won numerous awards at Olive Young and received recognition from other retailers and online rankings in Korea and around the world. The inspiration behind Round Lab’s products comes from ingredients that can be naturally found in Korea, such as birch sap and camellia. The brand excels at combining nature-inspired ingredients with innovative skincare technology, which is why Round Lab was selected as OEB’s Brand of the Month.

Why Choose a Round Lab Sunscreen?
Round Lab has become a global K-beauty phenomenon, with multiple Olive Young Award-winning products, including the iconic Birch Juice Moisturizing Sunscreen and the bestselling 1025 Dokdo Toner. The brand is known for creating products that effectively meet the skin’s needs, and this is particularly evident in its sunscreen lineup, which continues to be a favorite among customers.
The Birch Juice sunscreen line is the brand’s most well-known range. With this collection, Round Lab set out to create sunscreens that suit a wide variety of skin types and concerns. However, that doesn’t mean the brand has stopped surprising consumers with new, high-quality sunscreen innovations.
Is suncare really that important?
The simple answer is yes. Suncare is an essential part of a well-aging skincare routine. Daily sunscreen use can help reduce the risk of skin cancer and DNA damage, both of which contribute to photoaging. That’s why it’s beneficial to learn about UV protection and start using sunscreen early, but it’s never too late to begin.

If you’re dealing with dark spots, I have good news for you. Sunscreen can help protect your skin from the formation of new pigmentation. Ultraviolet light stimulates pigment-producing cells in the skin to produce melanin, which can lead to dark spots and uneven skin tone. Think of sunscreen as a shield that helps protect your skin from UV rays and the damage they cause.
Whether you’re in your early 20s, 40s, or 60s, sunscreen deserves a place in your daily skincare routine. For mature skin, sunscreen is arguably the single most important skincare product you’ll apply each morning. UVA rays penetrate deep into the skin where they gradually break down collagen and elastin, contributing to wrinkles, sagging, and pigmentation. Daily sunscreen helps protect the progress you’re making with every other step in your skincare routine.
There are many excellent Korean sunscreens to choose from, but if you’re looking to try one of the most popular sunscreen brands in Korea, Round Lab is one of the best brands to consider.
How to Choose the Right Round Lab Sunscreen
While all three Round Lab sunscreens offer SPF50+ PA++++ broad-spectrum protection, each formula is tailored to address different skin types and skincare concerns.
ROUND LAB Birch Juice Moisturizing Sunscreen
It can be difficult to find a sunscreen that provides long-lasting hydration while maintaining a dewy finish. Birch Juice Moisturizing Sunscreen is Round Lab’s most iconic sunscreen, and it’s easy to see why. This sunscreen was the No. 1 winner at the Olive Young Awards for five consecutive years.
The combination of Uvasorb HEB and Tinosorb M delivers a high level of sun protection without making the formula feel heavy, and it leaves no white cast. Birch sap is the star ingredient, while ascorbic acid and tocopherol provide antioxidant benefits that help protect the skin from UV-induced damage.

Recommended for: Dry and normal skin types.
ROUND LAB
Birch Juice Moisturizing Sunscreen
ROUND LAB Birch Juice Moisturizing Sun Serum
If you’re looking for a lightweight sunscreen that layers well under makeup and suits combination to oily skin, Round Lab Birch Juice Moisturizing Sun Serum is a great option. The formula combines birch sap, vegan-friendly PDRN, and hyaluronic acid to deliver lasting hydration without feeling heavy. It leaves no white cast and uses Ecamsule, Uvinul A Plus, and Tinosorb S to provide broad-spectrum UVA and UVB protection. Its lightweight texture feels more like a skincare product than a traditional sunscreen.
Recommended for: Combination & oily skin types.
ROUND LAB
Birch Juice Moisturizing Sun Serum
ROUND LAB Camellia Deep Collagen Firming Sun Serum
This sunscreen has already been featured on OEB, and for good reason. Round Lab’s Camellia Deep Collagen Firming Sun Serum is a multifunctional formula that not only protects the skin from UV rays but also supports your anti-aging routine. While collagen is one of its key ingredients, the real standout is Granactive Retinoid – an advanced retinoid technology known for being effective yet less irritating than traditional retinoids.
Camellia Deep Collagen Firming Sun Serum also embraces the cooling skincare trend that has recently gained popularity in Korea. The micro-cooling capsules help cool the skin and reduce excess heat, making this sunscreen especially refreshing during the summer months.
Recommended for: All mature skin types, especially if you want to target skin-tone concerns.

Round Lab Sunscreens FAQs
How does the Korean Round Lab sunscreen different to the US version?
The main difference lies in the UV filters used, as they can significantly affect a sunscreen’s texture and performance. The FDA has not approved many of the newer UV filters commonly used in Korean sunscreens, although the FDA has recently begun reviewing newer UV filters that have long been used in other markets. As a result, there can still be noticeable differences between the Korean and U.S. versions of Round Lab sunscreens.
That said, the U.S. versions are still effective options – after all, any sun protection is better than none. However, differences in UV filters may affect factors such as white cast, texture, and overall skin feel, so it’s worth keeping that in mind when shopping for Round Lab sunscreens in the United States.
Are Round Lab sunscreens suitable for sensitive skin?
In general, yes. All three formulas are free from essential oils, added fragrance, and colorants, making them suitable for most sensitive skin types. However, because they rely on chemical UV filters, some people with highly reactive skin may still want to patch-test them before use.
Which Round Lab sunscreen is best?
It all depends on your skin type. If you have dry to normal skin, Round Lab Birch Juice Moisturizing Sunscreen is likely the best choice. Those with a combination to oily skin may prefer the lighter Birch Juice Moisturizing Sun Serum. For mature skin, Round Lab Camellia Deep Collagen Firming Sun Serum stands out as the best option, as it is a multifunctional sunscreen designed to provide UV protection while also targeting wrinkles and dark spots.
