Olive Young's Best-Sellers in 2026: Worth the Hype?

In Seoul, Olive Young has become a staple for beauty enthusiasts, a one-stop shop where you can find everything from cult-favourite skincare to trendy makeup. As I strolled through the aisles of the Yeonnam-dong branch recently, I couldn't help but notice the buzz around certain products that are often labelled as best-sellers. But how many of these truly live up to the hype? This year, I decided to sift through the offerings and identify Olive Young's top 10 best-sellers that are actually worth buying in 2026.

1. COSRX Hydrium Moisture Power Essence

First up is the COSRX Hydrium Moisture Power Essence, priced at 15,000 won (roughly $12). This essence claims to deliver intense hydration thanks to its unique blend of propolis and vitamin B5. Many users have reported a noticeable improvement in skin texture after consistent use. If you're looking for something to boost your hydration routine, this might be worth a try.

2. Laneige Lip Sleeping Mask

The Laneige Lip Sleeping Mask, available for 18,000 won ($15), is another perennial favourite. It has garnered rave reviews since its launch and for good reason. The formula is thick yet absorbs overnight, leaving your lips feeling soft and rejuvenated by morning. I can't imagine my nighttime routine without it, especially during the dry winter months.

3. Innisfree Green Tea Seed Serum

Next, we have the classic Innisfree Green Tea Seed Serum, which retails for 29,000 won ($24). This serum is formulated with Jeju green tea and is celebrated for its lightweight texture and hydrating properties. While it has a dedicated following, some may find it underwhelming compared to other serums on the market.

4. Etude House Sunprise Water Sun Gel

As summer approaches, sunscreen becomes non-negotiable. The Etude House Sunprise Water Sun Gel, priced at 16,000 won ($13), is a lightweight formula that provides SPF 50 protection without the greasy feel. It absorbs quickly and can be reapplied throughout the day without disrupting makeup. Many expats in Gangnam swear by it.

5. Our Vegan Skin Plant-Based Cleansing Foam

The Our Vegan Skin Plant-Based Cleansing Foam is a newer entry to the market and costs 12,000 won ($10). It promises gentle cleansing with a plant-based formula, which has been a hit among those looking for eco-friendly options. However, its efficacy may vary depending on skin type.

6. Missha Time Revolution The First Treatment Essence

The Missha Time Revolution The First Treatment Essence is often cited as a dupe for higher-end essences and is priced at 30,000 won ($25). It's reputed for its brightening effects and overall skin improvement. Based on personal use, I can confirm that this essence definitely deserves a spot on your shelf.

7. The Face Shop Rice Water Bright Cleansing Oil

This cleansing oil is a hidden gem, priced at 16,000 won ($13). The The Face Shop Rice Water Bright Cleansing Oil effectively removes makeup and impurities while leaving skin feeling nourished. It's become a staple in my double-cleansing routine.

8. Tonymoly I'm Real Sheet Masks

Sheet masks are a must-have for many, and the Tonymoly I'm Real Sheet Masks are not only affordable at 1,000 won ($0.85) each, but also effective. With various options catering to different skin concerns, they provide a quick boost of hydration or treatment without breaking the bank.

9. Holika Holika Aloe 99% Soothing Gel

For those with sensitive skin, the Holika Holika Aloe 99% Soothing Gel at 10,000 won ($8) is a lifesaver. Perfect for calming sunburns or irritation, this gel has been a summer staple for many in Seoul. It’s light, refreshing, and multifunctional.

10. Dr. Jart+ Cicapair Tiger Grass Color Correcting Treatment

The Dr. Jart+ Cicapair Tiger Grass Color Correcting Treatment costs around 43,000 won ($36) and is known for its ability to neutralise redness. While it may be pricier than the others on this list, many users swear by its effectiveness, particularly for those with sensitive or red-prone skin.

Final Thoughts

While each of these products has its advocates, the effectiveness can vary depending on skin type and personal preference. It's important to consider your unique needs before making any purchases. Olive Young's best-sellers often reflect current trends, but not all are inherently essential.
