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-favorite skincare to trendy makeup. While recently wandering through the aisles of the Yeonnam-dong branch, I noticed the ongoing buzz around certain products often labeled 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. Users have reported noticeable improvements in skin texture after consistent use. If hydration is what you're after, this could be a worthy addition to your routine.

When testing this essence, I found it absorbs quickly and layers well under other products. It’s particularly effective when paired with a heavier moisturizer to lock in the moisture. If you have oily skin, you might appreciate its lightweight feel, while those with drier skin may find it complements their regimen nicely.

2. Laneige Lip Sleeping Mask

The Laneige Lip Sleeping Mask, available for 18,000 won ($15), is another perennial favorite. Since its launch, it has garnered rave reviews, and for good reason. The formula is thick yet absorbs overnight, leaving lips feeling soft and rejuvenated by morning. It's a must-have, especially during the dry winter months.

Many users in Seoul swear by the different flavors, with the original berry being the most popular. However, the vanilla and grapefruit options have their own dedicated fans as well. If you’re wondering how to get the most out of it, applying a generous layer before bed and reapplying it in the morning can really boost the benefits.

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 made with Jeju green tea and is celebrated for its lightweight texture and hydrating properties. While it has a dedicated following, some might find it underwhelming compared to other serums on the market.

In my experience, this serum works best when applied on a slightly damp face to help lock in moisture. It’s a great option for those who prefer a simple routine, but it may not be potent enough for people seeking serious anti-aging effects or intense hydration.

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, making it easy to reapply throughout the day without disrupting makeup. Many expats in Gangnam swear by it.

For those looking to layer it under makeup, it has a matte finish that works beautifully with BB cream or foundation. If you have oily skin, this could be a game-changer, as its water-gel texture doesn’t leave a heavy residue.

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 eco-conscious consumers. However, its efficacy may vary depending on skin type.

Many users have found it effective for daily cleansing without stripping the skin of moisture. It’s particularly suitable for those with sensitive or combination skin. For maximum benefit, pairing it with a cleansing oil for a double-cleansing method can yield great results.

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 various user testimonials, this essence deserves a spot on your shelf.

To incorporate this into your routine effectively, apply it right after cleansing while your skin is still damp. Many beauty enthusiasts recommend using a cotton pad for application, as it allows for more even distribution. This product can easily replace more expensive essences, making it great for those on a budget.

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 has become a staple in many people's double-cleansing routines.

When using it, a little goes a long way. Massage it into dry skin, then emulsify with water for easy removal. It’s gentle enough to use daily, making it suitable for all skin types, even those prone to breakouts.

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.

These masks are easily obtainable in multiple flavors targeting everything from hydration to brightening. For those new to sheet masks, it’s best to start with a hydrating option like the "Moisture" or "Hydrating" variants.

9. Holika Holika Aloe 99% Soothing Gel

For those with sensitive skin, the Holika Holika Aloe 99% Soothing Gel, priced 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.

This gel can be used in various ways, from after-sun care to a moisturizing agent for oily skin. For an extra refresh, store it in the refrigerator. Users often report that it helps soothe redness and inflammation effectively.

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 neutralize 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.

For optimal use, apply a small amount to areas needing correction. It can be layered underneath foundation or worn alone for a more natural look. If you're dealing with rosacea or frequent redness, this product might become a crucial part of your routine.

Final Thoughts

While each of these products has its advocates, effectiveness can vary depending on individual skin type and personal preferences. 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.

As we move further into 2026, I plan to explore the emerging beauty trends shaping K-beauty this year. Have you stumbled upon any products or trends that surprised you? What have your experiences been with these best-sellers? Let's discuss.
