When it comes to skincare innovation, South Korea consistently sets the global standard. K-Beauty has produced some of the world’s most celebrated sun protection formulas, introduced treatments like the widely discussed salmon sperm facial, and continues to outperform many Western products when it comes to addressing redness, uneven tone, and texture. During a trip to Seoul last year, a visit to Olive Young—often compared to Sephora—felt essential. That stop resulted in over $400 worth of skincare and, eventually, an extra suitcase.
After spending the past 12 months testing nearly every product I bought, the timing feels perfect as Olive Young arrives in New York City. With firsthand experience across categories, it’s now easier to pinpoint which formulas truly deliver and are worth repurchasing. Below is a curated breakdown of the standout products that earned a permanent spot in my routine.
Glass Skin Essentials for Smooth, Luminous Texture
The concept of glass skin originates from Korean beauty culture and refers to skin that looks exceptionally smooth, clear, and radiant. These products focus on refining skin texture, evening tone, minimizing the look of pores, and restoring a plump appearance with lasting hydration.

Sulwhasoo First Care Activating Serum
This luxurious serum immediately shows why it’s considered a K-Beauty staple. Formulated with ginseng extract, it supports skin barrier repair while helping improve brightness through a vitamin C derivative. A blend of traditional Korean herbal extracts enhances hydration, leaving the skin balanced and revitalized after each application.
Peach & Lily Glass Skin Refining Serum
Designed to live up to its name, this lightweight serum enhances daily radiance with consistent use. A single pump helps smooth uneven texture and delivers a soft pearlescent glow. It performs especially well on makeup-free days, giving the complexion a polished, refreshed finish.
Targeted Solutions to Calm Redness
For those dealing with persistent flushing or rosacea-prone skin, reducing redness can be challenging. Alongside lifestyle adjustments and prescription care, these formulas help visibly neutralize skin redness both instantly and over time.
Erborian CC Red Correct
This multitasking formula combines the benefits of a calming serum, SPF protection, and color-correcting pigments. It adapts to the skin upon application, disguising redness while soothing irritation. Its long-term place in my routine speaks to its consistent performance.
Cicapair Sensitive Skin Serum
When skin feels overheated or inflamed, this serum offers immediate relief. Powered by centella asiatica and allantoin, it helps calm irritation on contact while supporting barrier repair. Chilling it beforehand enhances its cooling effect.
Gentle Yet Effective Care for Acne-Prone Skin
K-Beauty approaches acne by prioritizing barrier restoration and hydration rather than harsh treatments. The goal is to calm flare-ups while maintaining skin balance, making these formulas suitable for sensitive complexions.
Innisfree Gentle Retinol & Salicylic Acid Serum
This formula blends salicylic acid with a low-strength retinol to address breakouts without causing dryness. A green tea complex supports hydration, reduces visible redness, and helps strengthen the skin barrier for a more resilient complexion.

Ideal for sensitive, acne-prone skin, this ampoule uses plant-based calming extracts to minimize redness, refine pores, and support overall balance. Its non-comedogenic formula makes it suitable for regular use.
Advanced Serums for Aging Skin Concerns
South Korea is known for its advanced anti-aging treatments, both in-office and at home. For those unable to travel, these serums help address fine lines, uneven tone, and loss of firmness.
Medicube PDRN Pink Peptide Serum
This topical serum uses PDRN technology derived from salmon DNA, paired with hydrating peptides. The formula supports skin regeneration, improves elasticity, and helps even out pigmentation for a smoother appearance.
Haruharu Wonder Black Rice Hyaluronic Serum
With a lightweight, lotion-like texture, this serum targets visible wrinkles through black rice extract and hyaluronic acid. Applied as a spot treatment, it helps create a visibly plumped effect within weeks.
Lightweight Eye Serums That Deliver Results
K-Beauty eye serums are designed to be thinner than traditional creams while still delivering high-performance actives. They focus on smoothing fine lines, improving dark circles, reducing puffiness, and restoring hydration.
CosRx Snail Peptide Eye Cream
Building on the popularity of snail-based skincare, this eye formula uses snail mucin and peptides to brighten and firm the under-eye area. It effectively reduces puffiness without irritating sensitive skin.
Beauty of Joseon Revive Eye Serum Ginseng + Retinal
This eye serum blends ginseng extract with retinal to target dark circles and fine lines. Its lightweight consistency layers smoothly under concealer, making it suitable for both morning and evening routines.
