9 Best K-Beauty Products of May 2026: Top-Ranked Across Multiple Platforms
Every month, we analyze the top-selling and highest-rated products across five major Korean beauty platforms — Hwahae, YesStyle, StyleVana, Olive Young Global, and Olive Young Korea — to find the products that consistently rank across multiple sources.
For May 2026, we found 9 products that appeared on 2 or more platforms simultaneously. As temperatures rise and summer approaches, sunscreen has taken over the rankings — five of these nine bestsellers are SPF formulas. Here’s what Korean beauty shoppers are reaching for as they stock up for the warmer months.
Products on 3 Platforms
1. Round Lab — Birch Juice Moisturizing Sun Cream
Appears on: Hwahae #4 (rating 4.60) · StyleVana #6 · Olive Young Korea #12
The most consistently ranked product this month — and a perennial spring/summer favorite. Formulated with birch sap rich in minerals and amino acids, this SPF50+ PA++++ sunscreen delivers strong UV protection with a hydrating, non-greasy finish that doubles as a daytime moisturizer. The fact that it ranks on Hwahae, StyleVana, and Olive Young Korea simultaneously shows how broadly trusted it is among both Korean and international shoppers.

2. Beauty of Joseon — Relief Sun: Rice + Probiotics
Appears on: YesStyle #1 (25,709 reviews) · StyleVana #1
The #1 sunscreen on both YesStyle AND StyleVana — an extraordinary feat heading into summer. With over 25,000 reviews on YesStyle, this rice bran extract + probiotic SPF50+ has earned cult status for its silky finish and non-irritating formula. Its affordable price point makes it easy to reapply generously, which is why it dominates global K-beauty sunscreen sales month after month.

3. Beauty of Joseon — Relief Sun Aqua-fresh
Appears on: YesStyle #6 · StyleVana #4
The lighter, watery sibling of the original Relief Sun — and ideal for the warmer months. Reformulated with rice extract and vitamin B5, the Aqua-fresh version gives a refreshing, non-greasy finish that’s particularly popular with oily and combination skin. Its ranking jump in May reflects shoppers shifting toward lightweight summer-ready textures.

4. SKIN1004 — Madagascar Centella Hyalu-Cica Water-Fit Sun Serum
Appears on: YesStyle #4/#5 · StyleVana #2/#3
The water-light sun serum that started a category. SKIN1004’s Madagascar centella + hyaluronic acid SPF50+ PA++++ is virtually invisible on skin — no white cast, no greasy film, just a fresh hydrating layer of UV protection. Its twin pack continues to dominate the top of YesStyle and StyleVana, making it the go-to “sunscreen that doesn’t feel like sunscreen” for sensitive skin.

5. d’Alba — Waterful Tone Up Sun Cream Purple
Appears on: Olive Young Global #10 (rating 4.7) · Olive Young Korea #9 — ✨ NEW this month
A new cross-platform entry making its debut on this list. d’Alba’s Waterful Tone Up Purple combines white-truffle-infused hydration with a subtle purple tint that neutralizes sallowness and dullness — think of it as skincare and color correction in one SPF. The “purple tone-up” trend is having a major moment in Korea this spring, and d’Alba’s version is leading the charge.
6. MEDIHEAL — Essential Mask Sheet
Appears on: Olive Young Global #1 (rating 4.8) · Olive Young Korea #7
Still the #1 bestseller on Olive Young Global and a fixture on Olive Young Korea. Mediheal’s Essential Mask collection — Tea Tree for trouble skin, Madecassoside for soothing, Collagen for firming — remains the most reliable everyday sheet mask line in K-beauty. Pick up a bulk pack and rotate based on your skin’s needs.

7. beplain — Mung Bean pH-Balanced Cleansing Foam
Appears on: Hwahae #5 (rating 4.63) · Olive Young Global #3 (rating 4.8)
A gentle, slightly acidic cleanser powered by mung bean extract — long a fixture in Korean grandmothers’ beauty routines. Helps control sebum and tighten pores without stripping moisture, making it especially welcome as humidity rises. Frequently recommended for sensitive and combination skin.

8. S.NATURE — Aqua Squalane Moisturizing Cream
Appears on: Hwahae #12 (rating 4.58) · Olive Young Global #8 (rating 5.0)
A lightweight gel-cream powered by squalane and deep-sea water minerals. Long-lasting hydration without the heavy texture — exactly the kind of moisture profile that works for warm weather. Notably, it’s earned a perfect 5.0 rating on Olive Young Global, putting it in elite company among gel moisturizers.

9. Anua — PDRN Hyaluronic Acid Capsule 100 Serum
Appears on: Hwahae #10 (rating 4.61) · Olive Young Korea #15
PDRN’s staying power is real. Two months after its breakout, Anua’s PDRN Capsule serum is still ranking on both Hwahae and Olive Young Korea. Combining salmon-derived polydeoxyribonucleotide with hyaluronic acid capsules, it delivers regenerative hydration in a lightweight texture — proof that the PDRN trend has officially crossed from clinic to daily skincare staple.

May 2026 Trends
Sunscreen season is in full swing. Five of this month’s nine cross-platform bestsellers are SPF — Round Lab Birch, both Beauty of Joseon Relief Suns, SKIN1004’s centella sun serum, and the new d’Alba Waterful Tone Up Purple. As temperatures climb, shoppers are reaching for lightweight, high-protection formulas that layer well under makeup.
Tone-up sunscreens are having a moment. The d’Alba Waterful Purple’s debut on this list reflects a broader Korean beauty trend: SPF that doubles as subtle color correction. Purple cast neutralizes sallowness, while pink and lavender variants boost radiance — a category to watch through summer.
PDRN keeps holding ground. Anua’s PDRN Hyaluronic Acid Capsule serum continues to rank cross-platform two months running, suggesting PDRN isn’t a flash trend but a category that’s settling in for the long haul.
Gentle cleansers and barrier-friendly creams remain core. beplain’s mung bean cleansing foam and S.NATURE’s Aqua Squalane cream — both unchanged from March — show that the K-beauty fundamentals (low pH cleansing + lightweight hydration) aren’t going anywhere.
