Our Pick
DUO
Higher editor rating (8.8 vs 8.7)
DUO
Japan's #1 cleansing balm, full stop. DUO (the parent company is Premier Anti-Aging) has sold over 15 million units of The Cleansing Balm and won six consecutive Cosme Awards — the Japanese beauty industry's most-watched rankings. It's a cleansing balm that claims to do five things (makeup removal, cleansing, exfoliation, massage, primer) and actually delivers on at least three. A cult favourite for a reason.
Pros
- ✓ #1 cleansing balm in Japan — genuine market leadership
- ✓ 5-in-1 efficacy reduces steps without feeling stripped
- ✓ variants for specific skin types (charcoal for oily, matcha for antioxidant, white for brightening)
Cons
- ✗ premium pricing for a cleansing balm
- ✗ the '5-in-1' claim is marketing-forward — it's mostly a great cleanser
- ✗ not available at most Western retailers
Real Barrier
Real Barrier is the kind of brand dermatologists quietly recommend without the hype. Launched in 2015 as ATOPALM's adult-focused line, it's built around one core technology — MLE (Multi-Lamellar Emulsion), a patented way of formulating ceramides, cholesterol, and fatty acids in the same lamellar structure as human skin. The result is a hero Extreme Cream that rebuilds the barrier twice as fast as most ceramide moisturisers in independent testing. Not a brand you buy for a routine — a brand you buy for your most compromised skin days. The Intensive Moisture Essence and Aqua Soothing Ampoule are under-appreciated supporting actors. Real Barrier is Korea's quiet answer to La Roche-Posay Toleriane.
Pros
- ✓ patented MLE ceramide technology is legitimately differentiated and clinically backed
