PhilosophyFresh-ingredient, low-waste K-beauty with a radical focus on sustainability and unaged, in-season botanical extracts.Minimal, effective formulations at accessible prices. Every product built around one or two proven actives with short, transparent ingredient lists.

SIORIS

SIORIS is the most genuinely sustainable K-beauty brand I can name. They use freshly-harvested botanical extracts within days of picking, minimize synthetic preservatives, and ship in recyclable packaging. The Time Is Running Out Mist is a hydrating mist with real botanical integrity.

Pros

✓ Genuinely sustainable practices
✓ Fresh-ingredient philosophy
✓ Minimal synthetic preservatives
✓ Beautiful natural packaging

Cons

✗ Shorter shelf life than conventional skincare
✗ Premium pricing
✗ Less stable active ingredient strengths

COSRX

The gateway brand for most people entering K-beauty, and for good reason. COSRX consistently delivers effective, no-frills products at prices that make most Western alternatives look overpriced. Their snail mucin line and BHA products are genuine category leaders. They rarely innovate, but they execute the basics exceptionally well.
