PhilosophySugarcane-derived squalane as the house ingredient — clean, biotech-led skincare that avoids the extraction problems (shark liver, olive) of traditional squalane.Minimal, effective formulations at accessible prices. Every product built around one or two proven actives with short, transparent ingredient lists.

Biossance

The squalane oil is a genuinely great single-ingredient face oil and the best argument for the brand. Serums are competent but not category-defining. The 'clean beauty' positioning is better-earned here than at most brands because the biotech story is real. Mid-premium pricing.

Pros

✓ Sugarcane-derived squalane is a real biotech innovation
✓ Solid barrier-focused lineup
✓ Strong sustainability credentials
✓ Squalane oil is the cult hero

Cons

✗ Flagship active (squalane) is widely available
✗ Serums less differentiated than the oil
✗ Premium-tier for clean-beauty positioning

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.
