PhilosophyRadically transparent skincare — full formula breakdowns, no "proprietary complex" theatre.Minimal, effective formulations at accessible prices. Every product built around one or two proven actives with short, transparent ingredient lists.

Dieux Skin

Dieux is the brand that walks into a product launch and shows you the exact percentages. Charlotte Palermino (ex-Snapchat, ex-Nylon) co-founded it in 2020 on the premise that the skincare industry's "proprietary blend" language is hiding weaker formulations. The Forever Eye Mask alone — reusable silicone, not another pack of disposable patches — is worth the visit.

Pros

✓ Full percentages disclosed on every formula
✓ Forever Eye Mask is reusable silicone (industry-first)
✓ Instant Angel moisturiser is a cult barrier cream
✓ Charlotte Palermino is a genuine industry voice on TikTok

Cons

✗ SKU count is tiny
✗ Pricing is premium for the size
✗ No sunscreen (yet)

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.
