Q: What makes Korean skincare different from Western skincare?

Korean skincare focuses on prevention, hydration, and skin barrier health — not just treating problems after they appear. The routines are layered (lightweight to rich), and the formulas use ingredients like snail mucin, PDRN, and fermented extracts that aren't common in Western products. It's skincare as a long-term habit, not a quick fix.

Q: I'm a beginner — where do I actually start?

Start with just three steps: a gentle cleanser, a hydrating toner, and an SPF. Once your skin is balanced, you can layer in serums or treatments. We recommend starting with COSRX or Anua — both are beginner-friendly and work for most skin types.

Q: Where do you ship?

We ship throughout the United States with free shipping on orders over $30. Standard delivery is 5–7 business days via USPS, with tracking included on every order. We currently focus on the US market only.

Q: What is PDRN and why is everyone talking about it?

PDRN (Polydeoxyribonucleotide) is a skin-repair ingredient derived from salmon DNA. It helps with skin regeneration, fine lines, and uneven texture. Think of it as a next-level alternative to retinol — without the irritation.

Q: Are your products authentic? Where do you source them?

Yes — 100% authentic. We source directly from authorized distributors. Every product sold on Llusso is the same formula you'd find in Korea.
