Q1. What's the difference between this and the Collagen Booster Gel?
A. Collagen is the glow-and-hydration base for everyone; Peptide is the firming step. If your main concern is skin that looks less firm — jawline, cheeks, underthe eyes — start here. Many people use Collagen in the morning and Peptide at night.
Q2. What does 'contour lift up to 17.8%' actually mean?
A. In a two-week clinical study, contour lift improved by as much as 17.8% in the best-responding participant; results across the group varied.* We publish thehonest number, not the headline one.
Q3. When will I see a difference?
A. A resilient, dewy feel on day one. Firmer-looking contours typically show from week two with daily use — faster when you pair it with two or three minutesof upward gua sha.
Q4. What are the pink capsules, and does the gel feel sticky?
A. Peptide capsules that break as you massage. Like all Booster Gels, it's rich on touch for the first 3–5 minutes, then melts in weightless — use a dime-sizeamount and don't wipe.
Q5. Is it suitable for sensitive skin?
A. It scored 0.00 on a primary skin irritation test and contains centella and ceramide NP for comfort. Unscented, no added fragrance. Patch-test if you'rereactive.
Q6. How do I use it with gua sha or a device?
A. Apply, then sweep upward and outward along the jawline, cheeks and forehead. Reapply a touch if the tool starts to drag. It also conducts with microcurrentdevices.
Q7. Is it vegan and cruelty-free?
A. Yes — certified vegan and cruelty-free, made with Kolmar Korea under GMP-certified manufacturing.
