How soon will I see results?
Most people notice a fresh, calm glow right after the very first 10-minute session. Visible changes typically build over 4–8 weeks of consistent use — three to five evenings a week. Light therapy is cumulative, so consistency matters more than intensity.How long does the battery last?
Merkle Radiance is fully cordless. A single USB-C charge covers about a week of daily 10-minute sessions, and it recharges in roughly 90 minutes. The charging cable is included.Is it safe for my eyes?
Yes — the mask has shielded eye openings and uses non-UV light. Keep your eyes closed during sessions for comfort. If you have a diagnosed eye or light-sensitivity condition, or take photosensitising medication, check with your doctor first.What's included in the box?
The Merkle Radiance LED mask, a USB-C charging cable, and a quick-start ritual guide — beautifully packaged, ready to gift or keep.How long does shipping take?
You'll get a tracking link as soon as your order ships. Delivery typically takes 7–12 business days, depending on your location. Any questions about your order — just email us and a real person will help.Can I use it with my skincare?
Yes — just in the right order. Use the mask on clean, bare skin, then apply your serums and moisturiser afterwards, when skin is most receptive. Avoid wearing active ingredients (retinol, acids) underneath the mask itself.How do I clean it?
Easy — wipe the inside of the mask with a soft, slightly damp cloth after use, and let it air dry. Don't submerge it in water. That's it.
