@primallifeorg: Think sensitivity means you can't whiten? Think again. The V5 is different — and not in the way brands usually mean that. No peroxide. The whitening pen uses nano-hydroxyapatite, the same mineral already in your enamel, to lift surface stains while supporting the tooth structure. The dual-light system — blue to enhance whitening performance, red to support gum comfort — does 16 minutes of work while you do nothing. Week one: noticeably brighter. Week four: everyone's going to ask you what's changed. This is the system you wish you'd found years ago. Link in bio.
