Alongside 10% L-Ascorbic Acid USP it carries Polyamine-DAB, which works on the grenz zone — the thin band between epidermis and dermis where structural support is built. Vivier rates it highest of all eight for both wrinkle smoothing and volume, and it is the only one in the range rated for volume at all. If the concern is loss of structure rather than tone or texture, this is the one.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWhich Vivier vitamin C serum is right for you?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 1 · New to vitamin C, or sensitive skin\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-serum-10\" title=\"Vivier Serum 10 Vitamin C Serum\"\u003eSerum 10\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 2 · Oily or combination skin\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-kine-c\" title=\"Vivier Kine-C Vitamin C Serum\"\u003eKine-C\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 2 · Normal to dry skin\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-c-e-peptides\" title=\"Vivier C E Peptides Vitamin C Serum\"\u003eC E Peptides\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 2 · Dullness and uneven tone\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-radiance-serum\" title=\"Vivier Radiance Serum Vitamin C\"\u003eRadiance Serum\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 3 · Mature skin, multi-benefit\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-quintiserum\" title=\"Vivier QuintiSerum Vitamin C Serum\"\u003eQuintiSerum\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 3 · Moderate to severe hyperpigmentation\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-serum-30\" title=\"Vivier Serum 30 Vitamin C Serum\"\u003eSerum 30\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 3 · Stubborn dark spots, hydroquinone strength\u003c\/strong\u003e → \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/www.hwmedicalspa.com\/products\/vivier-advanced-skin-lightening-serum\" title=\"Vivier Advanced Skin Lightening Serum 2% Hydroquinone\"\u003eAdvanced Skin Lightening Serum\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLevel 4 · Loss of firmness and volume\u003c\/strong\u003e → GrenzCine Serum (this one)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vivier","offers":[{"title":"Default Title","offer_id":32555823956100,"sku":"11-130-ZZ-80073-R","price":295.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0902\/4618\/files\/Vivier_GrenzCine_Serum.webp?v=1704236733","url":"https:\/\/www.hwmedicalspa.com\/products\/vivier-grenzcine-serum","provider":"HW Medical Spa","version":"1.0","type":"link"}
