{"type":"firestarter.listing","listing":{"id":"lst_QFsHN4X8","product_name":"Brilliant Light™","category":"Serum","description":"About This Formula\n\nVitamin C is one of the most studied and most consequential actives available for skin health — supporting collagen synthesis, defending against the oxidative stress that UV and daily pollution accumulate, and addressing the uneven tone and post-inflammatory pigmentation that sun exposure and hormonal shifts leave behind over time.\nThe challenge has always been formulation. Ascorbic acid — the most potent form of vitamin C — is also the most unstable, the most likely to irritate sensitive skin, and the most likely to disrupt the barrier pH in the process of treating the very concerns it is meant to address.\nBrilliant Light was formulated to resolve that tension. A stable, non-ascorbic vitamin C complex in a lightweight botanical gel base — designed for daily use, for every skin tone, without the irritation that conventional vitamin C serums consistently produce in sensitive and reactive skin.\nEsthetician developed. Made without parabens, fragrance, phthalates, or dyes. Sustainably manufactured in the United States.\n\nThe Formulation\n\nBrilliant Light is built around Sodium Ascorbyl Phosphate — a stable, non-irritating form of vitamin C that converts to active L-ascorbic acid after skin absorption, delivering the full brightening and antioxidant benefits without pH instability or barrier disruption.\nAlongside the vitamin C complex, Daisy flower extract and Alpha Arbutin address existing pigmentation and defend against new dark spot formation. Licorice root targets post-inflammatory hyperpigmentation. Gotu Kola supports barrier repair and collagen production. Rosehip seed oil contributes cellular renewal support. And olive squalane keeps the formula compatible with every skin type and tone.\nResults are typically visible within four to six weeks of consistent daily use.\nSodium Ascorbyl Phosphate (Vitamin C) — Stable vitamin C that brightens, supports collagen synthesis, and defends against oxidative stress without barrier disruption.\nDaisy Flower Extr","images":["https://cdn.shopify.com/s/files/1/2234/0215/products/Klur_BL-OnGray.jpg?v=1545274310"],"price":88,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:49.839Z"},"share_url":"https://firestarter.network/l/lst_QFsHN4X8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
