When combined with fresh, water-activated Vitamin C and mineral-rich salts, the fizzing effect and extraordinary brightening and refining results The Problem Solver and The Clean Dirt are famous for is born.\nIt’s important to note that sodium bicarbonate on its own is alkaline, and the key in formulation is always respect to proportion and integration with other complementary ingredients. Sodium Bicarbonate is an incredible asset to skin when used at a proper ratio and balanced by an acid - in our case, our antioxidant superpower Vitamin C. \nOur formulations are designed to stay within a 4 - 5.5 pH range on a scale of 1-14, with 1 being the most acidic, and 14 being the most alkaline. This can vary slightly due to the natural ingredients from batch to batch, as well as more significantly with the influence of your own water source when blending each fresh treatment. This range is ideal as the outer layer of the skin needs to be slightly acidic to maintain proper skin-barrier function.\nFeatured in: The Problem Solver and The Clean Dirt","images":["https://cdn.shopify.com/s/files/1/0296/7461/products/Ingredient_thumbnail_components_holder_45ac93ea-0a4d-4837-8b38-db28b16fd1ef.png?v=1762200568"],"price":0,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:52.739Z"},"share_url":"https://firestarter.network/l/lst_SoLWogwt","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
