This tonic works in tandem with your favorite EarthTonics moisturizer (think Mushroom Mylk or Repair Creme) as a hydration magnet that delivers their potent botanical actives even deeper. Notice visibly plumper, clearer, dewier skin with everyday use. \nBeloved by those with reactive & sensitive skin.\n\n\nProbiotic Benefits for your Skin\n\n\n Just like the gut, your skin has its own microbiome — a living network that supports barrier strength, hydration, and inflammation response. Our live probiotics nourish this ecosystem by introducing beneficial strains that naturally crowd out the bacteria linked to irritation and breakouts, helping skin stay balanced, clear, and resilient.\n","images":["https://cdn.shopify.com/s/files/1/0292/9858/9756/files/ProbioticBoostSerum50mlECommSquare.jpg?v=1759870998","https://cdn.shopify.com/s/files/1/0292/9858/9756/files/DSC09142.jpg?v=1760447576","https://cdn.shopify.com/s/files/1/0292/9858/9756/files/DSC09046_1.jpg?v=1760447595","https://cdn.shopify.com/s/files/1/0292/9858/9756/files/DSC09166.jpg?v=1760447609"],"price":62,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:53.898Z"},"share_url":"https://firestarter.network/l/lst_5sR0wDkM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
