It’s most celebrated for its ability to brighten skin, evening tone and helping to minimize discoloration, hyperpigmentation, age spots, and residual scarring from acne or injury.\nFuller’s earth is naturally cooling, bringing relief to inflammation and painful conditions. It is also excellent at balancing sebum secretions, reducing excess oil and stagnation in the skin that contributes to acne.\nFeatured in: The Problem Solver","images":["https://cdn.shopify.com/s/files/1/0296/7461/products/Ingredient_thumbnail_components_holder_cf718555-559f-48d1-aa4b-e4bdf0708b36.png?v=1762200557"],"price":0,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:52.763Z"},"share_url":"https://firestarter.network/l/lst_CM8dySVe","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
