Question about Ardell 1 Step Gel Polish Refined 10 ml

Based on the manufacturer's official product listings and ingredient information available, this product does not appear to be specifically marketed as TPO-free. The ingredient list does not mention trimethylbenzoyl diphenylphosphine oxide (TPO), but this does not guarantee absence, as some manufacturers may use alternative names or related compounds. For absolute certainty, please contact Ardell customer support directly with the product code to confirm TPO status.
