Tones' HEMA & TPO Free collection includes 100+ professional nail products — gel polishes, rubber base gels, UV/LED top coats, cat eye gels, color corrective gels, and fashion builder gels — all formulated without HEMA (Hydroxyethyl Methacrylate) and TPO (Trimethylbenzoyl Diphenyl Phosphine Oxide), the two most common allergens and sensitizers in the nail industry. Designed for nail technicians and salons serving clients with sensitivities, every product in this line delivers the same salon-quality performance Tones is known for — minus the ingredients linked to contact allergies, skin sensitization, and long-term reactions from repeated professional exposure.
