Quick answer: On Sept 14, 2026 Green Science Alliance (Japan) announced a plant-biomass gel polish formulated without TPO, HEMA, or TMPTA, launching Sept 17 on its e-commerce shop. Allergen-aware chemistry reduces irritation risk for sensitive clients. It does not replace custom design time. Pair safer gel with a named, priced nail-print add-on so the chair still sells a look retail cannot finish.
Green Science Alliance’s release is R&D news: Drs. Hirotoshi Umemoto and Ryohei Mori positioned a biomass-derived gel that avoids photopolymerization initiator TPO (restricted in Europe for reproductive-toxicity concerns), HEMA (a common allergen in uncured gel), and TMPTA. Current plant content is about 22–25%, with a stated goal to raise it. That is a real operator story for rooms that already field “is this HEMA-free?” questions.
North American owners should not treat chemistry swaps as the whole menu. Safer base gel answers risk. Custom print answers ticket average. When a guest wants a logo, photo, or micro-art on one nail, the printer clocks minutes the freehand hour cannot, and the price sits on the menu next to the allergen-aware polish line.

Takeaway: Use cleaner gel for trust. Use a priced print add-on for the look only a chair can finish.
