TMD is a smart, personalized sweat-control device designed for men dealing with excessive underarm sweating. As global temperatures rise due to climate change, sweating is no longer just a personal discomfort—it’s becoming a wider social issue, impacting daily hygiene, confidence, and professional presence. Desk research and User research(76 male) revealed that existing solutions present clear limitations: Botox treatments are costly and socially burdensome, while deodorants often offer insufficient control and require frequent reapplication. TMD uses iontophoresis to deliver botulinum-based and fragrance-infused ampoules directly to the skin. An AI-powered mobile app adjusts intensity and treatment routines based on user preferences, sweat levels, and environmental conditions. TMD helps professionals stay fresh, confident, and composed—especially in high-pressure situations like meetings, interviews, and presentations. It also minimizes reliance on disposable sprays and harsh chemicals, contributing to a cleaner, more sustainable lifestyle in a warming world.
