Neurotoxins work by temporarily blocking the nerve signals that cause muscles to contract. When injected into targeted facial muscles, they relax the underlying movement that creates dynamic wrinkles — the lines that form from repeated expressions like squinting, frowning, and smiling. The result is smoother skin, softer features, and a more rested, youthful appearance.

At Masters Medspa, we carry the four top-rated neurotoxins: Botox, Daxxify, Dysport, and Jeuveau. Each has a distinct molecular profile, onset time, and duration — and your provider will recommend the most appropriate formula based on your muscle anatomy, treatment area, and goals. All four are FDA-approved and backed by extensive clinical data.

The units you require depend on the size and strength of your muscles, the thickness of your skin, and lifestyle factors including activity level, metabolism, and skincare routine. Your dose may vary from session to session and evolve over the years. The average dose for the upper face is 50 to 64 units, with a similar range for the lower face and neck. A properly dosed treatment should last approximately four months — if less is used than recommended, efficacy may be reduced to two to three months.

Beyond wrinkle relaxation, neurotoxins are also used therapeutically for trapezius slimming and tension relief (trap tox), jaw slimming and TMJ relief (masseter), and hyperhidrosis — the treatment of excessive sweating in the hands, underarms, and feet.
