Quiet the muscles behind the lines.
Botulinum toxin type A is a purified protein that temporarily relaxes overactive muscles. Because many expression lines are shaped by repeated movement, softening that movement may ease forehead lines, crow's feet and frown lines over time. Health Canada authorizes specific products for specific uses, so the product name on the vial matters.
You may also hear about variations. SkinTox uses a diluted, superficial placement that many clients explore for oil and the look of pores. Barbie Tox or TrapTox targets the trapezius for a slimmer neck-and-shoulder line or tension relief, and CalfTox is used for calf contouring. These are outside standard labelled uses, and a practitioner decides whether they suit you. Please discuss your options with a licensed practitioner at a partner spa.
