We have 2 brands of anti-wrinkle treatment available at Cityskin.
Brand 1 – The ‘American Brand’ which costs $12 per unit
Brand 2 – ‘The European Brand’ which costs $4 per unit.
You need 3 times as many units of the European brand to have the same effect as the American brand. At Cityskin we tend to prefer the European brand as we feel it lasts longer and starts working quicker.
