I’ve tried and tested most brands and this is quickly becoming one of my favorites. Similar to the Ink Eze version, it’s more flexible and stretchy, as well as thin. (Similar to a condoms material) The backing stays on well and best of all, like INkEze I have not had a single client have an allergic reaction. Being thinner however, it can be a little tricky to apply and frustrating at first. (Same issue but maybe even worse with INkEze brand.) It does take a little practice, and seems to work best if you hold the edges and bend it sticky side down to make it more ridged and keep it from sticking to its self. Then have the center of it touch the skin first and apply from the inside out. Once you have it down, it’s easy, so don’t give up too easily, as it is much better than products like Saniderm for multiple reasons.
