Of course I am not using the method on children, nor babies

It's adults (sportsmen) only, for obvious reasons!
Elyth is a german brand, produced in Korea (just like most of them), but please let's not turn this into a commercial thread. And you are perfectly right to say that we can find many differences in tapes coming from different brands - I have stated it myself.
My method consists in a BETTER and MORE LONG LASTING ADHERENCE of the tape, and nothing more (therefore - a new way to apply it). It has nothing to do with the pattern the strips are taped! The text above also includes some observations on the elasticity, grip and so on.
I work in all kind of environments (indoors, outdoors, dust, wind, grease, sweat, sebum, humidity etc.), that's why I am looking at other issues than your concerns.
There's no doubt in my mind that working with children's skin need much-much-much more attention and care.
