Hi Xeon.
PSB (TL 400) is .06mm. New Generation (TL 700) is .02 to .03 mm---that's really thin!! This this the thinnest skin available. Using a mist of alcohol on the glue or tape before you apply the skin unit is the best way to go. It will evaporate. After to put the glue or tape on and you spray a mist of alcohol on your scalp the put the base down and gently pull the base outward in all directions to smooth out any ripples. No need to stretch it--just gently pull to make sure that the ripples are smoothed out. The alcohol will evaporate and the unit will stay exactly where you left it.
Regards,
John
