I haven't heard of that product. I've been a part of this forum for probably about two years now and I believe it is a general consensus that you should just leave the shed alone. Sometimes, if there is retained shed, I've helped ease it along using a soft/wet toothbrush. I suggest just giving your beardie more baths during this time, to keep them
hydrated even more, it will help the shed move along. If it's warm outside, bring them outside as well and let them soak up some of those natural UV rays.
