Seborrheic Keratosis - home treatment - Eskata

I've just had a new mark on my face diagnosed as seborrheic karatosis (or a senile wart, as they are also unflatteringly called). It's a smallish size now, but I know someone who has one on his back, which has grown to the size of a 50p. Obviously, I'd rather mine didn't grow to that size (or larger!) because of its location.

Has anyone tried Eskata, a new hydrogen peroxide solution that can be used to treat seborrheic keratosis at home? The NHS doesn't remove them anymore and I'm a bit reluctant to pay privately.
