Get yourself some ConvaTec mouldable flanges from their Esteem Synergy two piece appliance range and also stoma collars.
I had tremendous success by applying the ilex paste to the festering and oozing skin around my stoma, then I applied a stoma collar over the stoma and on top of the ilex paste, followed by the ConvaTec mouldable flange, which I affixes a non-vented self adhesive bag ( the vented bags stained my clothing).
I could easy wear this combination for at least 5 or 6 days, even after bathing, although I did tend to change every 3 to 4 days.
Within 2 to 3 days of applying the ilex paste around my stoma and applying the flange & collar as described, the skin around my stoma was completely healed; I continue to apply the ilex, collar and flange as a precaution until takedown.
The filler paste didn’t work for me, did more harm than good; apparently, it contains alcohol and it stung when applied to my inflamed skin.
Although I never used them myself, I acquired some half moon shaped self adhesive strips, made from a similar substance to that of the ConvaTec Mouldable flanges, which are designed to fill low spots around the stoma.
