KC.....if you're concerned about ilex sticking to hairs back there, then I assume your butt burn is either not severe or maybe non exsistant.
If you do have severe butt burn, kind of red raw, stings to touch, excruciating pain during a bowel movement and a rash similar in appearance to the diaper rash that babies suffer from; then the ilex Paste has to be liberally smeared over the affected area and reapplied without removing what was applied previously, that is, until the ilex begins to fall off all by its self , either when wiping or at any other time.
When the ilex does detach from the skin, it's best to peel it all off and reapply if still needed.
When ilex has been appllied liberally, it will feel like a sticky mess and only wet wipes will cleanse sufficiently whilst the ilex remains applied. I've never used Vaseline, only ever used pure non scented wet wipes to cleanse.
When I say cleanse; what I really mean, is wipe.
If butt burn has not occured and ilex is applied as a preventative measure, then only a very small pea size amount of ilex need be applied, just around the opening and between the cheeks, either side, such an amount will not require Vaseline over it and will not clump up or feel sticky.
Wet wipes are best used for cleansing as toilet paper tends to rip against the ilex.
When ilex has been applied sparsely over the affected area, on occasions, it will be necassary to remove small clumps/beads of dried up ilex by pinching them off with a wet wipe or toilet paper.
As for applying ilex internally, it states on the ilex tube & box..... For External Use Only; although, I've been applying it internally to an anal fissure.
I apply it internally for maybe two or three days, probably every few months, the moment I feel the slightest feeling of internal itching or a burning sensation.
I've been applying ilex internally, on and off for years and without adverse effect.
