brown saging skin at bottom of old grafted scion

[SirLSD]

this graft, and one other (same source) have always had this brown sagging soft skin at the base. it seemsthat the cacti produces new skin faster than it grows. as new skin is made the old skin collects at the base where it goes brown and wrinckles. as the graft has got bigger so has the brown skin. it doesnt seem to cause a problem, doesnt spread up the plant, and has never oozed anything. i have a couple of other graft of different variety that are just as old that dont have this problem. the oldest one is brown and wrinckly on the base but it is hard and dry. not soft.

should i just continue to ignore it?

As far as I understand this is the normal function of the cactus.

The tough dead wrinkly flesh around the 'neck' of the plant saves it from water buildup that would occur naturally once the plant is mature and has several pups.
