Annoyingly, this time, taking Tetralysal had only a very minor affect on my skin. Whereas before my chin completely cleared up, during this course I still regularly got zits there.
This made me think that maybe it was the Isotrex, rather than the Tetralysal, that had in fact been the reason for my improved skin a few months previously.
I still had some Isotrex leftover so started applying this again (despite its having been open for far longer than it should have been…) Stupidly, I forgot just how harsh this gel is and how sparingly you need to use it at first. I put too much on too quickly and within a few days I had a massive, cystic spot on my chin which, thanks to the combination of size and bright red colouring, looked (and felt) like an Icelandic volcano threatening to erupt.
So I haven’t touched Isotrex since then!
Determined as always, I continued with the Tetralysal course, feeling that it was at least keeping my skin at bay, but still not really clearing it.
