I've been using The Ordinary 1% (in squalene) for a couple of months now. I started off once a week and now up to twice a week. I had a bit of itching, tight, dry (slightly peeling) skin at first but am over that now.
I'm going to continue upping it very gradually.
My questions is...what should I be aiming for? How often should you use it once your skin is used to it? I can't find any info on how much is optimum once you are okay with it, it all seems to be about starting out.
If you've used it a long time...how often do you use it now? Will you stick with that frequency? Has it helped with anti aging?
