I've not had no redness on my face at all,just my neck on one little area was red that's it.But I notice when I wash my face I look a little tab red not to notice!I'am using 0.05%retin-a/At night I just put my retin-a on rub in.And then I put my mequinol on top of it rub in gently!I don't put the retin-a on every night,like twice a week.Because I use kojic acid soap daily it's a exfo/skin lightening agent also,i just don't use the retin-a all the time.Nothing until now. And I am coming from a regimen with lots of acids that made me micropeel a lot (G&G with seruns, retin a, kojie san soap and KIT exfoliation). My skin was super exfoliated.
Today I used my kit on my face in the shower and when I put the lotion stung just a lit on my forehead but with this exfoliation any lotion witll do the same.
I mixed a little of the lotion MQL with palmers AHA/BHA lotion just for my legs, I think I made a 5% lotion, my legs are always covered anyway and always lighter. So I am using the 10% lotion on face, neck, arms and upper body.
I think compounding is not that easy, if was like that why people will have to study to do it? lol.
My mixes are always lit by lit because I am afraid to the stuff turning bad (I mix max 100ml total to use up fast).
Are you having some redness? stinging? how much of retin a are you mixing with the tube?
