The internet is awash with sources for buying Retinol A but, as with everything else, quality is bound to vary.
I have bought from a few sources and the current batch of tretinoin (.05% cream) has no side effects.... but I'm starting to wonder if that's because it's having no effects either.
I've started alternating with Tazarotene 0.05% gel which my wife got on presciption from a UK chemist and that definitely causes minor redness/dryness from time to time, but I never have anything noticeable from the tretinoin.
So I'd be very interested to hear where people get there Retinols from so I can compare, in particular where people have noticed the typical side effects initially, indicating they are probably genuine. If this is seen as something mods want to put in drug supplier discussions then so be it but this seems the most relevant section from a target audience perspective.
If you feel compelled to say "go see a doctor and get a proper prescription, stating you are "clinically vain"" then please save you well-meaning breath.
Over to you.
