I really do need to open up my acid bar 
. I have a PC Clear normal strength BHA travel size that you can have, JDSTER. It expires in January 2017 though so won't be of much use beyond testing it. Pretty sure it should be safe to use (it's been sealed all this time) as expiration dates on cosmetics are generally quite conservative. Just PM me if you're interested, don't want any money for it. I'm sure someone will be able to offer you a decant of the CosRx BHA (but this one is much gentler than the standard 2% BHA the different form is the equivalent of about 1% BHA Salicylic Acid based) and possibly of the Extra Strength too? ahem * cough * 
Well I sincerely doubt the sugarless sweet recipes we promised Enid will help with dieting, Raisin, but I'll be happy to share other recipes if necessary.
Describe rash to me, Raisin. Is the skin raw, agitated, inflamed? If so that's a sign to stop using it. It definitely sounds that (like so very many on here) you don't tolerate glycolic well and it's time to look at other AHA forms that are gentler. Wrt Vit C, it does exfoliate in a sense but it shouldn't be causing such a reaction, I'd contact TO and see if you can exchange it for one of their other Vit C offerings that are gentler, see the guide here.
Wrt SLS free shampoos not cleaning as effectively, this is definitely the case with some, it also depends if you're using a lot of styling products with silicones in them or the shampoo/conditioner itself has some. Usually though an SLS-free allows for longer periods between washing as the SLS isn't irritating the scalp that encourages oil production, but if it never cleans out old buildup I guess that could be the cause.
Wrt to waiting time and order of products:
I discussed it in the first or second thread already but most of these wait time procedures are derived from professional use (eg. chemical peels, etc.) where that stuff actually makes a difference, so unless a product specifically specifies a wait time assume it's useless to do so. I've tried both scenarios and found absolutely no difference.
Traditionally Vit C comes before BHA then AHA because they're pH dependent. However, since TO Vit C 23% is an anhydrous suspension (I have yet to confirm this but lack of water = no pH like an oil) isn't pH dependent, so can be placed into your routine at the serum stage instead if preferred.
I assume you've tried and disliked Bioderma, Hollin?
"Mysterious", Aurora!?! If this thread is going to devolve into perfume talk wankery I might have to leave! Appears I am moody too, must be something in the air tonight. This might end up in a lot of Sephora orders or equivalent, have already ransacked de Bijenkorf otherwise I'd head there
Just purge the social media accounts for the New Year, Enid, I doubt you'll be missing out on anything interesting. Much less aggravating too
for all of you feeling ill, sucks, especially at this time of year.
Ah yes, I remember now Salty, we were all exhausted from just reading all you do . As others have pointed out, double cleansing in the morning wholly unnecessary. Also HA and The Buffet are pretty similar in profile so use one or the other. You'll still need some sort of moisturiser in the AM though to seal in the hydrating serum, considering the Biore's high alcohol content I doubt this will really help seal that all in. I'd leave the Clarins for what it is, the N+F Dragon's blood pads are BHA so if you feel you can benefit from that (oil, blackheads, enlarged pores, etc.) then it may be worth going for that on that basis. I think TO Rosehip is a cold pressed one which is usually the preferred extraction method but with Rosehip it tends to be a CO2 extraction process (like the Pai one is) that's favoured so I don't honestly know how good the TO version is, may just be a so-so oil but it might also just be you not used to it or liking the feel of it.
Somerset, that's great to hear and welcome back!
Shrew, wrt Retinol alternatives, I didn't get on with TO Retinoid on my face all that well either, left me cloggy and needing more BHA. I've been looking into the Pestle & Morter Supertar Retinoil and since you're also looking for a new oil maybe it'll take your fancy too? You'd use it in the serum stage though, so after cleansing (and/or acid toning) and then layer whatever else over it. By no means is P50 mandatory but I do think it makes for a nicer acid than the Clarins one. You start with P50W and if people are still feeling generous on here will offer you a decant ahem * cough * and seeing that you've been using the Clarins one for a while now you may be able to go up to the full P50 quicker than most but you'd have to see how you get on with the W first (if you do end up buying it just make sure to get the smallest size - 50ml)
Also, if you like the snail poo steam cream and essence you'll love the sheet mask from them too. I just tried it and very much enjoyed it, great hydration boost.
