We discussed that on the first thread too Somerset, I think I was charging £250 there's definitely a gap for it in the market, especially something online based. I think where I'm located (in the Netherlands) there'd be less of a demand for it (in a physical location), at least in my immediate circle people wouldn't pay for it despite earning plenty but probably would if you tied it in with makeup consultations which I'd be useless at.
I don't think Aurora mentioned SMA just a SPA that I think her phone turned into capitals
. It tends to be spas that exclusively sell the P50 lotions in the UK.
Acronyms used on here a bit:
TO - The Ordinary
SS - sunscreen
OCM - Oil Cleansing Method (a bit of a hollistic/traditional approach to oil cleansing, just using pure oils to clean your face with but lacks an emulsifier so tougher to cleanse off your face completely, not ideal for everyone but beneficial for some)
AHA - Alpha Hydroxy Acids - help weaken the bonds on the outer layer of the skin and encourage cell turnover to reveal brighter/newer skin
BHA- Beta Hydroxy Acids - oil soluble so works on a deeper level of the skin, clearing out pores thus helping halt their oil production and help reduce the appearance of pores.
SPF- another sunscreen acronym
CB- Cleansing Balm
DECIEM- parent company of TO, NIOD, Hylamide, etc. not really an acronym but some people think it is.
LG- Liquid gold not the electronics manufacturer 
There's probably more... ask and I'll keep a list of them so they can be put in the next OP as we look to be heading towards a new thread again. Aurora, what ridiculous non title shall we come up with next
?
wilting remind me of your profile again, I'm not crazy enough to keep files on you lot yet. I know those two are super functional but what would you like from a cleanser?
And will someone offer Somerset a P50W decant already? I know you're all a lovely generous lot and some bought way too much of it anyhow so could spare to donate some
