I come bearing good reformulation news for a change! The 2017 version of the Biore Watery Essence (and the Gel version) will be water and sweat resistant! So a much better choice year round, still wouldn't rec it for sports and there's no mention of sebum resistance but the lightweight formula is promised to be the same and it's still removable with a face wash, so promising!
But Kennington, if I turn into a blogger you'll all stop talking to me as I've become a sellout 
. In all seriousness, I am making steps to store some of this info in an easier to read form but it's a lot of work to set it up and there will be some costs involved. It's actually a bit of a challenge to see how that would pay for itself without selling my soul. I can cover the physical costs quite easily but it would be good to find a financial model that doesn't involve selling your soul to the devil or resorting to continual begging.
Fizzy, what sort of acne marks are we talking? If it's pigmentation then Vit C and Niacinamide are indeed the ones to look at but scar tissue is a different thing. Older established pigmentation takes very long to affect with Vit C an AHA can help with this too (can't remember if you're using one or not, the P50 PIGM would be a good one as it's specially formulated to tackle pigmentation issues).
The Melano CC is good for spot control right after a spot has gone but the % of Vit C is unknown, I recced that because Funny was already using it and had another backup. Aside from the high price I'd be more inclined to rec the PC's version, Resist Vitamin C Spot Treatment 25%. I couldn't find it on the UK site before when Enid asked about the Melano but they seem to sell it in 5ml now (price still extortionate) and 15ml version, though you won't need much product. If Vit C and niacinamide aren't working for you, it's worth looking into Azelaic acid, either in the PC version that combines it with BHA and Licorice Root Extract (great for established pigmentation) I recced to Funny which is formulated to tackle pigmentation while treating active breakouts or TO one which is a bit more one dimensional in comparisson.
I haven't made the recipe, I think either Grana Padano (which is practically the same and cheaper) or Pecorino Romano do exist in veggie versions. Gruyere rind might work too, no idea on the veggie status of that. I know parmesan rind is often used to up the umami flavouring in food so I guess replacing it with something else that does that (like dried porcini mushrooms) would be the best route to go down otherwise.
I had no rock bottom withdrawal symptoms 
. The two weeks weaning off sugar were no fun but after that I didn't give it much thought. Should point out I'm good at quitting things so may just have been me.
Funny, do feel free to tell me to shut up. I've been raised by a psychotherapist so tend to overanalyse. I do, however, think it is important to understand these things about ourselves to avoid repeating the same mistakes and I feel you're treating your spending issues the same as you have your skin. You've made assumptions and treated it superficially on that basis when it may require looking into on a deeper level, many of us are victims of marketing and like new things but when it comes in extreme forms there's usually something more to it.
Wrt diet, what are you eating? Speaking as someone who has had to do elimination diets for health reasons I can pretty much tell you gluten and dairy are in everything. Are you then eating a very limited diet of protein, fruit, veg, and sweets (which isn't balanced and therefore not ideal either)? Also, my advice isn't to cut anything out. It's to have yourself checked out for food allergies provided you have other symptoms that indicate a possible sensitivity to a certain food group. If you're already eating very minimal dairy I wouldn't change that, perhaps just switch to organic. I only really advocate cutting sugar because from experience it's easier to manage than low sugar to reach the advised maximum daily sugar allowance. I'm not a proponent of cutting out entire food groups without medical reasons at all, it's about finding the right balance.
I forgot to add in that I recced the EltaMD SPF since it has a high % Niacinamide in there so is a good multitasker, and also if you find little else helping your acne further down the line, it's worth looking into blue and red light therapy (the home devices are actually preferred for this due to daily use).
I love how we're all obsessed with color correcting products, Hollin. You're sporting the purple, Purple's sporting the yellow concealer, and us Sisley fanatics are slapping on the orange, and lest we forget yongnian and THE palette 
.
Speaking of BB creams, from the AB Reddit: The Dr. Jart Premium BB cream is most likely mispriced on the Boots site, it's £8 but should be about £26. Comments indicated it was quite a nice one so could be a nice bargain for those of you in the UK. Comments indicated a perfect match for NW20 and it being slightly pale and pink so possibly a NW15 could make it work too.
Purple15, I like Laura Mercier Tinted Moisturiser but it may not have enough coverage so you'd have to spot conceal. I was quite impressed witht the Urban Decay Naked One & Done foundation/TM/BB hybrid but the shade range was very limited.
Storm, I must have missed the memo that cellulite is now curable . All that product does is help ease the otherwise natural healing of those issues by fighting inflammation which would have otherwise resolved itself, albeit it slower, or in the case of things like cellulite it helps with appearance, as long as you use the product.
If it helps, can you all just start viewing all these internet brands/spiels/miracles/market pushes through social media like the old school home shopping/QVC? We all knew it was a shitty knife set but somehow there were always enough people out there to believe in the magic of slicing through frozen foods and cans and praising the magic of it before it all ended up in charity shops and landfills.
