I'll answer you both but with the risk of this becoming an ask bo to fix my skin thread (I'm much better with the ingredients!), all I can do is advise what I would do in your place. I have no education in this other than the one I've gathered predominantly from other people that are (educated) experts on the internet but that says little of my capability of interpreting such things.

Balance Me Pure Skin Face Wash - this has citric acid in it (presumably to keep it lightly acidic) and is sulfate free. If you like it and it works for you keep going with it. I'd be hard pushed to find something comparable substantially cheaper.
Rodial Hylauronic Acid - can't figure out what this is, are they pads, a toner? or Clearasil fruit pads with salicylic acid - are these the ones that are bargainous as they're discontinued?
Vichy Aqualia thermal serum - used to be one of the few hyaluronic serums around, was bargainous then, not so much now. Either The Ordinary HA 2% + B5 or Superdrug Simply Pure Hydrating Serum if all you're using it for is dehydration.
Olay 7 effects moisturiser - nothing wrong with this, nothing amazing either but that's the way I kind of prefer moisturisers.

Super drug Naturally Radiant Hot Cloth Cleanser - Hard to economise on this one.
Nip and Fab Glycolic Acid pads - as above, Bravura London Revitalising Ginseng Toner With Glycolic Acid 5% is a possible both have similar concentrations (maybe confusing with the extreme version here) and pH. Assuming a 150ml will last you a lot longer than the pads but with offers I don't know how the economics of it would work out.
REN Omega serum /oil - I wouldn't really consider this a serum, most ingredients are Vit E related and you can definitely economise by just using Rice Bran Oil (currently liking this but should be cheaply purchased H&B, alternatively wheat germ oil. However, in conjunction with Vit E moisturiser below technically you're oversubscribing a bit on one ingredient. I think it would be best to think about what type of issue you'd like to address with a serum stage here or omit the stage altogether.
Body Shop Vit E night cream - see above about amount of Vit E. A different serum and using a Vit E rich oil here (if you like oils) would be a possibility.
On account of the greyness (I'm assuming lacklustre/dull rather than winter sallow that we all tend to get) I'd be contemplating Vit C and a Retinol but on account of the redness I'm wondering if that's sensitivity related and whether that is the wisest approach with the current offerings from The Ordinary. If it's uneven skintone related I'd consider Niacinamide, it's in the Olay but best guesses between 2-5%, ideally it's between 4-5%.

CH has her place but I agree (and think she says this herself too) that her approach is not necessarily universal. Following her does tend to breed the feeling that the next miracle worker is in easy reach but I think the high volume approach is a difficult one to find a workable routine with if you're anything but normal resilient skin with limited issues.
I've never had acne, and have done very little reading about it. As I understand it there's two approaches, the (predominantly western) which is a harsh assault on the skin eliminating every bacteria (good and bad), oils (again good and bad), etc. to the face in an attempt to eradicate it with the hope it then stays gone as the skin 'resets' and finds its balance again. This seems to work for some, others find they need even more high strength stuff under prescription while for others this method of stripping the skin leads to only more oil production putting the entire face in a continual vicious cycle of recovery, overcompensation, back to problematic.
The Asian approach seems to be one that's gentler, working with the skin to slowly restore it to a healthier stage, the pH business becomes very important here as strengthening the acid mantle (or restoring it in some cases) with low pH cleansers, acids, and ceramides gives less of a chance to the bacteria that thrive in skin with an elevated pH. I think while this appears to be the preferred approach, it won't work for everyone and a lot probably won't have the patience for it either.
As I understand it there are very few genuinely oily people, with most it is coupled with dehydration that encourages more oil production as a matter of compensation (which then continual gets stripped out on account of unwanted oils). So the banning of occlusive agents (oils, etc.) and limited care focus on hydration (lack of water in the skin) -the logic being someone is oily therefore anything to with dry seems alien and is therefore overlooked- works counter productive as you need some sort of occlusive to lock in the hydration.
If you don't want medication or see a derm about this, the only thing I can really think of worth pursuing is Blue Light Therapy, it's available in salons/derm offices but there are also a few at home devices that are highly rated (was a thread on it recently) and I suspect daily at home use might actually be preferable in this instance. It works on eliminating the bacteria exasperating the condition and not disrupting the rest of your naturally built up protection system (which harsh acne medications and products take out in the process as mentioned above).
Saying all that cystic/hormonal acne is very difficult to treat, they still don't know what causes the skin's oil glands to become hypersensitive to excess male hormones. Disregarding the skin momentarily I'd focus on the excess male hormones. There has been some recent research that spearmint (not some holistic crap, they are genuine scientific studies but there haven't been many nor are they wide studies) has a significant impact on the testosterone production. It's specifically spearmint not any old mint (I've tried it for PCOS management and do find it makes a difference but fully accept it may also be a placebo effect). I know an Asian Beauty Blogger with cystic acne who is very happy with the result since introducing it (her dermatologist was the one who suggested it), I believe it's two cups of tea a day but I think there are also some capsules out there. Just for balance, certain BC pills (Yasmin) will also aid with hormonal acne.
I don't really know how to advise where to start, I'm assuming you've gone through a lot of product hoping that each individual one was Jesus in a bottle rather than establishing a routine where the individual products play to their strength to support each other in aiding with your specific condition. Going by your unwillingness to seek out medication, the Asian approach may be more suited to you but it's not going to be producing miracles overnight and if it truly is hormonal any skincare routine will simply be maintaining and not exasperating the condition as the cause is internal and needs to be addressed somehow.
