Ok the amphora one contains Alcohol Den. (quite common in a simple 'natural' formulations like that) so probably not ideal with dehydrated skin.
The posh brats contains HA but not specified which type, so probably not ideal for Enid.
I've had an extensive look at the Olay moisturisers (will look at the rest another time) and sort of get why it doesn't get the all round love. It promises a lot it will never deliver, had quite a chuckle over the poor woman in a Boots review saying it did nothing for her wrinkles as there's simply nothing there to achieve this. They are sort of the poster child for everything that is wrong about misleading beauty PR. The formulations also feel a little old school, nothing wrong with it at all but to the modern paraben and everything else avoiding public they'd get a few alarm bells ringing. Mineral oil derivatives, parabens, silicones, fragrance are in almost all products. Also aluminium starch octenylsuccinate which I know sends many people running in fear (unwarranted) at the mere mention of aluminium. They do seem to have their eyes on the ball in terms of ingredients worth including in formulations, a lot of the buzz ingredients of today long established in their product line, which I think speaks positively. A final note on the brand, it's part of P&G which I tend to have some issues with wrt animal testing, social responsibility, etc. and why I personally won't knowingly buy from them. Being part of P&G, however, explains much of their advanced use of these ingredients and they are by no means a poor innovator in this field.
My other issues with them is this, they clearly have a day and night deal. Day cream all have SPF so you'll need a separate night cream whether you want it or not. Without trialling I'd never know if the night cream is too rich for day wear with a separate SPF but since they don't allude to skin types at all I assume if you're anything above dry you'd need two moisturisers which in my mind feels a bit of a rip off.
On the whole the Regenerist line feels overpriced compared to the rest of their products (I know it gets discounted a lot but I have to go by suggested RRP). I can't really see the cause of the inflated price of £15-20 on basis of the ingredients alone. Mostly the addition of Matrixyl and little else.
If I'd pick a day cream it would be the Olay Anti-Wrinkle Sensitive Skin Day Cream with SPF15 as it has a few non HA hydrators and a promise of high % Niacinamide in a paired back fragrance free formula (some ingredients are not that suitable to sensitive skin though) but I would probably look at LRP Toleriane instead (don't know how these compare price wise in the UK though, LRP is v. affordable here). I considered the Olay Total Effects Sensitive that has a few more beneficial ingredients but also potentially a lot of clogging ones.
The only thing that did genuinely look interesting from the Regenerist line is the Wrinkle Relaxing Complex which has the suspected high % Niacinamide, Vit E, Green Tea, Yeast Extract (which I assume are like Galactomyces another much loved ingredient of mine that I've neglected to mention so far, same goes for Green Tea, camellia sinensis leaf extract, Allantoin (great hydrator), Matrixyl (unfortunately not paired with its lovely sister Matrixyl3000 for better results) and Panthenol (Vit B5, another great hydrator). It has some citric acid in there most likely to keep the formulation from being too alkaline so that speaks positively. It does have fragrance in it, which bothers me as strangely enough Paula's Choice/BP who are always scathing of it disregarded it in their review, claiming it was v. minimal, however, user reviews all complain about the pungent smell so it's not a slam dunk and outside of an offer I'd find this relatively expensive for what it is. Disregarding the presence of HA momentarily, the Ordinary Matrixyl and Niacinamide with proven % actives and a simple moisturiser without fragrance just make more sense to me personally. Big tick for it being in a pump though and no SPF means it would work for day and night unlike the rest of their line. This doesn't promote itself as a moisturiser though (even though that's what is says it is) so I do wonder if it's occlusive enough for all skin types.
I know you mentioned reacting badly to HA (I do too but only if it's the low molecular weight stuff) and Salicylic but my first thought to a moisturiser you'd like with your skin type is the Malin + Goetz Vitamin E moisturiser (without SPF version). It's pricey in initial purchase but contain about 2.5x the amount of product if comparing it to the Olay Regenerist price point and it then actually works out more reasonable. You don't use much either as it's rather fluid. I liked this a lot when I was combo with dry patches. The Salicylic amount is very minimal so irritation might be limited (unless you genuinely have an aspirin intolerance) but enough to stop congestion and I never reacted to the presence of the HA in this. Ebay should have some travel sized versions available as a hotel or airline give them away, I think that may be worth a try despite the reservations with some of the ingredients.
