Hey xjsbellamias13 - so I dug into these products a bit more (on Sephora's REGULAR site since the stupid links kept breaking! grrr why can't companies get their websites to work better??) and I'm actually not at all impressed with the Sunday Riley product. I'm no expert in reading labels but I do my best
and from what I can tell, there's only ONE ingredient in the list that is a retinoid - Hydroxypinacolone Retinoate. I found that ingredient discussed on Paula's website as the key ingredient in a philosophy product:
http://www.paulaschoice.com/beautyp...aculous-anti-aging-retinoid-pads-and-solution
Basically what the analysis there says is, this is supposedly a retinoid that won't cause irritation, but it's not been studied enough yet. The overall tone I get from the analysis is, they're skeptical.
Almost everything else listed in the Sunday Riley Luna Oil is some form of oil or another, the main ingredient being avocado oil. These oils look mostly good to me (they're primarily antioxidants) though a fews may be irritating to some (blood orange, for example). Basically it just sounds like a very expensive combo of organic "essential oils." So I don't think this oil is all that special, particularly not given the price (!!!) though I also now doubt that it's going to cause you much problems if you try to alternate it with the AHA (the glycolic acid one).
However did you realize that you're already using a mild retinoid now, with the rosehip oil?
And that you've already got some AHA going with the salicylic acid treatments? So you ARE using similar products!
IME, glycolic acid is much more dramatic in results compared to salicylic acid so I'm not suggesting that you shouldn't bother with them. Just pointing out that you've already got some going in your regimen!
But to your
real question which is, I think, can you use an AHA (exfoliant, aka "acid peel") with a retinol (antioxidant)?
The answer to that is YES they can be used together but the reason I was so adamant in my cautions is because BOTH of them are known to cause irritation and reactions in people, and everyone's skin is different. They are both different chemicals though - AHAs are exfoliants (they dissolve away the surface layer of the skin) while retinoids are antioxidants that stimulate cell turnover. The end result is similar but the way they work on the skin is very different.
Standard advice I've seen is only use an AHA product once or twice a week; you probably don't need it every night (definitely not every night at first, you should ease into it when you start, with every other day applications at most - many people feel a tingling that can even be painful, so you'll know if you're overdoing it!!!). I'd also be careful of having a chemical exfoliator like this in addition to the La Roche Posay which I believe has a physical exfoliator and you're also doing the face scrub thing. My own opinion is that face scrubs do a lot of damage (same with foaming cleansers) but other people love them. My understanding is when you use a PHYSICAL exfoliator like those scrubs, you're putting little microtears into the skin and each time they heal they build up thicker and rougher. I avoid them, myself, but again different people have very different opinions.
Nighttime is best for AHAs; you can put retinoids on in the morning (they go nicely with a Vitamin C serum - personally Vit C is
the most important part of my skincare routine - after SPF of course!) and speaking of SPF, it's a MUST! You didn't mention any sunscreen, you HAVE TO ADD IT INTO YOUR EVERYDAY ROUTINE! Please! Minimum SPF 30. You MUST use sunscreen when using ANY retinol or AHA - it's mandatory since you're sloughing off the top layer of skin with these types of products (but you really should be using SPF every single day anyway since it's the best way to prevent wrinkles in the first place).
Wow I guess I had a lot to say about that!!
Hopefully it helped answer your questions??
Oh yeah - the sites that I use most are the product analysis pages on Paula's Choice (though I don't take everything written there as gospel), and also this great blogger from the UK, Clemmie's Big Sister
http://www.clemmiesbigsister.co.uk/ Plus lots and lots of reading an experimentation. I got turned on to the gospel of Vitamin C serum and learned so much about how to care for my skin by a book called The Skin Type Solution which is ah-maz-ing - unfortunately you really need to go through her entire self-assessment skin quiz in order to get any value from her coding system though (her website has been undergoing many renovations and I don't think the quiz is available there yet?

Anyway... I'll shut up now... If it were me, I'd return the Sunday Riley since I think it's overhyped and overpriced for what it is, but you're likely to see results with the Drunk Elephant, just go slow with it at first!!
And also: cool to you for picking mostly cruelty free brands! whether you did it intentionally or not, it's something that I respect.
