Using hydroquinone with regimen

Ever since I've been on the regimen (started around mid July) I've been getting a lot of dark spots all over my face (probably around 10). AHAs are supposed to help, but I've been using 10% glycolic acid in my regimen since August, so we know that's not helping...

So I'm considering using hydroquinone in my current regimen (located in sig). Now, I know you're not supposed to use it with BP, but how about if I use it with SA. Or is that also not an option?

Age/sun spots

I've been getting a lot of age/sun spots on my face the past few months, even though I've been using SPF 30 (just started using SPF 45) almost everyday. It's starting to become a nuisance and was wondering if hydroquinone would be a good idea or if there's another alternative.

Thanks.

Using BHAs and AHAs in Regimen

I currently use both AHAs and BHA in my regimen (regimen in sig) and I was thinking that maybe it might be unnecessary to use both. Can you guys give me any input on which one I should cut out? or benefits of keeping both of them?

Thanks

BHAs more drying than AHAs?

I was just wondering if BHAs are more drying than AHAs. It seems both have similar effects in that they both chemically exfoliate the skin, but AHAs seem to be much more recommended above BHAs (at least when used with BP). Hoping to find answers why that is.

Left side of face still breaking out

I've been on the Regimen for about 2.5 months now and for most of the time my face was fine. At the moment, most of my face is flawless, except for scars and very minor, short-lived acne. However, for the past couple weeks the left side of my face has been breaking out. As far as I know, I'm not doing anything different on the left side of my face than any other part of my face.

Anybody know what's going on?
