Hiya Frugal & mowglik, nice to see some familiar names about 
derek, you mentioned a page or two ago about the it's Skin Li Effector - I tried it too & did notice a difference although it took a while so I think you're right about it being a work horse. I was pleasantly surprised actually as it didn't get fabulous write ups when I was researching it, but figured it was worth a shot at that price. Not sure whether I'll re-purchase though or look at something else along those lines.
I really liked the Skinfood royal honey propolis & will probably repurchase that. Cleansing wise, I'll just pick and choose oils/washes that take my fancy.
Must say, I've only recently noticed the COSRX aha I bought last year getting towards 3/4 empty and the Secret Key emulsion has maybe 2-3 applications left in the bottle (probably more if I cut it to get the last out) so really good value for money. Oh and the HL Gokujyun as well, seem to have been using that forever and reckon there's maybe a couple of months left!
Unfortunately I ran out of moisturiser a long time ago, but have been using the Holika Holika sleeping pack & it works quite well underneath make up. & using up samples of other sleeping packs at night - saving the pumpkin one for last 
Sheet masks/hydrogels are the one thing I'm still not short of so am desperately trying to work through before anything reaches it's expiry date (may have been a tad over enthusiastic there!).
Make up wise I think I'd like to try another cushion & some different bb creams. I had a sample of the Lioele dolish veil (purple one) and it was realllllly nice. I expected it to be weird with it being purple but it gave a really nice base to apply the rest of my make up on & the sample did 3 days (might even have been 4!). & I love the Innisfree no sebum powder in the green pot so will definitely re buy that again.
I wouldn't mind some suggestions for oily skin to get me back in the swing of things if anyone has any? I'm open to trying out pretty much anything to see how it works
