I shouldn't really be in the business of doling out detailed skincare advice unless it pertains to hyper-sensitive, papule-prone, easily flushed, sometimes-dull-sometimes-oily fair skin with warm undertones and mild rosacea. That would be the only complexion of which I have a profound knowledge as I've been plagued by it from the age of 14.
There are others with a far deeper and more clinical expertise of skin and its myriad issues than me. Sure, yes, I'm referring to Dermatologists but there are some non-MD types who I've found give out pretty thorough advice too. One such person is a blogger I've visited time and again (going on 4 to 5 years) for good, no-nonsense advice on skincare and skin conditions named Caroline formerly of Beauty Mouth (now just Caroline Hirons). She does a regular clinic where you can ask a question and she'll answer it. Sounds simple, but you'd be surprised at how hard it is to find good, correct information on your skin and skincare on the internet or even from your Derm. I wandered over to her site yesterday and it reminded me what a good idea it is (entirely relying on, of course, who is doling out the advice... in this case, someone who has been in beauty a long time).
For those in the US, many of the products she talks about are sadly unavailable here but the advice is always good, above and beyond the product recs. It's worth trawling through the old clinics as well or the Cheat Sheets (sidebar, scroll down) too for info and advice.
