If i were you OP, I would go to Boots and buy a no frills unscented brand of cleanser and a moisturizer.
Cetaphil do a very nice gentle cleanser. And Cerave is also unfragranced. Both do cleansers and moisturizers.
As you are new to starting out, you do not know what you are going to react to, if you are sensitive to ingredients etc.
Once you get going with the basics, you can look to add in a serum or something to target any particular issues you are having.
I don't advise starting a whole range of new things all at once, because then if you react to something, you will not know which of them it is.
And then also get an SPF of some sort. This you might need to play around with a little, as some are more oily than others, and some leave a white cast. If there are any samples, then ask for those. I have just asked for samples of ISDN, but you have to ask. Most places won't offer if you don't ask I find. ISDN is pricy, hence why I won't buy outright before trying.
