I'm early 40s and luckily haven't had any skin problems until now so my skincare "routine" consisted of cleaning with a wipe and then more recently melting gel cleanser, and a quick lick of night cream, always something cheap & cheerful.
Really since turning 40 I notice lines and feel my skin is lacking any sort of radiance so I'd like to improve things if I can. I have bought a few things but I'm not quite sure how to use them.
I have Superdrug's Naturally Radiant Overnight Glycolic Peel. Do I just use that after cleansing and nothing else? I have Olay's Regenerist Night Elixir when do I use that? Before or after night cream? I got Strident 2% Salicylic Acid pads for my DH and am wondering if I should use them once a week as a deep treatment but again am confused about when or in what order to use them
Basically, I'm clueless about it all and feel quite dopey 
Help! (please)
