right so, i was asking specktra this about 5 years ago, unfortunately to no avail i did not find my holy grail through suggestions but i may as well share my two cents
your skin is not the same as others, what works for some may not work fror you, what i like,you may not..
estee lauder skin recovery complex.
one word uh-may-zing! its an almost instantly absorbed serum, this stuff has changed my life. it helps my skin no end, however... you still need a good moisturiser, this just helps repair ur skin, and helps restore it so it isnt so dry, damaged and dehydrated.. you still need a moisturiser too. this serum is my MUST HAVE, that said, it is pricey but so worth it, its like a vitamin shot for your face
this has a zingy smell, so i'm not sure about ur skin type? maybe ask at a counter for a sample??
for moisturisers, i can suggest a few,
johnnsons face cream for dry/sensitive skin (of the cheap ones this was the best)
avene (the french brand) rich compensating cream (my fav) http://www.avene.co.uk/Rich-Compensating-Cream-Range i believe these are okay for sensitive skin?
nivea natural beauty face cream for dry/sensitive
i have used mac comeplete comfort, it was okay, it did its job, with the serum it would be a good combo
another must have for dry skin elizabeth arden 8 hour cream... this stuff stinks, i hate the smell, but when u have a dry patch that just wont shift, there is no other, it has a texture like vaseline, but put it on overnight and by morning, flakes be gone
also, investing in a clarisonic helped me ban flakes for good
