mm.. I've used the MAC skincare range- it's ok. I mean... it worked well enough, but it wasn't the BEST. My skin is quite sensitive- oily in summer, dry in winter, particularly around the nose.
I know this one is hard to get hold of, and isn't exactly a department store brand, but my skin completely freaked out recently- I tried cleansing with cetaphil (no luck...) the MAC cremewash, which is ok, but a tad on the drying side and MAY not have removed absolutely everything... the Shu oil cleanser... etc. and the same with cycling through moisturisers... but I found that only Olos worked for me.
Olos Natura is an italian salon brand. I know that it is available in Canada through beauty salons... and unfortunately not available over here at all. There isn't much info on the net about it, but they do have a range for younger skin types (I just turned 22) called the Fitomarina range, which all contain sea water or something along those lines.
I know there are little sample packets- that's what I'm using atm, so see if you can get hold of them. I'm dreading the day when I run out.. because this was the only thing that kept my nose from peeling and flaking like nobody's business, AND kept me from being oily. It's a gel moisturiser.
