If you are looking for some to do some pre party skin prep, I really recommend you try out the charcoal mask by Origins. I use this any time my skin needs a hug. It cleanses deep down into my pores getting rid of all the nasties and impurities. Note though, this is really quite heavy and you only need to do the troublesome areas. For instance, I find my t-zone a bit naughty so I will slap this stuff on there, leaving it to dry for ten minutes. Rinse off with warm water and follow with moisturising.
Never, I repeat NEVER, use this the week of your special occasion - always use this a fortnight before as this can bring out the blemishes during the clearing process.
I'm currently on the look out for a facial exfoliator for sensitive skin so if you have any recommendations for me please let me know in the comment section below.
