i swear by dermalogica too, their website is great, they have good money off offers and they send samples too.
i cleanse, tone, serum, eye cream and moisterise every day, and i cleanse, tone and night cream every night.
i also exfoliate twice a week and face mask once a week
it sounds a lot, but i LOVE to do it, it's enjoyable and a real pamper/treat and also i hope it'll pay off when im older (i'm nearly 32)
don't forget your neck mind you, and with your neck, always brush up!
enjoy!
