I use to have problem skin and was on medication for it so I have been threw MANY facial cleanses. Dermalogica Special Cleansing Gel is worth every penny! I purchase the salon size of 500mls and it lasts me the entire year if not a little more. All that is needed is a drop and has the most divine silky feeling when applied to the skin. I have never had an irritation or break out while using this cleanser. I rave about this product and would definitely recommend it especially to those who have sensitive skin.
