I was put onto Dermalogica by a friend who works in the beauty industry. She explained that (in my mid-20s) I should try not to use cleansers that are aimed at teenagers - I'm past the awkward acne phase of 3rd form and my skin needs something different now.
Dermalogica is an investment, I pay close to $100 for a bottle, but it lasts up to 12 months and I'll never look back. To make sure I don't get too trigger happy with the pump (I tended to give myself too much simply because I was pushing down too hard) I use a separate, smaller bottle which helps me manage how much I'm using.
You only need a small amount, the size of a pea, to create a really good lather. Of course if you're taking off makeup you might need to go for a second round.
It doesn't make my skin feel dry or tight - just fresh and clean.
This is a lovely cleanser, soft on the skin and leaves your skin feeling super smooth. However, I find that cetaphil will give you the same results for quarter of the price.
In my opinion it is definitely not worth the price you pay for it and it didn't help with my acne prone skin either, sometimes the expensive stuff is just as good as the products you can buy at your local supermarket
Tips: A little goes a long way, it comes out quite fast so be careful
