This little "Meet Dermalogica" kit was the beginning of my great skin! I'm 66, so yes, I've tried products from drug store to high end, from many countries & every price range. After receiving some samples from a local salon and having good results, still I would only commit to travel sizes (knowing my sensitive, acne-prone skin can have a delayed reaction). Wow--clear, bright skin. Simple routine. I'm slowly working my way through the product line--even trying some that aren't recommended for my skin (with good results!). I'm still old, but minus the zits & rosacea-type bumps. Thanks Dermalogica for offering small-size kits with core products at an affordable price! My skin thanks you too!
