I started using Dermalogica since the age of 18, and I’m now in my late 20’s. Believe me when I say there is nothing better. When I started using it in my late teens it really helped with getting my skin really clean, because I suffered from acne and knew how important it was to have clean facial skin with out drying the skin. I would use the precleanse and then use a cleanser afterwards. As I got older and started using makeup that’s when I really started appreciating it’s wonders, Waterproof make up stands no chance against precleanse. Precleanse slays it, I’ve tried a lot of make up removers but there is nothing that I can even compare to this product. I cannot live without it.
