My mum has been using this cleanser for many years and it wasn't till I had my skin assessed by a Dermalogica consultant, that she believed it was the best cleanser for my skin as well. Ever since using Essential Cleansing Solution my skin feels smooth and hydrated. It doesn't strip my skin of its natural oils and only a small amount is required to cleanse the face and neck. I haven't had any adverse reactions to this product and I will continue to use it. I always use my essential cleansing solution after using Dermalogica's Precleanse to get a deeper cleanse.
