Non comedogenic is a term used to describe products that are designed to be used by people who suffer from acne or who have congested skin. The problem with this term is that there is no industry standard or regulator that tests products against a standard. Whilst the beauty and cosmetics industry uses this term widely to mean safe for people with acne, oily skin and congestion, it does not guarantee the product. We have extensive experience with formulating skin friendly products and our ZENii Doctors work closely with our formulators to create products that are suitable for oily skin types. We will always list products on the product description guide that are suitable for people with problem/oily skin to use.
