Zein Obagi has been developing skin care awareness over the years and has more recently developed the ZO range, softer and less aggressive than the original Obagi. ZO recognises that the barrier function of the skin and the microflora are critical to skin health. Skin needs to adequately cleansed and exfoliated to remove dead cells, dirt, oil and pollution. The ZO range is a comprehensive package of skin care products that cleanses, exfoliates, nourishes and repairs skin and can be used as a treatment or as a preparation for a skin procedure such as a peel. ZO skin care is recommended as a complete anti-ageing skin care brand, also for pigmentation, problem, spotty, oily, sensitive and acne-prone skin.
