Exorex® Lotion (coal tar solution 5% v/w cutaneous emulsion) is the most important step in treating and managing psoriasis as it contains the active coal tar ingredient for the treatment of mild to moderate psoriasis. Apply Exorex® Lotion 2 or 3 times a day to those areas of the body affected by psoriasis. Do not be concerned if some of the lotions comes into contact with surrounding areas of unaffected skin. It is suitable for any age and can be diluted to suit individual requirements.
