Paraffin oil can stop the evaporation of water from the skin and is used as an ingredient in skin care products or make-up remover oils. Paraffin oil is also used as a lubricant in specialist anorectal examinations, for example, when doing anal fingering, or anoscopy, paraffin oil is used to lubricate the anus to reduce the friction between the fingers or anoscope and the anus and to reduce the patient’s discomfort.
