Since waxing stings the skin, many waxers use pain-reducing gels (usually 4% lidocaine) that are specially formulated to penetrate intact skin. The pain-reducing gels are applied 30-60 minutes before waxing. The special lidocaine provides an effective numbing action during the waxing procedure. The gel is formulated so that it does not interfere with the waxing procedure or reduce the adhesion of the wax to the hair.
A moderately thick layer of lidocaine gel works best (about 0.4 grams of gel per 10 square centimeters of skin). Usually, the skin above the upper lip or eyebrow area will be sufficiently numb to perform waxing without discomfort after 30 minutes. Other areas, such as the legs or bikini areas may take longer, 45-60 minutes. The gel is often covered with occlusive plastic wraps, such as Saran Wrap, Cellophane Film, Tegaderm or Flexi-film, which promote the penetration of the anesthetic numbing agent into the skin. This wrapping is especially useful for skin areas with less skin blood supply like the legs. The longer the application time, the deeper and more complete the degree of analgesia.
The lidocaine gels should not be applied inside the eyes and contact with the eyes should be strongly avoided. If contact with the eyes does occur, flush the eyes with saline solution or with water. Before waxing, it is recommended to wipe the area with a clean, moist towelette.
A somewhat different pain-reducing gel that is used by many waxing salons is EMLA® cream. It contains a combination of 2.5% lidocaine and 2.5% prilocaine. It is a prescription product from Astra Pharmaceuticals costing about $40 per 1 oz. jar.
