Pain will be induced by light touches with the same pressure using a disposable needle tip on the forearm region, measured by a visual analog scale (VAS) at 10, 20, 30, and 40 minutes after application of the marker, in a sample of 20 participants.\n\n● Secondary Objective: To assess safety through the recording\n\n1. Methodology\n\n After cleansing the skin of the forearm selected by the participant (right or left), four points will be marked and the study product will be applied. Every 10 minutes, sensitivity at the application site and adjacent skin will be tested through superficial pricks performed with the same pressure in the treated area and the adjacent control area. The participant will be asked whether sensitivity is the same in both areas and will be requested to report the percentual reduction in pain at each studied point.\n2.
