Intervention Model

PARALLEL

Induction period (3 weeks): the experimental and control product will be applied through a patch test on the participants' back for 3 consecutive weeks, with 3 weekly applications, with the first week being the primary irritation phase and the two consecutive weeks being the irritation phase. accumulated irritation. Rest period (10 to 15 days): corresponds to the rest period, when participants will remain without any contact test applied to their back, which will follow the induction period, where there will be no application of the experimental and control product. Challenge period (3 days): the experimental and control product will be applied to the participants' back, in a naïve area. Products will be removed after 48 hours, with readings taking place after removal and approximately 24 hours after removal. This period corresponds to the sensitization phase.
