The clinical study aims to measure the changes in the stratum corneum on older healthy participants due to the application of a wet pad on the forearm. Participants are subject to baseline measures of TransEpidermalWaterLoss (TEWL), skin hydration (SH), pH and water profile (raman spectroscopy). Dry or wet pads are then added to the skin and worn for two hours. After a recovery period, the SkinSurfaceWaterLoss (SSWL) and skin hydration and water profile is measured. The study is conducted over a single visit. Pads on the arms consist of incontinence product cutouts and are loaded to 50% or 100% capacity. The endpoints are the changes in stratum corneum as measured by the instruments during the visit.

The test pads is to both forearms of the participants. Participants will be blinded to the test pad type. In total 4 pads are applied per participant. The test pads are either Dry (control), 50% or at 100% capacity. Dry and 50% pads are applied once, 100% capacity twice. This to allow one pad for recovery measurement and one for water profile measurement. Pad location will be randomized.
