Abstract: In this study, hyaluronic and glycolic acids were adsorbed on Tutmaç clay. Clay brought from the village of Tutmaç in Guzelsu town of Gurpinar district in Van. The clay we obtained in the form of large particles was first sieved with a pore size of 0.038 mm (400 mesh). This ground clay was heated in an oven at 100 °C for 24 hours and stored in a desiccator. The clay sample, that is, 0.2 gr clay, was weighed 10 times and adsorbed for 10 minutes at room temperature with 1,2,3,4.5 ml of concentrated hyaluronic acid and glycolic acid for each 0.2 gr clay. The same operations were carried out for heat-treated clay. When the adsorption process came to equilibrium, the samples were filtered on filter paper and then washed with ionized water. The solid part was dried and the Differential Thermal Analysis (DTA), Thermogravimetric Analysis (TGA) and Scanning Electron Microscope (SEM) analyzes of these samples were performed, and the results were obtained by interpreting the analyzes in the central laboratory. In this study, studies were carried out on pure clay and clay treated with acids. As a result of the processes and thermal changes, it was observed that the amount of hyaluronic acid adsorbing was higher in the untreated clay, and it was concluded that these clay minerals can be used as a skin mask when suitable conditions are met. At the same time, it was concluded that the pore structure of the clay was deteriorated and it moved towards an irregular shape with the heat treatment of pure clay.
