The use of gold and silver nano-particles has been confirmed and popularly used for cosmetic material ingredients, where the small Ag and Au nano-particle diameters have no toxic with human cells, especially, for facial cells, in which the nano-particle diameter range of few nanometers, for instant, the average Ag and Au's diameters are 3.63 nm and 1.33 nm respectively. In this work, three interesting nano-particles Ag, Au and Platinum (Pt) that were prepared by the Bangkok Assay Office (BAO) laboratory, in which the safety concerns are tested in terms of human dermal fibroblast cells by the BIOTEC, NSTDA in Thailand. From the obtained results, the Pt nano-particles were successfully prepared for the first time, where the sizes were ranged between 50 to 60 nm. All prepared nanoparticles were tested and the human cell safety was seen without any toxic, which leads to being useful for the medical, healthcare and cosmetic applications, which was focused on the use of platinum nano-particles for the facial cosmetic material ingredient, where there is no evidence of human cells effect, which is confirmed by the BIOTEC, National Science and Technology Development (NSTDA), Thailand. In addition, the facial gesture model is proposed for the use of facial muscle monitoring that can be observed relatively to the change in facial cells, which is useful for further developments after the treatment, which is discussed in details.
