Abstract
The effectiveness of Palmarosa, Neroli and Jasmin blending oil on dry skin of rat induced by kitchen detergent are investigated. The experimental groups were divided the control group, group treated with surfactant, group treated with Palmarosa and Neroli, and group with Palmarosa, Neroli and Jasmin. Observation of epidermis and the alteration of mast cell were performed with photomicroscope. According to the epidermis morphological changes analysis, the A3 group treated with Palmarosa, Neroli and Jasmin blending oil was appeared the most similar with the control group, and the A2 group applied with Palmarosa and Neroli blending oil was sequently displayed similar characteristics. The collagen layer's breakaway resulting from Palmarosa essential oil, the collagen layer's restoration resulting from Neroli essential oil, the collagen layer's retention hyperkeratosis resulting from Jasmin essential oil were observed in the structure of the epidermal layer. In photomicrosope observation of mast cell to examine the inflammatory reactions, the increase in size and number of mast cell were showed in A1 group treated with surfactant compared to the control group. The number of mast cells definitely decreased in groups which were treated with Palmarosa, Neroli and Jasmin blending oil.
