Example 1

Photon skin tendering is a typical representative of noninvasive and minimally invasive cosmetology, but the action mechanism of photon skin tendering is still not quite clear in recent years, and for further application of photon skin tendering, the action mechanism of photon skin tendering is studied in the research of the national institute of science (third army medical university, deng Xiangdong, research on clinical effectiveness observation and partial mechanism of photon skin tendering), by carrying out systematic clinical observation on photon skin tendering and carrying out partial animal experiments, so as to better guide clinical practice.

The study uses incoherent intense pulsed light (intensive pulse light, IPL) to treat spots, fine wrinkles, capillaries, and to react to erythema and to proliferate skin dermal collagen and to irradiate times and energy, as well as to change the beta 1 integrin expression of vascular endothelial cells, hair follicle cells, epidermal cells.

						Epidermal cells	-	++	+++	+	±

Based on clinical observation, the study carries out partial animal experiments, and observes the effective intensity, the action maintenance time and the expression change of tissue beta 1 integrin of IPL to obtain the following conclusion:

1. IPL requires different energies for treatment of different lesions. Lesions at the same tissue level require the highest spot energy to treat the stain, secondary to fine wrinkles, and lowest telangiectasia.

2. The threshold intensity of IPL induced collagen proliferation is close to that of IPL induced erythema reaction, so erythema reaction can be used as a reference standard for photon skin rejuvenation procedures.

3. Under the effective action of IPL, the dermis may develop new collagen formation, sometimes accompanied by thickening of the epidermis layer. And the photon skin tendering treatment effect can be maintained for more than 3 months.

4. When the IPL irradiates the skin, the parts such as epidermis, hair follicle, blood vessel and the like have obvious photo-thermal effect due to the light absorption characteristic and the characteristic of a space structure.

5. The effective stimulation of IPL can obviously increase the expression of beta 1 integrin of vascular endothelial cells, hair follicle cells and epidermal cells, and suggest that the synthesis and secretion of bioactive factors by the cells are enhanced, and the synthesis of collagen by nearby fibroblasts is promoted.
