Due to abnormal metabolism of the epidermal cells at the opening of the hair follicle, aging keratinocytes cannot be shed smoothly. Coupled with the influence of male hormones, the sebaceous glands secrete too much oil, the pores are blocked, and acne bacteria multiply. They decompose sebum in hair follicles and make fatty acids, and these chemically react with substances on the skin to produce acne.
In order to solve the acne skin, a key step is to kill the acne bacterium.
To kill the acne bacterium, we can use the technology of PDT LED therapy.
LED Skin Rejuvenation is the interaction of light, delvered through Light Emiting Diodes (LEDs), to activate cell receptors causing them to produce collagen or multiply.
One of the original applic ations for LEDS was PhotoDynamic Therapy (PDT) using photo-activated creams for the treatment of actinic keratosis and pre cancerous lesions.
