PDT LIGHT THERAPY
Photodynamic therapy (PDT) is a form of phototherapy using nontoxic light-sensitive compounds.
To stimulate cells to produce more porphyrins, a substrate called 5-aminolevulinic acid (ALA), which is a precursor to the porphyrins, is applied to the skin. The cells that take up the ALA are generally those which are more active, for example, sebaceous glands, bacteria that cause acne (p.acnes), Therefore, PDT can help reduce acne, psoriatic plaques, solar or actinic keratosis. It can also reduce superficial basal cell (skin lesions caused by sun-exposure/damage) by targeting the cells that cause these problems.
PDT LIGHT THERAPY can be used on any part of the face or body, for example, for back acne or for solar on the hands.
There is some evidence to suggest that photodynamic therapy also enhances the usual photo-rejuvenating effect on the skin, such as reducing pigmentation, fixing broken capillaries, and improving skin texture.
In summary, ALA selectively targets the cells that cause acne and then is activated by an LED light, which selectively destroys these cells.
