Light therapy is an effective treatment for uneven skin, discolorations in the skin and injury scars. There are several different treatment types, some of them involving the use of lasers and others that focus beams of broad-spectrum light onto the skin.
Photodynamic therapy is often confused with intense pulsed light treatment. The latter uses short-bursts of light energy to constrict capillaries and collagen. Photodynamic therapy involves the use of photosensitive drugs administered topically. The drugs absorb intense focused light, and the cells in the immediate vicinity are destroyed. This allows the body to generate newer, healthier cells.
Originally used to treat cancerous cells, photodynamic therapy has also been proven to be an effective cosmetic treatment for cells damaged by environmental factors. Uneven skin surface and minor wrinkling are caused by thinning skin and a loss of collagen production. We highly recommend photodynamic therapy for those concerned about small wrinkles forming around the mouth and eyes as well as those experiencing difficulty getting rid of discolorations caused by scarring or rosacea.
How the Process Works
A special drug compound is rubbed onto the affected area of skin. The drug used depends on the severity of the skin condition. Once it is applied, the client will have to wait for a set amount of time for the solution to settle into the skin and supporting tissues. The instrument used to produce the intense light beams is a special device that can be calibrated to produce only certain wavelength combinations.
The lamp is placed above the treatable area, and the light is flashed for a brief moment. The client will feel some stinging and a sensation of heat on the skin. No intense discomfort is felt, so in most cases, a topical anesthetic is not required.
What Happens Next?
The light energy is absorbed by the administered drug, and the cells in the immediate area are destroyed. This doesn’t mean that symptoms of a severe 2nd- or 3rd-degree sunburn are experienced, however. The light energy targets only specified tissues. The body responds by sending nutrients to the site. The treated area will look reddened for a short time, but normal skin tone soon reappears.
Over the next several weeks, the skin will become more even in texture because the therapy actually stimulates new skin cell growth as well as collagen production. The skin condition continues to improve over the next two or three months. The treatment can be repeated if necessary.
