This new technique is called photodynamic therapy and it uses a special chemical solution applied to the face. This solution makes the damaged cells sensitive to light. After applying the lotion the patient is brought under a special blue light. The combined use of the chemical and the blue light kills the precancerous cells and can also attack cells below the skin's surface.

Researchers say that this new technique is capable of clearing up severe acne and can also stop certain types of skin cancer in the earliest stages.
