You are right to be curious about how light can help treat a skin disease. The answer lies in the fact that molecules are affected by light energy. A molecule can transform into another molecule when it absorbs energy. Normally, enzymes facilitate these transformations in the body.
Psoriasis, for example, is associated with a deficiency or malfunction of specific enzymes. Light, at a specific wavelength and energy level, can mimic the function of these enzymes, thereby alleviating the symptoms of psoriasis or other conditions.
The science of how light affects the body is called phototherapy. The science of how light affects molecules is called photochemistry.
This interplay between light and biological systems has opened doors to innovative treatments for various skin conditions and other medical applications.
