Light therapy has been proven to handle several problems ranging from affective disorders to pain relief but skin care is the field in which it is most popular. Light therapy is also known as photo rejuvenation and there are different methods of light therapy which can be used for different purposes. One of these methods is LED light therapy, using two colors : blue light therapy and red light therapy.

LED light therapy is used for treating two main skin conditions: acne and aging. As these conditions are not same for all individuals, there are specific treatment methods used for treating these conditions. Acne needs to be addressed first with the blue light therapy in which bacteria that cause acne is killed and thus acne begins to vanish. After that, acne is treated with the red light therapy in which red light reduces inflammation of the acne and also maintains a balance between oil and sebum production.

Red light is considered to be one of the most healing lights and that is why it is widely used as a treatment procedure for anti aging also. It increases the production of collagen, the protein that is responsible for the skin's elasticity and firmness. It also creates new capillaries, thus increasing the vascularity. With the red light therapy, more blood gets circulated through your body, flows to your tissues carrying nutrients that are helpful in repairing your skin.

Light therapy is also used for minimizing wrinkles and fine lines and is also helpful in minimizing skin discoloration and age spots. Light therapy can also be used to relieve depression, improve sleeping patterns and treat skin diseases like psoriasis and eczema. More and more people are using different methods of light therapy as they find it a safe, painless and natural way to treat their diseases and lead a rejuvenated life.

The equipment that dermatologists, spas and other skin care professionals are using are nowadays available in home use formats, as personal light therapy devices. These are affordable compared to a session you may experience at a dermatologist office. If the technology is the same, the professional equipment is of course more powerful and thus you can only get one session per week or per month depending on your condition. Personal light therapy devices are safe to be used everyday and deliver results fast, generally the first and fourth week of use.

You will find light therapy devices that only emit blue light (for acne only), red light (acne and aging) and some that emit both blue and red light (both acne and anti-aging purpose). These last ones are the most effective for acne but not necessarily the most expensive. For example, one of the latest device released, the ANSR Acne Light Therapy system is only $160, and emits both light.
