Scar treatment usually involves the use of a surgical procedure to replace extensive scars. But recently, laser therapy has become a popular alternative to surgery. It's not difficult to understand why, laser therapy is much less invasive and requires less down time than surgery.

In recent years light therapy has become a very viable alternative to other acne scarring treatments, offering a solution to traditional scar problems and even facial blemishes. Blue light and red light are the most common light treatment therapies. Here's a closer look at both types of therapy.

Blue Light Therapy

This type of therapy has been used since the early 1980s. In fact, it was initially used to treat seasonal depression disorders. However, it has now been used to help control acne breakouts.

By using blue light therapy for acne, the person does not need to take antibiotics. This is good news for acne sufferers because our bodies become resistant to antibiotics after a certain amount of time. In fact, some doctors have began to notice that this type of therapy could also help even fine lines and fade scars.

Red Light Therapy

Red light therapy is a different story, in the 1960s, doctors in Europe noticed that certain single wavelengths had a therapeutic effect on skin tissue. More recently, cancer researchers have noticed that topical creams in conjunction with a single red frequency could kill certain types of skin cancer cells. It was later discovered that this type of light therapy could help regenerate skin tissue and improve its overall appearance.

This type of therapy can also help boost circulation and promote the production of collagen and trigger the healing process.

Scar Treatment & Light Therapy

Recently, it has been noted that instead of treating acne scars, light therapy was much better at promoting scar less healing. This makes absolute sense since untreated acne leads to acne scars. If the acne condition is treated with light therapy, then there is less of a chance that you will develop scars.

If you already have scars, it is possible that light therapy can treat them. The light helps kill acne bacteria, and stimulates the skin to produce additional collagen. As collagen is produced, scar tissue becomes more even, presenting a smoother appearance.

Light therapy can also be used in conjunction with dermal fillers to treat acne scars that are very deep. The most common filler for treating acne scars is hyaluronic acid. However, consult with your doctor to know which is the best filler for your type of skin and scars.

Possible Side Effects

You shouldn't worry much about side effects, because they are mostly temporary. Side effects include redness and flaking of the treated area. Make sure you consult with your doctor if the reactions do not subside.
