Laser treatment for acne is a very advanced yet effective procedure. There are typically two types of laser treatment. One is called the Diode laser treatment, using a 1450-nm diode laser. Studies have found that the diode laser effectively treats inflammatory acne. For this treatment, only a topical anesthetic is needed. Side effects may involve temporary redness and swelling.
The other treatment is called the pulsed dye laser (PDL), which is used to treat more severe cases of acne. The PDL is slightly painful; patients feel some stinging such as a rubber band snapping on skin. After the treatment, there might be some bruising that appears in the treated area and could last up to 2 weeks.
In laser treatments, a beam of light is used across the skin and gets absorbed by the red pigment of the skin. The treatment aims at closing the pores to reduce sebum (oil) production and lessens acne. Although laser treatment is known to be effective, there have been reports that some acne lesions tend to reappear after a while, depending on the individual skin type and severity of acne.
How do you know if you need laser treatment? It all depends on the type of acne you are suffering from. So, please consult your doctor and he/she will be able to help diagnose your condition and types of treatment.
