LOW LEVEL LASER THERAPY
Can Laser Really Help Acne?
Br J Dermatol. 2009 Feb 23
This study identified 25 trials (694 patients), 13 of light therapy and 12 of light therapy plus light-activated topical cream (photodynamic therapy, PDT). Overall, the trials of blue light, blue-red light and infrared radiation were more successful, particularly those using multiple treatments. Red-blue light was more effective than topical 5% benzoyl peroxide cream in the short term. Most trials of PDT showed some benefit, which was greater with multiple treatments, and better for noninflammatory acne lesions. However, the improvements in inflammatory acne lesions were not better than with topical 1% adapalene gel, and the side-effects of therapy were unacceptable to many participants. This study confirmed that some forms of light therapy were of short-term benefit.
Laser and Skin Disease
Photomed Laser Surg. 2010 Aug 25
Many LLLT practitioners ask about treating skin diseases with a laser. Here is an interesting study that confirms previous studies showing anecdotal evidence that patients with Oral Lichen Planus may benefit from LLLT.
To date, the most commonly used and useful agents for the treatment of Oral Lichen Planus (OLP) are topical corticosteroids. The investigators studied a prospective cohort of 13 patients affected by OLP, who received biostimulation.
This study suggests that LLLT could be a possible treatment for patients with unresponsive OLP. These results are a step forward for enhanced management of this quite common condition; however, it would be interesting to see if the results would be the same with a greater number of patients or in a different clinical setting.
Skin Disease: Laser is As Good As Cortisone
Photomed Laser Surg 2011 Jan 8
Thirty patients with oral lichen planus, a serious chronic skin disorder, were randomly allocated into two groups. The experimental group consisted of patients treated with low-level laser therapy (LLLT). This study demonstrated that LLLT was as effective as topical steroids, but without any adverse effects! They suggested that LLLT should be considered as an alternative treatment for lichen planus in the future.
