A new article published in the International Journal of Dermatology and Venereology discussed that platelet-rich plasma (PRP) is a new treatment modality of interest in treating acne scars and alopecia, and for skin rejuvenation. 

This article presented a review of literature focusing on conditions of pigmented dermatosis and consolidate the available evidence regarding PRP usage for the practicing dermatologist. 

It was found that PRP renders significant improvement in pigmented dermatosis. This modality can be applied in a broad range of dermatological conditions and in the clinical treatment of refractory pigmented dermatoses. Limitations of PRP treatment include lack of logical and mechanical proband. Exploring the signal pathways of keratinocytes, fibroblasts, adipocytes and endothelial cells may explain its mechanism in treating diametrically opposed diseases like melasma and vitiligo.
