Allicin and Probiotics: Double-edged sword for the management of Striae distensae

Striae distensae (SD), commonly known as Stretch marks or striae, are one of the most common benign dermal lesions frequently seen in females that often cause a significant physical and psychological impact. A number of treatment modalities ranging from topicals to invasive approaches are commercially available, however, none of the available options is capable of complete eradication of SD. As effectiveness of most of the available topical formulations for SD is attributed to the combined effects of their antioxidant, anti-inflammatory and proliferative effects, allicin and probiotic based topical formulations are hypothesized to be effective in treatment and prevention of SD. Both allicin and probiotics are able to reduce the inflammatory response via suppression of transcription factor i.e., nuclear factor (NF)-κB, and pro-inflammatory cytokines and chemokines levels. Moreover, the antioxidant effect of allicin and probiotics is considered to decrease the reactive oxygen species induced fragmentation of collagen. Also, the effects of allicin on the collagen and elastin tissue as well as beneficial effects of probiotics and their metabolites on skin elasticity and skin hydration are expected to provide multiple target approach for the management of SD. Altogether, a combination formulation containing both allicin and probiotics is considered to be novel approach for the prevention and management of SD.
