The effect of a topically-applied cosmetic oil formulation on striae distensae

Abstract

Background: Stretch marks or striae distensae are tears in the dermis, above which the epidermis remains intact. Striae result from rapid expansion of the underlying tissue, e.g. during puberty, pregnancy or rapid weight gain. The prevalence of striae is high (up to 80% in most populations). Many of the successful treatment modalities for striae (laser, surgery, prescription-only medication) entail high costs, often with the involvement of private medical practitioners. The objective of the study was to investigate the effect of a topical application (Bio-Oil™) on striae in 20 healthy Caucasian women. The study was performed according to standard good clinical practice guidelines.
