I have tried Mederma skin care cream one year ago . It claims to lighten the marks of stretch marks , burn marks , injury marks , surgury marks , pimple marks and almost all old and new scar . In its package its written to use it almost 3 months to see the results . I have a mark on my left hand of stitches that I got two years ago because of an injury . I bought it at a price of 367/- for a small tube and applied it almost 4 months regularly . Each day in a hope to get reduced marks but it totally disappointed me . I did not see any reduction in marks and I wasted money on buying two tubes of it . So I recommend not to buy this product for stitches marks .
