Google skin clinics near ur area..if u are from south africa like me u can go to Diva Slimming Aesthetics in Sunninghill, they do removal of steetchmarks. Well stretchmarks wont completely go away but atleast they can fade after a few treatments. Bio oil and other stretchmark creams alone, wont help with severe stretchmarks u need laser treatments to get them removed. They charge R1200 for 3 sessions in 1 area for removal of stretchmarks. Bio oil and other creams will only help abit I guess…Steroid creams like epiderm, bethnovate, movate, g&g, diproson, all creams that come with tubes all contain steroids…steroids cause stretchmarks in the long run…hydroquinine products can only be used for a short while if u use hydroquinone for too long, it makes dark patches on ur forehead called ochronosis. Ladies u must google information first for anything u want to do or anything the u!
Corticosteroids have been used as drug treatment for some time. Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a complicated 36-step process that started with deoxycholic acid, which was extracted from ox bile .  The low efficiency of converting deoxycholic acid into cortisone led to a cost of US $200 per gram. Russell Marker , at Syntex , discovered a much cheaper and more convenient starting material, diosgenin from wild Mexican yams . His conversion of diosgenin into progesterone by a four-step process now known as Marker degradation was an important step in mass production of all steroidal hormones, including cortisone and chemicals used in hormonal contraception .  In 1952, . Peterson and . Murray of Upjohn developed a process that used Rhizopus mold to oxidize progesterone into a compound that was readily converted to cortisone.  The ability to cheaply synthesize large quantities of cortisone from the diosgenin in yams resulted in a rapid drop in price to US $6 per gram, falling to $ per gram by 1980. Percy Julian's research also aided progress in the field.  The exact nature of cortisone's anti-inflammatory action remained a mystery for years after, however, until the leukocyte adhesion cascade and the role of phospholipase A2 in the production of prostaglandins and leukotrienes was fully understood in the early 1980s.
