Hello. Thanks for writing to us at healthcaremagic The cream that you have been using contains a potent topical steroid i.e clobetasol propionate 0.05%. Chronic long term regular use of potent steroids can lead to side effects like skin thinning, atrophy and stretch marks. The effects and also the side effects of topical steroids are local i.e at the site of application. If you have been using this cream at these sites where you have developed stretch marks, probably they are due to this cream. However, in some individuals stretch marks can be idiopathic and are part of the growth spurt during puberty. It is not possible to completely erase stretch marks but they can be made to look better cosmetically. Tretinoin is available in a cream form and is known to stimulate collagen production and collagen re-modelling. You may try this cream; results are gradual and usually a 6 months trial period if advisable. Certain procedures like Fractional Co 2 Laser; microneedling etc can also bring reasonable cosmetic improvement by stimulating collagen production. I would suggest that you visit a dermatologist for the needful Regards
