hmm...unfortunately, I have to agree...the self-tanner will only accentuate the stretch marks and make them more visible. the tanner you are, the lighter the marks will be

i don't know of a short-term solution, but a long-term solution may be to get Retin-A, it is a cream, but you need a dr's prescription. Many people have used it for embarassing acne, scars, blemishes, and stretch marks. It could dramatically reduce their appearance, but will take 6-8 months to work.
