How can my teenage daughter deal with stretch marks?

She is distressed and I’ve reassured her that these will fade with time. Do you have any advice on how to speed up the fading process? The marks are a reddish purple, and quite noticeable.
>> Stretch marks are very common as a result of growth spurts and often appear on the thighs, hips, breasts, buttocks, and abdomen of young women as a result of physical changes and rapid growth that take place during the puberty process.
