Brief Answer:
follow the advises, and see how it stays..

Detailed Answer:
Hi XXXXXXX Welcome to HealthcareMagic,
I've gone through your query and understand your concerns,

First of all, please note that stretch mark is a troublesome entity and absolute cure is debatable till date (there are numerous cosmetic products and lucrative advertising to which I'd suggest not to concentrate on)...

Among the products, you can simply try any well-branded baby oil (eg. Johnson's AD baby oil twice daily for a few weeks and see how it stays)...

There's are chemical peels available i.e. Trichloroacetic acid (TCA) peels which are quite effective but it can only be applied by Expert Dermatologist's, you can go for it later on if no improvement...another effective option is Laser treatment, you can discuss it with the Dermatologists...

However, since there's also itching, please keep the area dry, wear loose-fitting clothes for a few days and observe, if at all any redness/rash/increase in the itching then it may indicate a fungal infection(for which anti-fungal medications need to be applied at first)...

Let me know if I can assist you further...

Take Care
Kind Regards
