What you can realistically change
Stretch marks are scars in the dermis, formed when skin stretches faster than it can keep up with, during pregnancy, growth spurts or rapid weight change. Their age matters enormously. Fresh marks are red or purple because the damage is still inflamed and the blood supply is active. Older marks have faded to silvery white, which means the tissue has settled.
That timing decides what will help. Red and purple marks are far more responsive, and treatments applied early get meaningfully better results. Silvery marks can be softened in texture and blended in tone, but no cream erases them, and honest reviews should say so. Below you will find what each formula is realistically capable of, so you can match the product to the stage your marks are actually at.
