Old white marks on thighs that won't fade
You have pale lines on your thighs that have been there for years. They do not tan with the rest of your skin. They stay light, flat, and easy to spot.
These are old stretch marks. Skin can tear under the surface when it stretches fast. That happens with growth spurts, weight change, pregnancy, or new muscle.
Fresh marks look pink, red, or purple. After months or years, they turn white or silver. Doctors call this pale stage striae alba, which just means mature stretch marks.
When to see someone
See a doctor if wide purple marks keep showing up without weight change. Go too if you bruise easily, feel weak, or your face looks rounder. Have any mark checked that itches, bleeds, hardens, or changes color.
Below are remedies people use for stretch marks, drawn from our reviewed list. Each one carries a grade that shows how much good evidence stands behind it. A low grade means the proof is thin, not that the idea is bad.
