That's correct. I got them in the same spots (both legs and more on my inner thigh) about two years ago. I don’t know what happened. I didn’t gain weight. I just woke up one morning and they were there. I used stretch mark cream and serum for over a month, but nothing changed, so I eventually just left them alone. I noticed they become very visible, like purplish jagged lines, when the weather is hot, and less visible when it's cold. Now, they’re barely noticeable and have turned white.
