Quick question about stretch marks...

I'm quite a chubby person you could say, but I wouldn't mind too much about it if I didn't have so many stretch marks.

After putting on a fair amount of weight in the past 5 years or so, my skin must have stretched quite badly to get to where I am now. I have them on my stomach, chest, back, underarms and inner thighs and they disgust me and I don't like people seeing. They're embarrassing.

After finally beginning to try to lose weight about a month ago, I noticed I have indeed lost a bit of fat all over my body but I'm concerned that my stretch marks won't disappear or fade with the weight loss. Is this true? Do they fade? Or do I have to do something alongside losing weight to lose them?

Sorry if this is obvious but thank you for your time! :D
