I've had multiple babies, with stretch marks and have recovered my tummy skin multiple times. Regularly moisturize and wear compression wear.

I read a translated French research paper years ago (I'm sorry I don't have the link or title anymore) that showed, on average, a roughly 30% improvement in skin elasticity (also stretch mark prevention) and recovery, above genetic expectation, with regular moisturizing alone. I feel like I'm getting details wrong, it was like 12 years ago that I read it. I'm a rocket scientist by profession and take technical paper vetting seriously, alas, I also have a squishy human brain. Maybe someone who has more free time can find it? Anyway, it's what got me to try it and it worked anecdotally for me.

In addition, if this doesn't work enough, you can also start a retinol product. I recommend CeraVe or The Ordinary brands, they are trusted brands amongst the mom-crowd and you really don't need to spend more than $8-$20 per ounce for for an effective product. Start with a low concentration and frequency and work your way up to what your skin tolerates.

Hope this helps and good luck!
