Most pregnancy stretch marks turn up in the third trimester, roughly from week 28, when the bump grows fastest. Some women notice them earlier, around weeks 20 to 24, and a lucky few never get them at all. The bit worth knowing is that they start forming under the skin before you can see them, so the best time to act is earlier than you'd think.
If you're studying your bump for the first faint line, here's what's actually going on, stage by stage.
First trimester (weeks 1 to 12): nothing to see yet
Your bump is barely there and stretch marks are very rare this early, because the skin isn't under much tension. This is the quiet phase, and honestly the smartest time to start a routine, since you're getting ahead of the part that matters. A daily gel and your support band ready to go is all you need. See our Day Gel and the Band Kit.
Second trimester (weeks 13 to 27): the bump arrives
Somewhere in here the bump becomes real, and so does the stretching. A minority of women start to see marks from about week 20 to 24, often on the belly, hips or breasts. If you're going to be prone, this is usually when the first signs show. Daily hydration plus support wear really matters now, so this is the point to be wearing the Band through the day.
Third trimester (weeks 28 to 40): peak stretch
This is when most stretch marks appear. The bump grows fastest, the skin is under the most tension, and the deep layer can give way faster than it rebuilds. Late pregnancy is also when the itch tends to peak, which is your skin telling you it's working hard. Keep the routine going right to the end.
After the birth: the fourth trimester
New marks can still show in the early weeks after birth as your body changes again. The upside is that fresh marks, still pink or red, are the most responsive, so it's a good window to keep hydrating and caring for the skin. Our Night Cream is built for exactly this stretch.
Why "when" matters less than "before"
Here's the catch with waiting for the first line: by the time you can see a stretch mark, it has already formed in the dermis. Prevention is about supporting the skin before that happens, not reacting after. That's the whole logic of the Band Kit. The Derma Dot™ band holds the deep layer steady as you grow, while the Day Gel and Night Cream keep the surface hydrated. Start it early, ideally around week 12, and wear it daily.
So when do they start? Usually the third trimester, sometimes the second, occasionally never. But they begin under the surface long before they show, which is exactly why getting ahead of them works better than chasing them.

FAQ
When do stretch marks usually start in pregnancy? Most appear in the third trimester, from around week 28, when the bump grows fastest. Some women see them earlier, around weeks 20 to 24.
Can you get stretch marks in the first trimester? It's uncommon. The skin isn't under much tension that early. It's the ideal time to start a prevention routine rather than the time marks usually show.
What week do stretch marks usually appear? Commonly between weeks 28 and 36, though it varies a lot from person to person and depends on genetics and how quickly the bump grows.
Can you still get stretch marks after giving birth? Yes, new marks can appear in the early postpartum weeks. The good news is they're fresh, so they respond best to hydration and care.
