What Actually Causes Stretch Marks

Most people think stretch marks are about dry skin or lack of moisture.

But here's what's really happening under the surface.

Your skin is made up of 3 layers:
Diagram of skin layers
  • The epidermis
  • The dermis
  • The hypodermis

The epidermis is the surface layer. It's your skin's bodyguard. It keeps out water, dirt, bacteria — and most skincare products too.

The dermis is the middle layer. This is where your elastic skin fibers live. They're like tiny rubber bands, letting your skin stretch and bounce back — until they're stretched too far.

The hypodermis is the bottom layer. It helps regulate temperature and protects your organs.

Most people don't realize that stretch marks actually happen deep in the skin, at the dermis layer.

When your belly grows quickly during pregnancy, the elastic fibers in the dermis snap — just like a rubber band stretched too far.

And when those fibers tear, they tear the skin from the inside, leaving red or purplish scars. Those scars are what we know as stretch marks.

Why Most Stretch Mark Products Don't Work

Here's the problem no brand wants to admit.

Most stretch mark creams are just fancy body butters.

They feel nice. They smell good. But they sit on the surface of your skin and can't get past the epidermis.

So they never reach the dermis — where stretch marks actually happen.

Do they moisturize? Sure. Do they prevent stretch marks? Not a chance.

No matter what the label says.

Why True Belly Serum Actually Works

True Belly Serum was created to solve this exact problem.

It's formulated with low molecular weight ingredients that can penetrate the surface of the skin to reach the elastic skin fibers deep in the dermis.

These active ingredients help strengthen and increase the elasticity of those skin fibers, allowing them to stretch further without snapping — reducing the risk of stretch marks.

Backed By Real Science

Clinical studies have shown that Centella Asiatica, the star ingredient in True Belly Serum, can significantly reduce the risk of getting stretch marks.

One study took a group of pregnant women who already had a history of stretch marks.

They split them into two groups.

Group 1 used a cream with Centella Asiatica.
Group 2 used a placebo cream.

The results were striking.

89% of the women who used Centella Asiatica didn't get stretch marks.

Meanwhile, nearly every woman in the placebo group did. This wasn't random — it was clinically observed.

Now, before you grab any product with centella asiatica, here's what you should know: most products that contain it use diluted extracts of only 1% to 2% Centella Asiatica, made up of 98% water and glycerin.

True Belly Serum uses a pure centella asiatica concentrate. No fluff. No filler.

What About Genetics?

Yes, genetics do play a huge role in whether or not you'll get stretch marks — because they determine how elastic your skin fibers are.

If you naturally have more elastic skin fibers that can stretch without snapping, you'll avoid getting any stretch marks.

Whereas if you have less elastic skin fibers, you'll be more prone to getting them. So if you did everything "right" last pregnancy and still got them — it was never your fault.

Now you can't change your DNA, but you can still minimize the risk of stretch marks with True Belly Serum.

Still Got a Question?

When should I start using True Belly Serum? +
We recommend starting as early as you can, ideally the moment your bump starts to show. The earlier you start supporting your skin and increasing the elasticity of your skin fibers, the better your chances of avoiding stretch marks.
Can I use this throughout my entire pregnancy? +
Yes. True Belly Serum is designed for daily use across your full pregnancy — and many moms keep using it postpartum as their skin recovers.
Does it reduce the appearance of existing stretch marks? +
True Belly Serum is formulated primarily to prevent new stretch marks by reinforcing the dermis. Many customers also notice older marks become softer and less noticeable over time, though results vary from person to person.
Can you use lotions or other products over the True Belly Serum? +
Absolutely. Apply True Belly Serum first so the active ingredients can absorb, then layer any moisturizer or oil you like on top.
Is this greasy or oily? +
No. It's a lightweight serum, not a heavy butter. It absorbs quickly without leaving a greasy film or transferring onto your clothes.
What if I have sensitive skin? +
True Belly Serum is made with clean, pregnancy-safe ingredients and is free from harsh additives. As with any new product, we suggest a small patch test first if your skin is very reactive.
What if it doesn't work for me? +
You're covered by our risk-free trial. If you're not happy, reach out and we'll make it right — no hassle.
