Jessica L.
I've tried every stretch mark cream out there. They all left my skin feeling greasy and did nothing by the end of my pregnancy. This is the first one that actually absorbs properly and feels like it's working. No residue, no sticky feeling, just smooth skin. My bump stayed stretch mark free way longer than I expected. I didn't expect much — but this completely replaced every other product I was using.
What Actually Causes

What Actually Causes Stretch Marks

Most people think stretch marks are just about dry skin. But what's really happening goes much deeper than that.

Your skin has 3 layers. The epidermis is the surface — it acts as a barrier, keeping out water, dirt and most skincare products. The dermis sits beneath it, and this is where your skin's elastic fibres live. Think of them like tiny rubber bands — they allow your skin to stretch and bounce back. The hypodermis is the deepest layer, protecting your organs and regulating temperature.

Here's the part most brands won't tell you — stretch marks happen in the dermis, not on the surface. As your belly grows rapidly during pregnancy, those elastic fibres get stretched beyond their limit and snap. When they tear, they leave behind the red and purple marks we know as stretch marks.

That's why creams and butters that sit on the surface will never prevent them. They simply can't reach deep enough.

We've carefully selected each ingredient in our serum to ensure you get the most effective protection during pregnancy. These ingredients work together deep in the dermis to strengthen your skin's elastic fibres, giving you the support your growing bump deserves.

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 the chances of avoiding stretch marks.

Can I use this throughout my entire pregnancy? +

Yes. The formula is designed to be safe and supportive from early pregnancy through postpartum. Most moms continue using it after birth to help fade any marks and improve skin recovery.

Does it reduce the appearance of existing stretch marks? +

Yes, the serum can help to reduce the appearance of existing stretch marks too; especially if they are still new (reddish or purplish in appearance).

Can you use lotions or other products over the True Belly Serum? +

Yes, you can. But we recommend applying the True Belly Serum first and allowing it to absorb into the skin before applying other skincare products.

Is this greasy or oily? +

Not at all. The serum is lightweight and fast absorbing. It soaks in quickly, and leaves no residue or stickiness. You can apply it and get dressed minutes after.

What if I have sensitive skin? +

The formula is gentle, all-natural, and made with ingredients rated 1–2 on the EWG scale—safe even for sensitive skin. If you're unsure, we recommend doing a patch test with a small amount first before applying a full dropper.

What if it doesn’t work for me? +

Try it risk-free for 30 days. If you’re not satisfied for any reason, we’ll refund you. No return required. No questions asked.
