Why Belly Oil Alone Doesn't Work

Stretch marks form deep in your skin.
They happen when collagen tears in the dermis, the middle layer. That's why they're permanent. [1]

Oil never gets there.
In studies, oils like almond and olive didn't prevent marks. [2] They soften the surface, but marks form deeper, where oil doesn't reach.

That's why we made two steps.
The serum penetrates, feeding collagen and hydration into the layer where marks begin. [3] The oil seals it in so it doesn't evaporate off. Serum alone evaporates. Oil alone can't penetrate. Together, they cover every layer.

Genetics isn't the whole story.
Family history raises your risk. It doesn't cancel the benefit of supporting your skin where marks form. [4] That's the part you control, predisposed or not.

Bonus: it stops the itch too.
Pregnancy itch comes from stretching skin and water escaping through a strained barrier. [5] That's exactly where the serum hydrates and the oil seals. Surface products only mask it.
