Bio-Oil helps reduce stretch marks formation and assists the expanding skin during pregnancy and periods of rapid growth. It improves appearance and maintains the elasticity of scar tissue.

It improves the looks of scars (new and old) and hydrates dry skin to reduce itchiness and improve skin comfort.

While Mederma helps to treat scars relating to surgical operations, wounds, and cuts but does not have acceptable results in handling issues like laser wounds and burns.

Mederma advanced gel can eliminate stretch marks, Alopecia, microbial infections, etc.

Mederma and Bio-Oil are well known for reducing scars and stretch marks. But, different individuals still find either of them suitable for one purpose and ineffective for another.

Meanwhile, Mederma is effective and helps remove injury scars, stretch marks, and cuts. It is also effective when using it for microbial infections and acne scars.

From this, we can say that Mederma gel is more effective in removing and handling stretch marks and scar tissue.


Pricing is an important factor when comparing Bio-Oil vs Mederma. Bio-Oil is less expensive than Mederma, and their price difference is not much.

In general, these skincare products are very affordable. The price difference isn’t much of a strain on your budget.
