The Secret Saviours Support Band, Day Gel and Night Cream were invented by a surgeon and a tissue engineering professor; doctors and scientists who really know their stuff. Now this is where things get interesting. They realised the skin might act like pulling across the top of a sheet of paper. Quite a lot of force can be applied with nothing happening. But when a small tear is put in the top of the sheet of paper, pulling will create a sudden rip downwards, just like a stretch mark might form as the skin on the tummy wall adjusts to the strains of a growing baby inside. The top layer of the skin, known as the epidermis, keeps everything together – but by this point, there’s no hiding the damage to the dermis underneath, the itchy red lines we know as stretch marks.
