Worth it!
I started using secret saviours during the second trimester of my first pregnancy, using the full briefs and morning and night cream. I wore the briefs most days, until around week 37 when it no longer fitted me.
Amazingly, I did not get a single stretch mark from the pregnancy. This was a surprise to me since I have significant stretch marks on my thighs and breasts from growth in puberty, and therefore assumed I was genetically predisposed to stretch marks.
The support of the band/briefs was also a large part of what convinced me to wear it, as it was helpful in holding up the bump, and towards the end of the pregnancy it also felt as though it helped hold my skin together.
I would definitely recommend this product. It was an effort washing the briefs daily and remembering to put on the cream, but in the end I am so happy I did it. Keep in mind you will need the cream for it to function - especially the morning cream which helps keep the band in place. I ran out of cream during the pregnancy, so it may be an idea to order extra cream.
