According to what the following says "沒有任何藥劑可以除去妊娠紋", 肚紋膏 or other cream maybe cannot really help. People can only wait "產後就會逐漸變淡變皺"
I didn't try and I don't have stretchmarks now (too early I think) and I don't know if it's true.
I am also using using "Mustela", I thought it is good but I start getting the stretch marks since 8 個月, I have lots of stretch marks all over my tummy now.
I start using Mustela last month, so far, i feel quite moisture on my tummy, no stretch mark yet. All my friends have used Mustela during and after their pregnancy, and only one of them have stretch mark after birth. I used another brand but it gave me allergic reaction.
