With my PCOS history, my skin was already prone to hormonal issues. I tried using cocoa butter, but honestly, some marks still appeared and that is completely okay. Don't stress too much about them, your body is doing something beautiful.
With my busy work schedule, I didn't have time for fancy 10-step routines. I just kept a tub of basic coconut oil on my office desk and bedside table and rubbed it on my belly quickly twice a day. It worked well enough for me.
I don't know about preventing them completely, but keeping skin hydrated from inside is key! I drank lots of coconut water and fresh juices to stay hydrated, plus applying some olive oil. At least it gave me an excuse to eat more juicy fruits!
Haan na, everyone keeps giving different advice for this. Honestly, some marks will come because the belly stretches so much, but applying simple ghee or almond oil keeps the itching away. It's very normal, tension mat lo.
You don't need to buy expensive high-end creams for this. Just use simple virgin coconut oil or even home-made ghee after your bath while the skin is still damp. It keeps the skin soft and is very pocket-friendly.
According to my pregnancy tracker app, stretch marks are mostly genetic, but keeping the skin hydrated helps a lot. I used to log my daily water intake and applied bio-oil twice a day from the first trimester itself.
