I used to apply virgin coconut oil twice a day right from the first trimester, and it kept my skin very soft. But honestly, genetic factors play a huge role too, so don't be too hard on yourself.
During my checkups at the hospital, the dermatologist there recommended a specific clinical stretch mark cream. It really helped with the elasticity, so maybe ask your hospital doctor for a good recommendation.
You can apply warm coconut oil or almond oil daily after your bath to keep the skin moisturized. It helps reduce the itching and keeps your skin soft as your belly grows.
Keep your skin hydrated with bio-oil or simple cocoa butter. I had thyroid issues so my skin was extra dry, and my doctor suggested keeping up my water intake along with moisturizers.
Haan, stretch marks toh natural hain, but tum bio-oil ya olive oil lagana shuru kar do early on. Ghar pe sab bolte hain ki khujli nahi karni chahiye skin pe, nahi toh marks pakke ho jaate hain!
Don't stress too much about marks, babe! Almost all of us get them. Just use a good moisturizer or coconut oil to keep the itching away, and wear your stripes proudly!
