Just try diff lotions for dry skin
The only lotion that has helped me out a lot with my itching (but for me It's mostly on my lower stomach) Is this one Dermasil Labs Lotion. It's for severe dry skin but It defiantly locks In the moisture and stays on all day. It has skin lipids to enhance the skin's natural ability to retain moisture, EFA treatment which Is an Important component of the skin's moisture barrier, humectant to bind water In the skin's outermost layers, and occlusives to block moisture loss. I tried using many other lotions, but this one has worked best for me when It comes to dry skin and Itching.
What about anti itch cream?
My breast went from a 34c to a 40d in the first couple weeks I was pregnant (mainly my first trimester), they never really itched to bad, but they did hurt like hell! Although I already had stretch marks, I think I might of gained a few more. I would just continue to put lotions and oil on them to help with the discomfort until they stop gettin so big lol
