I am one year post partum and I have very visible stretch marks. I started using Retin A ointment on my stretch marks from July. I use it twice a week. So far I have not faced any problem. The last one week, I have severe rashes all over my stomach. It was very itchy and I ended up scratching it pretty bad and hence the rashes. I have discontinued Retin A since the last one week. I use Retin A even  on my face and I have not faced similar problem. I use Cetaphil soap and moisturizer. Kindly suggest how do I take care of the rashes. Thank you.
