I have a lot of pimples on my chest and back and I am pregnant. I have been using Benzagel and Ducray cleanser, but it's getting worse (very dry skin). What should I do?

Based on the conversation, it seems like the user has been experiencing a lot of acne on their chest and back, as well as dry skin. They have been using Benzagel and Ducray cleanser but have not seen improvement. They are considering using a different moisturizer and wondering if it will help reduce redness, itching, and burning sensations, as well as the number of pimples. They are also unsure if just moisturizing will be enough to get rid of the pimples. It is recommended to stop using Benzagel and switch to a Ducray cleanser and moisturizer for at least 4 weeks before evaluating if it is helping.
