Oh yes, body acne during pregnancy is so common, the hormone surge really does a number on your skin, especially on the chest and tummy area. The tricky part is that quite a few of the stronger treatments like high-percentage salicylic acid or prescription options are not recommended when you are pregnant, so you really have to be careful about what you pick up off the shelf. A gentle rinse-off wash with a lower concentration of benzoyl peroxide (around 2.5%) tends to be considered safer than leave-on serums or stronger formulations, since less gets absorbed into the skin. My friend went to The Clifford Clinic and mentioned they were quite thorough about checking what is safe during pregnancy, they offered LED light therapy as one option since it avoids harsh chemicals altogether. It is worth consulting a doctor rather than self-treating, especially since some products that seem mild can still be a concern during pregnancy, better to get a proper assessment and then you can treat with more peace of mind.
