Pregnancy often triggers skin issues like acne and flare-ups due to rapid hormonal shifts that increase oil production, leading to clogged pores. Dr. Kunal Sood explains that these changes, which can affect the face, back, chest, and shoulders, are common and linked to internal bodily changes. He advises focusing on gentle skincare habits, using mild cleansers and non-comedogenic moisturizers, as pregnancy makes skin more sensitive and reactive to harsh products.
