Bulges may make their debut, as faulty valves and weak vascular walls prompt a backup of blood. Pregnancy hormones and belly weight can cause dilation and stretching, allowing blood to pool, says Luis Navarro, a NYC phlebologist (vein specialist). Use an antioxidant lotion like Nivea Skin Firming Moisturizer with Q10 ($10) to protect firming collagen proteins, says NYC dermatologist Joshua Zeichner, and give compression stockings a try for four days or nights a week; they squeeze veins to up circulation and prevent them from appearing worse over time. Try Rejuva-Health Pantyhose ($70).
