Body Paints Safe for Pregnant Women

Tips for Painting Your Baby Bump Safely
Always do a patch test on a small area of skin 24 hours before painting your full bump. Choose water-based, non-toxic paints labeled safe for skin. Avoid paints with alcohol, strong solvents, or heavy fragrances. Remove the paint gently with warm water and mild soap after the event. If you have any concerns, consult your OB/GYN before using any body paint during pregnancy.
