What are the signs that I need to visit a dermatologist with my after-pregnancy skin woes?

Pregnancy can generate blood moles and red spots, if these are still visible a year after giving birth, you may want to visit a dermatologist to burn off red spots and blood moles. If any of your moles changed in size, shape or colour, or you have any new black moles, visit a dermatologist. Maternity hormones make moles more susceptible to developing pre-cancerous cells.
