There is hormone change in my 1st trimester pregnancy where my pimples take turn circulates around my right cheek while left cheek has nothing. Besides, my face skin dry and peel off easily. Luckily that was just a few pimples and dry skin gone after awhile. Besides, i understand cosmetics/ beauty product where the contained chemical will affect to fetus development. I only apply face moisturizer. There was no cosmetics, no lipsticks, no hair salon treatment throughout my pregnancy. Anyway, I still can maintain my pretty face and my body shape throughout the pregnancy. :p
