wish I could give some advice to help but like my obgyn told me...there really isn't anything I can do since the hormones are going haywire because of the baby. I could really use any topical treatments because of their absorption into the skin. I had bad pimples pretty much through out my whole pregnancy, skin rosacea then a thing called PUPP towrads the end which were little pimple like pustules all over my body.
All I can say is to pamper yourself as much as possible, give yourself mild facials and gentle masks at home or a spa, anything to make you FEEL better because actually making it clear up is up to your pregnancy hormones and nothing you can do from the outside.
If it any consolation, as miserable as my skin was..my bouncing 10 month son was WELL worth it. And I am sure your healthy little one will be too
