Make-up Forever HD or Laura Mercier Silk Creme foundation?
Answered[ Edited ]
Since you have bad acne, I wouldn't recommend either of those foundations for you. You need to use a foundation that won't clog your pores.
I would try Clinique Acne Solutions Liquid Makeup because it has great coverage, neutralizes redness and is medicated to help current and prevent future breakouts. You can find it at: http://sephora.com/browse/product.jhtml?id=P259605&categoryId=B70
You can also use Clinique Acne Solutions Clearing Concealer for any hard to cover blemishes. It is medicated, too, and you can find it at: http://sephora.com/browse/product.jhtml?id=P244700&categoryId=B70
Between the concealer and foundation you should have plenty of natural-looking coverage for your acne.
I hope this helps you.
