Are you in love with serums as much as I am? (Read <a href="http://beautyeditor.ca/2009/12/30/editors-pick-this-works-active-serum/">here</a> and <a href="http://beautyeditor.ca/2010/03/31/how-to-treat-oily-skin-hormonal-acne-and-post-acne-marks/">here</a> if you need to get up to speed.)

If you're already a devotee, I have a tip for you: make sure you wait at least 5 to 10 minutes after you apply your serum to let it fully absorb into your skin.

If you apply your moisturizer too soon, you could be diluting the product and not getting the full benefits. (And trust me—serums, because of their liquid nature, can hold on to TONS more good-for-your-skin active ingredients than your moisturizer can.)

This is something I was doing until very recently, but now I know better... and so do you!
