| Do you use Preparation H? |
You probably have heard about the beauty trick of using Preparation H to reduce swelling of puffy eyes and help with wrinkles and beautifying a complexion. Top makeup artists, celebrities, models, and beauty contestants swore by its wonders for those purposes. However, those results were based on the original formula that had a live yeast cell derivative (LCD), which is also referred to as Bio-Dyne.
Unfortunately, the formula underwent a change in 2007 where that ingredient was replaced with phenylephrine HCL. Being a vasoconstrictor, this ingredient is a topical steroid that works to constrict blood vessels just like the phenylephrine in sudafed. Temporarily, you might see swollen eyes deflate since the blood and fluids have a limited flow. You may think this is a good thing and even be tempted to use it, but you are making a mistake.
