Preparation H DOES work on wrinkles.
More Info: Preparation H can have a short term effect on wrinkles, tightening up the skin where it is applied. It also works well on bags under the eyes.
How Does Preparation Work?
Preparation H, at least as it is sold in the United States, contains phenylephrine, which is a vasoconstrictor. That is, it causes blood vessels to constrict. Taken orally, phenylephrine type drugs are used to reduce sinus pressure and nasal congestion by constricting the blood vessels. Topical use of phenylephrine in Preparation H works in the same way by constricting the capillaries just under the skin to reduce swelling and causing the skin to tighten, temporarily reducing wrinkles.
How to Use Preparation H for Wrinkles
Apply a small amount to the area of concern, gently rubbing the cream into the treatment area. Be careful not to get it into the eyes. Remember that the skin around the eyes is very sensitive, so always treat this area gently.
