Used Strivectin, Now Have Bags Under Eyes. Are These Sudden Bags from Fat or Muscle That Has Moved?

Strivectin and other eye creams can cause swelling of the eyelids due to an allergic reaction or irritation of the skin caused by the cream.

True eye bags are caused by herniation or protrusion of the fat inside the eyelid pushing against the skin of the eyelid. This is part of a normal aging process and is not caused by skin creams.

The irritation of the eyelids caused by eye creams will go away after the cream is discontinued. True eye bags or puffy eyes caused by fat herniation will not.

  Not all lower eyelid bags are excess fatty tissues, as apears to be the case here.  Swelling can also cause bags under the eyes but this is not something that can be removed with a lower eyelid surgery or Blepharoplasty.  This is how I teach my eyelid surgery consults to tell the difference between lower eyelid swelling and fat.  Take a look at your eyes in the early afternoon, when the typical swelling of sleep is gone, if you see bags under your eyes these are most likely fat and they should not get smaller throughout the rest of the day.  Fat bags, of the eyelids, occur slowly over many months and years and do not show up suddenly...swelling does.

 IMHO, it sounds like you may have had a tpoical alllergic reaction to the cream and you may want to foillow up with a dermatologist for localised treatment to decrease the swelling.
