What are the red, swollen bumps under eyes?

Red, swollen bumps underneath the eyes are either acne keratosis pilaris, chalazia or styes. These bumps can also be caused by allergic reactions to cosmetics.

Oily skin can cause a buildup in the pores around the eyes and create pimples caused by acne. These can be treated by over-the-counter acne medications. Dry skin can cause a buildup of dead skin cells, leading to the development of bumps that look like tiny pimples but are actually a symptom of keratosis pilaris. This condition is not curable, but a dermatologist can prescribe medication that can lessen the symptoms.

A painful bump on the edge of eye can indicate an infection in a hair follicle that has caused a stye. There are many home remedies and over-the-counter treatments that can help with this condition. A chalazion looks similar to a stye but is slightly larger and not painful. The same methods for treating a stye can be used to treat a chalazion. Itchy bumps may indicate an allergic reaction to cosmetics. Those who experience a sudden occurrence of itchy red bumps after using a specific cosmetic should discontinue using that product.

Those experiencing pain, itchiness and swelling or have bumps that obstruct vision should contact a health care professional for diagnosis and treatment.
