In order to reduce facial swelling caused by Proactiv, it is important to discontinue use of the product as this may be a severe allergic reaction to the ingredients benzoyl peroxide or salicylic acid. For an allergic reaction that causes hives, facial or eye swelling or breathing difficulties, it may be necessary to seek prompt medical attention, states the National Institutes of Health's MedlinePlus.
Terminating the use of Proactiv and having any symptoms that occur related to its use treated by a physician is the only way to completely cure a Proactiv-swollen face.
Proactiv is the brand name of different topical acne products that contain the active ingredients benzoyl peroxide and salicylic acid, notes the Proactiv website.
This product may cause only mild skin side effects in some users, such as dry skin and mild irritation. In rare instances, other users experience more severe side effects caused by these active ingredients, including nausea, tight throat and diarrhea. Overuse of a product with benzoyl peroxide can also lead to an overdose that may result in side effects like red and scaly skin, notes Mayo Clinic. Using too much of topical creams with salicylic acid can also cause an overdose with side effects that range from vomiting to mental confusion, according to MedlinePlus.
