Understanding Lip Plumpers

Before we explore the possible link between lip plumpers and cold sores, it’s essential to understand what lip plumpers are and how they work.

The relationship between lip plumpers and cold sores is a valid concern for individuals considering these cosmetic products. Let’s explore what New York City board-certified dermatologists have to say about whether lip plumpers can potentially cause cold sores, drawing insights from their expertise in dermatology.

Expert Opinions from New York City Dermatologists:

  1. Dr. Shereene Idriss: Dr. Idriss, a board-certified dermatologist based in New York City, suggests that lip plumpers themselves do not directly cause cold sores. However, she cautions that the ingredients found in some lip plumpers, particularly those with strong irritants like cinnamon or capsicum, can potentially trigger cold sores in individuals who are already carriers of the herpes simplex virus (HSV).
  2. Dr. Michele Green: Another prominent NYC dermatologist, Dr. Green, points out that lip plumpers, by causing irritation or micro-inflammation on the lips, may activate the herpes simplex virus in those who carry it but have been asymptomatic. This activation can lead to the development of cold sores.

Key Considerations:

Individual Sensitivity

It’s crucial to recognize that not everyone who uses lip plumpers will experience cold sores. Individuals vary in their sensitivity to the ingredients in these products, and some may be more prone to cold sore outbreaks than others.


If you are concerned about cold sores and wish to use lip plumpers, Dr. Idriss recommends conducting a patch test before using the product on your lips. This can help identify any potential sensitivity or allergic reactions.

Herpes Simplex Virus (HSV)

Cold sores are primarily caused by HSV, and the virus can be transmitted through close personal contact. If you have a history of cold sores or are unsure of your HSV status, it’s essential to be cautious when sharing lip products or engaging in activities that involve close contact with others.


Dr. Doris Day, a respected NYC dermatologist, emphasizes the importance of maintaining good hygiene when using lip plumpers. Ensure that the applicator or your hands are clean to minimize the risk of introducing any external pathogens to your lips.

  3. Maintain Lip Health: Keep your lips well-moisturized and protected from harsh weather conditions, as healthy lips are less likely to develop cold sores.
  4. Consult a Dermatologist: If you are prone to cold sores or have concerns about using lip plumpers, consult a dermatologist for personalized advice.
