Can Chickenpox Trigger Keloids? Tips for Prevention and Care - Dermatology

Does having chickenpox increase the likelihood of developing keloids?


Hello, doctor.
I have a keloid tendency and did not have chickenpox when I was younger.
I would like to ask if I do get chickenpox, will the areas affected definitely form keloids, or can I avoid keloid formation as long as I do not scratch the lesions? If I unfortunately contract chickenpox, how can I prevent the wounds from developing keloids? Thank you, doctor.
I've been quite worried about getting chickenpox and have recently received the chickenpox vaccine.
Additionally, could you please clarify if monkeypox, which is currently spreading abroad, is similar to chickenpox? If one contracts monkeypox, is it also likely to result in scarring? Thank you, doctor.

Chickenpox scars are generally more often depressed scars, while monkeypox is more similar to smallpox.

More Info


Chickenpox, caused by the varicella-zoster virus, can indeed lead to the formation of keloids, especially in individuals who are predisposed to keloid formation, such as those with a history of keloids or certain skin types. Keloids are raised scars that occur when the body produces too much collagen during the healing process. While not everyone who contracts chickenpox will develop keloids, those with a keloid-prone skin type may be at a higher risk, particularly if the chickenpox lesions are scratched or improperly cared for.

To minimize the risk of keloid formation if you do contract chickenpox, here are some tips:
1. Avoid Scratching: One of the most crucial steps is to avoid scratching the chickenpox lesions. Scratching can lead to skin trauma, which increases the likelihood of keloid formation. Keeping your nails short and wearing gloves at night can help prevent scratching.

2. Keep the Skin Moisturized: Applying a gentle, fragrance-free moisturizer can help keep the skin hydrated and reduce itching. This may help prevent the urge to scratch.

3. Use Anti-itch Treatments: Over-the-counter treatments such as calamine lotion, oatmeal baths, or antihistamines can help alleviate itching and discomfort associated with chickenpox.

4. Proper Wound Care: If any lesions do break open, it's essential to clean the area gently with mild soap and water, and cover it with a sterile bandage to protect it from infection. Keeping the area clean can help minimize scarring.

5. Consult a Dermatologist: If you have a history of keloids or are particularly concerned about scarring, consult a dermatologist. They may recommend treatments such as silicone gel sheets or pressure therapy after the lesions have healed to help prevent keloid formation.

Regarding your concerns about monkeypox, it is important to note that while both monkeypox and chickenpox are viral infections, they are caused by different viruses and have different characteristics. Monkeypox is caused by the monkeypox virus, which is related to the smallpox virus, while chickenpox is caused by the varicella-zoster virus.
Monkeypox can lead to skin lesions similar to chickenpox, but the lesions may be more severe and can also be accompanied by other symptoms such as fever, swollen lymph nodes, and body aches. The risk of scarring from monkeypox lesions can also be present, especially if the lesions are scratched or infected.
In summary, while chickenpox can trigger keloids in susceptible individuals, careful management of the skin during the infection can help minimize this risk. If you are concerned about keloids or have a family history of them, it is wise to take preventive measures and consult with a healthcare professional. Additionally, understanding the differences between chickenpox and monkeypox can help you stay informed and prepared for any potential health issues.
