Does contact dermatitis following ablative laser surgery increase chances of keloid formation?

Question

I have a history of keloid - I have a small one on my chest and my mother has them too. I received ablative laser surgery on a 1x1cm spot on my cheek recently for a sunspot. All was going well but 12 days post procedure, I developed contact dermatitis in response to a sheet mask. I used 1% hydrocortisone cream + Cicaplast Baume B5 to treat the inflammation. I am now very worried about keloid formation . What is your take on this?

Given your history of keloids and the recent contact dermatitis on the treated area, it’s understandable to be concerned about keloid formation.

To minimize the risk, it’s important to follow your dermatologist’s aftercare instructions diligently. If you notice any signs of abnormal scarring or if the area appears to be developing a keloid, it’s crucial to reach out to your dermatologist promptly.

Keep the area well-moisturized and avoid any further irritation or trauma. If you have concerns, a follow-up appointment with your dermatologist can provide a more personalized assessment and guidance based on the specific characteristics of your skin and the recent contact dermatitis

Contact dermatitis following ablative laser surgery does not typically increase the risk of keloid formation. Contact dermatitis is an inflammation of the skin resulting from direct contact with certain substances. While it can cause discomfort and skin irritation, it does not usually influence scar formation.
Keloids, on the other hand, are an overgrowth of scar tissue that occurs where the skin has healed after an injury. They are more likely to form in people with darker skin tones and in areas of the body where the skin is under tension, such as the chest and back. Keloids are also more likely to form following more invasive or traumatic skin procedures.
However, any skin inflammation, including severe cases of contact dermatitis, could potentially contribute to abnormal scar formation in individuals who are prone to keloids. It's also worth noting that improper care of the skin after ablative laser surgery could potentially increase the risk of complications, including abnormal scar formation.
Therefore, it's important to follow all post-procedure care instructions provided by your dermatologist or plastic surgeon, and to notify them if you notice any signs of contact dermatitis or other adverse reactions following your procedure.
