Problems with Dermapen – pustules and bumps

I had Dermapen exactly seven days ago. In the areas I had the treatment, I broke out with three, small puss-filled looking pimples. They had come to a head, and looked very protruding. So, I popped them gently. I then cleaned them and put benzoyl peroxide on. Two days later, the skin on top peeled off. Now, I have slightly swollen, raised bumps where they were. Will these go down?

Okay so this is exactly what I’m concerned about with these devices.   When you puncture the skin, you are causing damage to the barrier layer.  Dermapens and other needling devices can cause infections, if not used correctly or if you are already a staph carrier.   About 20% of the population cares staph chronically – usually in inside of the nose.  

Having said that, I really think you need to see your doctor and get a culture done.   It’s important not to just treat with antibiotics before the culture, because you don’t know for sure what’s growing in your skin without a culture. 

In our clinic, we culture rashes, pustules, and other skin lesions frequently and often get other bacteria besides staph.   And, it’s helpful to know if it’s MRSA or not – which is the more dangerous, aggressive form of staph.   You won’t know that without a culture.   Antibiotics can be started as soon as the culture is done, if needed.

Hope this helps,  Dr. I

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes!
