My Questions on Dermarollers and Microneedling

Notice that the so-called “science” on all the websites and devices………is just a general description of a wound healing response.   It is NOT a description of any science done with their particular device in human skin.   I still see many unanswered questions with these, like:

  • How are the companies making sure they aren’t selling these to untrained people?
  • When you puncture skin you greatly increase infection risks.  How is this being addressed?
  • How is pain being addressed with the deeper (>1mm) pens?  At that depth, a peel is more uniform.
  • For the “dermal” pens, how are they preventing scarring with the wider needles that leave a visible puncture mark?
  • Darker skin types may have temporary or permanent darkening; how is this addressed?

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! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
