A microneedle roller question.

Hi Dr. Irwin, What do you think about the effectiveness of micro needle rollers for collagen formation? And how often should one use a needle roller for good results? I have also read conflicting accounts about the safety of using needle rollers with retin-a. Should I stop using retin-a if I try the needle roller?

Can you send me the exact type you are thinking about using?  It really depends on the size of the microneedles, directions for use, etc.   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! 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?!
