Toenail Fungus and Nail Polish – Do They Mix?

  Yes! It’s okay to put nail polish on infected nails but remember, you’re not curing it, you’re just covering it up.

Best is to use the prescription Penlac (now available in an inexpensive generic – less than $20 at Costco) medicated clear polish as a base coat. Put 2 coats of this on the nails and then your polish over it. File the nail down per directions with the Penlac (over the toilet) before applying polish. Change the polish every 2 weeks.

Try to go without polish in the winter so you can use the Penlac more often as directed in the instructions. This will at least help control it even if unlikely to cure it.

There were lots of searches for Latisse on SkinTour.  Allergan’s marketing must be having an effect!  See Dr. Irwin’s opinion of Latisse.

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?!
