Skiing and Cold Sores

Remember that sun, especially at altitude, triggers cold sores. So protect your lips when you’re skiing, boarding, sledding, mountaineering, or snowmobiling.

Use tons of lip sunscreen or chapstick with sunscreen to prevent cold sores.

And take your prescription for Famvir or Valtrex twice a day for 5 days at the first sign of a cold sore. Call your primary care or dermatologist for a prescription if you don’t have one. Take it with you when you travel!

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!
