What Is “Glow?”

  "Glow" is a subjective term, but somehow we all know it when we see it. Just look at children’s skin!

Glow is caused by several factors. The most important is the eveness of the skin’s outer layer (stratum corneum). The more even it is, the more the skin reflects light.

Other factors are the quality and number of the blood vessels nourishing the skin, the health of the second layer (epidermis) which gets damaged by UVA and B, and the thickness and health of the collagen (deeper in the dermis).

Next week – how to get your glow back.

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?!
