Can I search the site by keywords – antioxidants, fragrance?

Hi Dr. Irwin, is there a way to check blog questions by key words? For instance, I was trying to check what your thoughts are on fragrance in skin care, and loss of efficacy for antioxidants in jar products. Thanks for all the information you provide.

You’re welcome! We don’t have that functionality at this point but hope to add it someday. The most likely place for info on that would be under blog content then skincare products.

Briefly though, antioxidants lose potency more quickly from jars than enclosed pumps because exposure to oxygen can degrade them. Fragrance is tricky because most are chemical, rather than extracts now but there’s no requirement to divulge that on the packaging so it’s difficult to find this information.

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?!
