I get frequent questions about individual anti-aging ingredients. Can it REALLY reverse aging? Is it natural? Dangerous? Last time, I reviewed idebone, a powerful antioxidant. Today I’m evaluating ceramides. I’ve seen it advertised on a number of products and thought it was finally time to do a little research.
Here’s how it works: The cells of the top layer of the skin are held in place by fatty ceramides, a substance which kind of acts like glue to keep the cells in order. In addition ceramides hold onto water molecules, helping to attract and retain moisture in the skin. And it will probably come as no great surprise that ceramide levels decrease as we get older. By age 60, we have lost so much ceramide that the upper layer of the skin is 30% thinner.
This week the questions concern antioxidants. They seem to be everywhere and in every type of beauty product:
Question 1— Which is more important for anti-aging skin care- antioxidants or Retin A?
Answer — These two wrinkle fighters work in different ways. Antioxidants act to reverse cellular damage caused by UV rays. Retin A works by returning skin cell growth to youthful levels, promotes exfoliation of old tired skin cells and encourages growth of new strong collagen. Its not a matter of which is better– you really need them both, especially in the long sunny summer days. What’s really good news that they are an excellent tag team for reversing skin aging. Each offers unique benefits and they don’t interfere with each other. At night top your Retin A with an antioxidant rich moisturizer. During the day, anti0xidants in a sunscreen add … Continue Reading… →
Sometimes anti-aging ingredients and skin care product descriptions sound like a review sheet for a medical board exam. This week questions about two anti-aging ingredients sent me to Pub Med, the NIH online medical library for the answers.
Question 1– What is Idebenone?
This is a synthetic antioxidant that is designed to mimic CoQ10, a naturally occurring oxidant found in our cells. (FYI CoQ10 which is responsible for energy, decreases as we get older). Idebenone is an especially powerful antioxidant, perhaps the most powerful antioxidant in our anti-aging arsenal. Antioxidants in general help prevent aging by dealing with free radicals in the cells. Our biggest sources of free radicals are cigarette smoke, alcohol and sunlight. It certainly makes sense to put antioxidnts into a sunscreen where it can do hand to hand combat with … Continue Reading… →
