Tom Mammone, executive director of Clinique Research and Development, talks about how stress affects ageing and the benefits of Clinique’s latest product, Superdefense SPF 25/PA+++ Age Defense Moisturizer.
Does stress really affect ageing?
When your body is under stress, it releases hormones including adrenaline and cortisol. These stress hormones can cause irritation and loss of immune function in the skin and the effects of this are very similar to what happens during the natural ageing process. When skin is irritated it can lead to a compromised barrier function. A strong barrier keeps moisture in and external aggressors and irritants out. When the barrier is damaged, moisture evaporates more rapidly and irritants can get in more easily, both of which cause damage to the skin. In addition, when the immune function of skin is compromised, its ability to fight off external invaders and suppress damaged cells before they multiply is also compromised.
Why did you choose to approach age prevention this way?
We have had anecdotal evidence for a long time that psychological stress can affect skin. One of the best examples is to look at pictures of politicians that have had to deal with particularly stressful times during their terms. The difference between the pictures before they held office and after can be dramatic. This topic is one that has long been of interest to us so when the opportunity for Clinique scientists to do targeted research on the subject came about, we took it. The findings from our study confirmed that emotional or psychological stress can damage skin’s natural defences. In addition, the research led us to have a clearer understanding of how psychological stress can damage the skin and armed with this knowledge, we were able to look into ways to combat this visible damage topically.
