According to a recent study out of Taiwan, scientists have found that a new laser technique may help to determine the skin’s age. Using harmonic generation microscopy, researchers were able look beneath the skin’s surface and found that natural aging (which doesn’t take into account environmental stressors like excess sun exposure and smoking) resulted in an increase in basal keratinocytes, the most common cells on the outermost layer of skin. Other granular cells did not show the same pattern. Basically what it boils down to is that the difference in cellular changes can be used to help gauge natural (intrinsic) skin aging and the discovery of a standardized skin age index is definitely a breakthrough.
So what does all this mean for us? While you may not be able to continue repeating your 29th birthday, there are some serious benefits to this new discovery that we can all look forward to. For one, it might provide doctors and dermatologists with a new method of monitoring skin’s health, including whether it’s aging faster than what would be considered average, which could further help customize anti-aging skin-care regimens. It might also provide a barometer for testing the effectiveness of anti-aging products as well as procedures and treatments.
