Doctors often hear “I went sleep one night, and woke up the next morning with wrinkles.” While overnight may be exaggerating a tad, it turns out that facial wrinkling may be more abrupt in onset than common sense might suggest. Something critical seems to happen with the response to mechanical forces (e.g. facial muscle movement, gravity, etc) at the junction of skin layers during the first part of the fourth decade of life. According to a study just published (see abstract below) the forces that previously might result in fine lines would instead induce deep furrows. And at a still tender age.

Does the morphology of wrinkles alter gradually with aging or suddenly at a certain age? On the basis of the theoretic wrinkle simulation of ideal skin, we have suggested that the wrinkle morphology suddenly changes from stratum corneum wrinkling to epidermis wrinkling; the former induces shallow fine furrows, and the latter induces deep prominent wrinkles. To examine the existence of drastic change in wrinkling morphology, we developed a new measurement system for facial skin wrinkling test.
The mechanical compression test of facial skin was carried out for 102 Japanese women aged 25-56 years. The test was performed on the right temple area skin, and the area of wrinkles induced by the compression was measured using a digital video camera. The rate of increase in wrinkle area during compression was defined as the skin wrinkling rate, and it was calculated for all subjects automatically by image processing.
The test results showed that the skin wrinkling rate underwent a step increase at the age 33, which means that the wrinkling morphologies of young and old skins are completely different, and so it changes suddenly in the early 30s.A new skin measurement system was developed to validate our theory of wrinkle formation mechanism with aging. The results demonstrated the wrinkling morphology changes suddenly at early 30s.
There are also some other lines of evidence pointing to the early 30’s as a critical time in the continuum of skin aging, relating back to stem cell biology and cytokine signalling systems. We will explore some of those in upcoming posts.
We are planning to expand our content here at BFT, and in particular want to share with you some of the latest information about skin aging. An in depth understanding of the dynamics of aging skin leads to a much clearer perspective in terms of determining approaches to prevention and rejuvenation strategies. There are many ways to look at aging — from the macro (organ/tissue level) to the micro (cells and extracellular components) to the nano & pico (subcellular, molecular).
