While scholarly research papers specific to neck aging loss of firmness/ elasticity are limited, rows 13 - 16, columns M - R of the attached spreadsheet have been completed with scientific research and articles related to neck skin aging in general.
- A study to evaluate the safety and efficacy of "a novel two product combination system composed of a serum and cream with hyaluronic acid and multiple strong antioxidants" in the rejuvenation of the neck skin found that "both active and placebo cream and serum showed improvement of wrinkles, laxity, pigmentation, erythema, dryness, and texture of the skin, and high patient satisfaction scores."
- A study found that "consumption of hydrogen-rich water has a positive effect on neck skin aging."
- A research paper identifies chloracnegens as an environmental pollutant that affects the neck, causing chloracne. Chloracne "is a systemic toxic disease caused by exposure to chloracnegens (halogenated aromatic hydrocarbons). It is characterized by acneiform skin lesions such as comedones and cysts mainly on the face (outer sides of the eye and behind the ears) and neck."
Our research team initially focused on finding data specific to neck aging/loss of firmness/elasticity and the changes caused by environmental factors, seasonal changes, and lifestyle changes. We thoroughly searched various scientific research databases such as Wiley Online Library, Science Direct, Elsevier, Springer, US National Library of Medicine
and National Institutes of Health, and Google Scholar in general. While we were able to find few articles or research papers that specifically mentioned neck aging but changes or effects due to environmental and/or lifestyle choices which we have reported, most of the papers simply treated the neck as part of the skin in general and factors relevant to skin aging, in general, were expected to apply to neck aging and as such the papers were not specific to just the neck skin. Given the paucity of research papers available specifically for neck aging, our research team has had to include sources that are more related to the skin in general but that also apply to the skin in the neck in the spreadsheet. Please note that we have also had to extend to sources beyond two years but that is still relevant and are still widely cited today.
