333 THE STATE OF SUSTAINABLE PRACTICES
appearance. As a result, sensitive skin is typically identified through questionnaires or self-
reports, with additional tests, like the stinging or capsaicin tests, sometimes used, though
they have limitations.
Sensitive skin is increasingly recognized as a multifactorial and neuropathic primary
disorder with a wide range of potential causes, rather than a secondary symptom of
other skin conditions, like atopic dermatitis. While a variety of environmental, physical,
chemical, and psychological factors have been identified as potential triggers, cosmetics
are the most significant contributor, far outweighing other factors such as temperature
fluctuations, pollution, or emotional stress. Despite this, sensitive skin is not considered
an immunological disorder rather, it is linked to disruptions in the skin’s nervous system,
with skin barrier abnormalities often present, though not directly related.
Recent studies suggest that sensitive skin may be a neuropathic disorder, further
highlighting the role of the nervous system in its pathophysiology. This has led to calls
for more sophisticated research models, such as co-cultures of skin and sensory neurons,
to better understand the underlying mechanisms. However, clinical evaluations remain
crucial, as one of the major challenges in studying and diagnosing sensitive skin is the
absence of objective, standardized tests to aid in the diagnosis of this condition. Most
evaluations rely on self-reported questionnaires, which assess the presence of sensory
symptoms without confirming their underlying cause. This makes it difficult to
distinguish between normal skin and sensitive skin, as there is no clear-cut boundary.
Some researchers propose setting cut-off points to help define sensitive skin, but these are
necessarily arbitrary, given the spectrum of sensations that can range from mildly sensitive
to highly reactive skin.
To substantiate cosmetic claims, sensitive skin panels are often used to assess whether
cosmetic products exacerbate or improve symptoms. However, the reliability of these panels
is frequently called into question, as many are inadequately defined. A well-constructed
sensitive skin panel must meet two critical criteria: 1) there must be no skin disease
present, and 2) the positive criteria for sensitive skin must be clearly outlined. Without
these foundations, it’s impossible to separate true cases of sensitive skin from other skin
conditions.
Despite the challenges, there is growing evidence supporting the idea that sensitive skin
is a distinct and significant dermatological issue, and research is progressing in ways that
may offer new insights. Future research will need to focus on refining diagnostic criteria
and developing better testing methodologies. Only then can the mechanisms at play be
understood to allow treatments, including cosmetic products, to be properly tailored to
alleviate the discomfort of those with sensitive skin.
Sensitive skin is a multifaceted syndrome that requires more than just symptom
management it demands a deeper understanding of its pathophysiology, precise diagnostic
criteria, and reliable testing methods. As research evolves, so too will the ability to define,
diagnose, and treat this increasingly prevalent condition.
Understanding the Vicious Cycle of Sensitive Skin Syndrome. Dr. Farage reports that Sensitive
Skin Syndrome is a major malady that affects a significant portion of the population, with
nearly 40% reporting moderate to severe sensitivity and another 30% experiencing mild
symptoms. This condition, marked by sensations like itching, burning, stinging, pain, and
tingling, can affect anyone and can manifest on any part of the body. Environmental and
