“…A study showed that 'Caucasians' with sensitive skin more often claimed that products produced visual effects, whereas 'African Americans' more often claimed that products produced sensory effects [44]. Japanese women react more intensely than German women, although there is no difference in the neurosensory innervation of the skin [45]. A role for phototype has also been suggested [46].…”

Sensitive skin could be defined as the occurrence of erythema and/or abnormal stinging, burning and tingling sensations (occasionally pain or pruritus) in response to multiple factors, which may be physical (UV radiations, heat, cold and wind), chemical (cosmetics, soaps, water and pollutants) and occasionally psychological (stress) or hormonal (menstrual cycle). The diagnosis, pathophysiology, epidemiology and treatment are still under debate. Sensitive skin is most likely due to neurogenic inflammation after the enhanced activation of sensory proteins in keratinocytes and nerve endings. Skin sensitivity is a very frequent condition because it can be detected in approximately half of the population. The treatment is likely a cautious use of cosmetics or the use of cosmetics without preservatives and surfactants or containing inhibitors of neurogenic inflammation.

“…Ethnic variation in skin sensitivity is also reported [2,[5][6][7][8][9][10][11][12][13][22][23][24] but this may be influenced by geographical location, sun exposure, the season of the year and cultural differences. However, despite similarities in perception of sensitive skin, Asians are reported to be more sensitive to stinging tests than Caucasians [25].…”

“…Several studies have also investigated some of the physiological, biochemical and cellular changes in sensitive skin [22]. Compromised barrier function is believed to be one of the factors that facilitates the onset of skin sensitivity [20,[32][33][34][35][36][37].…”

Despite the physiological similarities between the two groups of sensitive skin subjects, differences in their biochemistry were clearly evident. Lower levels of PCA, BH and TG activities together with a greater number of smaller and immature corneocytes indicate inferior SC maturation in the capsaicin-sensitive subjects. The reduced maturation of corneocytes and thinner SC likely contributes to a greater penetration of capsaicin and the associated increased skin sensitivity.

“…The increased level of epidermal melanin in darker skin confers advantages in that its photoprotective nature reduces the risk of skin cancer and photodamage to the skin 1–6 . It carries disadvantages, however, because it makes the skin more reactive to stimuli, and thus susceptible to postinflammatory dyspigmentation 1,2,4–7 . Skin of color, particularly black skin, is also predisposed to hypertrophic or keloidal scarring 1,5–10 .…”

“…It carries disadvantages, however, because it makes the skin more reactive to stimuli, and thus susceptible to postinflammatory dyspigmentation 1,2,4–7 . Skin of color, particularly black skin, is also predisposed to hypertrophic or keloidal scarring 1,5–10 . Due to these characteristics of darker skin, it is important to determine whether the theoretically greater potential for adverse events from dermal filler injections is demonstrated in clinical practice.…”
