Nearly one in two (48.5%) individuals self-report having a scar on their body; more specifically, the percentages per country are as follows: China (37%), Brazil (46%), the United States (53%), Russia (61%) and France (51%).
Approximately one in five subjects (22%) report the focal scar to be less than 1 year old. The average number of scars reported does not differ according to gender (4.1±4.9).
Despite the high frequency of scars, no evaluation has examined the impact of scars in terms of discomfort, pain or unpleasant sensations, or changes in the scar (positive, negative, or no change) according to certain situations; for
example, climatic and daily life factors have never been evaluated in real-life studies
