A recent study in Estonia of 348 randomly selected workers over 30 years of age found that 22 percent had one or more primary features of rosacea,¹ as identified in the standard classification system developed by the National Rosacea Society consensus committee and review panel of rosacea experts. The Slavic nation is located off the eastern Baltic Sea.
