The S.A. Popravko Laboratory is a natural beauty company specializing in skin care products featuring Northern Russian birch propolis. This type of propolis was first identified and characterized by the Russian biochemist Dr. Sergei A. Popravko in 1969-1973.His pioneering research led to the discovery of the natural source and chemical composition of the northern Russian propolis. This type of propolis is collected by honeybees in the northern and northeastern part of Russia from the buds of birch trees (Betula Sp). Birch propolis is perfectly balanced in its chemical composition and biological activity and is the most hypoallergenic type.In the 1980s Dr. Popravko also formulated a new type of nourishing skin care emulsion designed to imitate transdermal honeybee larvae feeding during their development in sealed wax cells. "The Queen's Morning" became the first commercially available cream based on this new type of emulsion, serving as a solid foundation for a new line of skin care products. In over 25 years on the Russian market the S.A. Popravko laboratory has become an established brand among natural skin care product companies. The entire product line is certified to be completely natural and does not contain any artificial ingredients and additives.
