All DZINTARS products pass the tests carried out to evaluate the quality of products on the development stage. The testing takes place on several stages: physicochemical and microbiological testing, express-testing at “harsh” regimes (critical temperatures from –20 ºС to + 50 ºС), toxicological evaluation and clinical probation on not less than 33 participants under supervision of medical specialists. New products are being tested by a dermatologist, the testing of eye zone care products and mascara are carried out by an ophthalmologist. A highly skilled expert-toxicologist controls products safety for use.

One of the most important testing phases is the confirmation of declared consumer characteristics. Consumer features of all products are determined according to our very special methods within 4 age groups (14-18 years old; 19-35 years old; 36-50 years old; over 50 years old) with 80 persons in each group being questioned. For instance, a new perfume is being launched only if not less than 90% of each age group agrees on liking its fragrance. In addition, we implement the so-called "blind testing": participants are requested to compare the DZINTARS perfume with a perfume of another famous brand (all products are presented in the same bottles). In order to reach the retail counter, the DZINTARS fragrance must be the best!
