The aim of the current diploma thesis was to examine the relationship between the composition and the prices of anti-ageing facial creams which are currently available from Slovene pharmacies and specialised and online shops. In order to indentify the most frequently-selected active anti-aging ingredients and the underlying mechanisms of their action we randomly selected 92 facial creams and classified the latter into four price brackets. We also determined the types of the selected secondary active ingredients and auxiliary substances, which significantly influence facial cream quality. The most frequently-selected ingredients were presented in tables and then examined within the predetermined price brackets.
