P0178 The impact of fragrance on the perceived efficacy of a cosmetic product A. Dzwigałowska 1, J. Szpanka 1, K. Bazela 1, I. Eris 1 1 Dr Irena Eris Cosmetic Laboratories, Dr Irena Eris Centre for Science and Research, Warsaw, Poland Introduction & Objective Every day our nose is exposed to lots of odours. This smell organ is able to distinguish between thousands of fragrances, and most of olfactory receptors are directly connected to the brain. The sense of smell is located in the brain close to the amygdala, an area responsible for emotions, so beautiful fragrances make us see the world in bright colors, influence well-being and improve the mood. The aim of this study was to evaluate the role of smell in the subjective assessment of the effectiveness of a cosmetic product. Materials & Methods The study was conducted on 105 volunteers, aged 20 to 65 years old. All subjects were using four face creams (A, B, C, D) for 2 weeks each, twice a day. The creams were made on the same base and the components differed only in perfumes (A -odourless, B - selective fragrance, C - pharmaceutical fragrance, D- powdery fragrance). At the end of the study all subjects performed a self-assessment of fragrance and described the effects of the cosmetic treatments. Figure 1.

Effects of 2-weeks application of creams In the self-assessment survey. Results (1) The evaluations of the cosmetic features for the creams with different fragrances varied (A- 3,7, B-4,0, C-4,1, D- 4,0- Fig.1). During 14 days of treatment the volunteers observed improvement in different skin properties: skin moisturization (A-70% volunteers, B-81% volunteers, C-72% volunteers, D-77% volunteers- Fig. 2) and sebum secretion (A-39% volunteers, B-40% volunteers, C-44% volunteers, D-42% volunteers - Fig. 2). Smoothing effect (A-59% volunteers, B-63% volunteers, C-65% volunteers, D-58% volunteers - Fig. 2) and increase in elasticity (A-47% volunteers, B-46% volunteers, C-47% volunteers, D-54% volunteers - Fig. 2) were observed as well. Volunteers were also highly satisfied with the effects of all creams applications (A- 69% satisfaction, B- 73% satisfaction, C- 71% satisfaction, D- 75% satisfaction- Fig.4). The tolerability of each cream was very good. Daily cream application was described as a great pleasure by the volunteers.

Results (2) A smell of cream A was rated lowest of the five point scale (3,7)-Fig.1. Improvement of the overall condition of skin after cream A (odorless) was judged lower (54%) than for the rest of the tested creams (57%,- B, 57%- C, D- 58%) – Fig.3. Similarly the quality of cream A was note d as the worst one (Fig.5). In volunteers opinion a cream C fragrance (pharmaceutical) was the nicest (Fig.1), but its quality (Fig.5) and satisfaction level (Fig.4) were determined in the middle of tested creams. Conclusions Our study showed that the tested formula (Cream A, B, C, D) containing active ingredients such as babassu oil, natural plant extracts (lime, malva) and hyaluronic acid improves the condition of dry and wrinkled skin, but perceptions of the effectiveness of the product may strongly depend on the type of the fragrance.
