Multiple benefits proven in vivo for Chinese skin To investigate the beauty complex’s potential to deliver a further range of skin care benefits, 66 Chinese females, age 35 and 60, took part in a single-blind, randomised, placebo-controlled study. Volunteers applied either an active formulation with 3% of the beauty complex or a placebo formulation to the whole face and neck area twice daily for 28 days. A range of measurements were taken from
all volunteers the day before they applied the test formulations (day 0) and then on days one,
14 and 28 after application. Various parameters were assessed including skin texture and smoothness, lines on the forehead, crow’s feet and underneath the eyes, and skin elasticity, firmness and lines on the neck. Participants also completed a qualitative questionnaire two weeks into the study – after 14 days of applying either the active or placebo formulation. For subjects using the formulation with the
3% beauty complex, the results were highly significant compared to the placebo group.
Very fast action Changes in skin smoothness compared to day 0 were assessed at defined sites around the
cheek area using Visia-CR + IPP software. These assessments showed that skin was 16% smoother within one day of applying the active formulation and 23% smoother after four weeks (28 days). Images taken by Visia-CR camera also
showed that the skin was already visibly smoother after one day and that this change was even more pronounced by weeks two and four (Figure 2).
Forehead wrinkles, crow’s feet, and wrinkles underneath the eye reduced significantly in two weeks Changes in the volume and number of crow’s feet, forehead wrinkles and under eye wrinkles compared to day 0 were evaluated by Primos
