Efficiency demonstrated in a randomised, double-blind vs placebo study
A panel of 34 people (Skin phototypes IV and V) has received a 100mg food supplement of Cosmythic® consisting in 2 daily intakes of 50mg during 56 days. The results have been measured by a spectrocolorimeter (Minolta® CM700-d) on the 3 parameters L, a and b.
- Parameter L measures skin lightening (from the darkest to the lightest).
- Parameter a measures the spectrum from the green to the red.
- Parameter b measures the spectrum from the blue to the yellow.
After a 56-day treatment using Cosmythic®, a significant decrease in parameter b, the yellow pigment of the skin (p=0,0147), can be observed.
Skin lightening is dramatically improved after a 56-day treatment (p=0,07) whereas no significant variation can be observed for the placebo group.
Parameter ITA is a skin luminosity indicator. The higher the parameter is, the more the skin pigmentation decreases.
