Dr Dominique Fagot has unveiled the powerful synergy between Nature & Science. After 100 in-vitro tests of duo of ingredients, he was able to select the perfect matches to target each skin concern.

“We rely on this the synergy between active ingredients and skin essential elements for the most effective results.”

Dr Flament analyzed thousands of women living in an urban environment to study the impact of pollution, UV and fatigue on skin.

“Overall, urban skin is affected by both environmental and lifestyle factors: air quality, UV rays, urban pollution, stress and fatigue, tiring activities like public transport and a long daily commute, diet, smoking, and more all affect the speed and extent of the skin's ageing.”

She conducted an exclusive study on women with irregular work/rest periods that proved for the 1st time that an unbalanced lifestyle slows down skin regeneration.

“We now have proof that the lifestyle of urban women has a direct impact on the biology of their skin cells. This study provides, for the first time in human, evidence that in vivo deregulation of the body clock affects regenerative properties of skin cells.”

“I'm in contact with women everyday and I could tell how their fast life affects their skin. Women don't talk anymore about aging signs, but about how their intense lifestyle shows on their skin. Indeed, living fast overworks your body, and then overworks your skin. Skin is then less able to defend itself against urban agressors.”
