For more than a century, L’Oréal has devoted itself solely to one businessbeauty. It is a business rich in meaning, as it enables all individuals to express their personalities, gain self-confidence and open up to others. From make-up to hair color, from hair care to skincare and fragrances, our products magnify, beautify, soothe, moisturize, strengthen, rejuvenate... Regardless of a person’s  age, origin or personality, above all and before all, they enable her or him to care for what is certainly most precious to each man and each woman – and most fragile: the face, the skin, the body… in a word: caring for oneself.


Our research budget reached €794 million in 2015, which represents 3.1% of turnover.

In the last 10 years, our Research budget has increased more rapidly than the Group's sales.

More than 490 patents were registered in 2015. Our workforce consists of 3800 employees, representing about sixty nationalities and thirty different scientific backgrounds (chemistry, physics, biology, dermatology, optics, rheology, IT, statistics, analysis, etc.).


The candidate will be responsible for carrying out and for proposing scientific research projects and collaborations based on atomic force microscopy (AFM) on cosmetic substrates such as skin, hair and different cosmetic materials.  He will develop and implement new AFM approaches to quantify the surface properties and the mechanical properties of hair and skin and their constituents in physiological conditions. He will play a supportive role to evaluate in close collaboration with the teams from the biology and chemistry departments the performance of new raw-materials developed for haircare and skincare products.
