Alliagel®: a technology that is revolutionising cosmetics

Innovation often involves going off the beaten path. That’s exactly what the teams did to formulate combinations of ingredients with antinomic properties. They discovered the conditions necessary for gels thought to be incompatible to blend together. This led to the birth of the exclusive Alliagel® technology, which has several advantages: a new sensory signature, improved availability of active ingredients, and in some cases, dramatic optical results. This technology, which can be adapted to almost all product categories (skincare, makeup, haircare, etc.), reveals how product development can play an integral role in enhancing product performance for the end consumer.


100 years of experience developing safe products

Ensuring the quality and safety of all L’Oréal products for all consumers has been a priority for the Group for over 100 years. This guarantee relies on a rigorous system which encompasses every aspect of our production process worldwide, from the choice of ingredients to product formulation, from manufacturing to compliance with market regulations.

A made-to-order serum

Following in the footsteps of Teint Particulier by Lancôme last year, SkinCeuticals has begun offering personalised products with the D.O.S.E. system, now available in the United States. Based on the expert advice of a dermatologist, or a questionnaire that determines the patient’s skin type, the machine recommends a formula suited to the patient’s skin. The mixer prepares the serum and prints a personalised label with the customer’s name, formula type, application instructions and expiry date.
