1. Evaluation of ingredients
2. Stability testing
3. Microbiological testing
4. Instrumental testing
• The SkinChip - A device that is derived from instruments that take digital prints. Measures the skin's hydration. In little more than ten seconds, it captures precise images of the skin to recreate its exact microrelief in a HD image. This map of the skin evaluates its degree of moisturisation and thus measures the effectiveness of a cream.
• The "chromasphere" - This instrument is patented by L’Oréal and analyses the colour of the skin. A map of all the different skin colours in the world has been created (66 tones in total)
• Measure wrinkle structure - This system takes various details about the geometry of wrinkles (depth, width, length) and compares them with the measurements at 28 days after starting to use the product. This is the simplest way of proving that an anti-ageing product is effective.
But that’s not all. After these preliminary tests, additional tests are often carried out by independent laboratories to confirm the initial results to ensure that only the best skincare and makeup products make it to your homes.
