Skin vitality index
In order to measure the new Orchidée Impériale Cream's efficacy, Guerlain has developed an unprecedented skin Vitality Index based on an observation made by a dermatologist on 216 women, aged between 20 and 60 years old. This index combines the criteria that reflect the skin’s appearance of youthfulness and vitality (firmness, density, radiance, evenness of the complexion, appearance of wrinkles and fine lines and skin elasticity).

An index value was measured and attributed to each age range: after two months’ treatment, skin recovers the vitality of skin that looks 10 years younger*.

* Average gain – Clinical evaluation by a dermatologist performed on a sample of 41 women, results after eight weeks’ twice-daily application.
