The invention relates to a method of measuring the elasticity and firmness of skin. The invention also relates to methods of measuring improvements in a person's skin health by measuring firmness and elasticity before, during and after a cosmetic treatment. The invention further relates to methods of measuring the improvement in a person's skin firmness and elasticity that a cosmetic agent may cause when applied on the skin.

Method to measure skin elasticity and firmness

The subject of the present invention is a method for characterizing the distribution of the volumes of the surface of the skin of an individual, more particularly applicable in the evaluation of the effect of firming cosmetic products. This method uses the isolines and the gradients of the slopes computed from a three-dimensional representation of the surface of the skin.

Method for characterising volumes of skin

The invention relates to a method and apparatus for characterizing the tone of the skin or integuments. The apparatus comprises a digital camera or a digital photographic apparatus () allowing the capture of at least one digital image () of at least one determined skin zone (), said image being defined by a multiplicity of pixels (N) that is transmitted to a digital image processing device comprising means for splitting the digital image into three color planes: red, green, blue, termed R, G, B; The invention finds an industrial application in a method for assessing the whitening effect of a cosmetic product.

Method for characterizing the tone of the skin and integuments

The invention relates to a cosmetic composition containing at least one extract from at least one part of the Sacred Lotus plant () in a cosmetically acceptable vehicle compatible with topical application on the skin, wherein said composition contains an aqueous extract of Sacred Lotus root and it additionally contains at least one active agent selected from the group comprising active agents with energizing or revitalizing activity, preferably diguanosine polyphosphate or an extract containing it; active agents stimulating the secretion of beta-endorphins, preferably an N-acetyl-Tyr-Arg-hexadecyl ester dipeptide; anti-radical agents such as tocopherol, and plant extracts containing them as well as flavonoids and anthocyanins and plant extracts containing them, in particular extracts of Sacred Lotus flower and anti-inflammatory agents, in particular those having a phospholipase A2 inhibitory action.
