Evaluation of skin compactness and elasticity
| Regulatory reference: | Guidelines to Commission Regulation (EU) No 655/2013 |
| Claim: | Firming efficacy, Improves skin tone and smoothness and Improves skin elasticity |
| Application field: | Visage and body products. |
| Description of the test: | Measurement of R0 and R2 parameters on 20 healthy volunteers. Instrument: MPA580 Cutometer® for the scientific quantification of the viscoelasticity of the skin. Manufacturer: Courage-Khazaka GmbH (Germany). |
Evaluation of the activation of the synthesis of collagen and fibronectin
| Regulatory reference: | Proprietary method |
| Claim: | Activates the synthesis of collagen, elastin, fibronectin |
| Application field: | Finished products and active ingredients. |
| Description of the test: | Real time PCR analysis of the expression of collagen and fibronectin, compared to an untreated control, to determine the efficacy of a product or ingredient in activating the synthesis of these proteins involved in maintaining skin elasticity and prevent aging. |
Evaluation of the activation of the synthesis of collagen and elastin
| Regulatory reference: | Proprietary method |
