PRODUCT TESTING



IN USE TEST

  • Measures the skin acceptability of the cosmetic product.
  • Carried out under appropriate controls: dermatological, paediatric, gynaecological, ophthalmological, odontological, etc.
  • Allows verification of the absence of cumulative adverse reactions or irritation associated with the habitual use of the product.
  • Subjective evaluation of claimed effects by consumers.

Allows claims to be justified.

PATCH TEST

  • Highly recommended for new product launches.
  • Measures the cutaneous compatibility of the product with normal and sensitive skin.
  • Carried out under dermatological control.

For claim: “Dermatologically tested”.

OPEN TEST

  • Highly recommended for new product launches.
  • Measures the cutaneous compatibility of the cosmetic product (dyes, nail varnishes, perfumes, depilatory products).
  • Measures the cutaneous compatibility of the product with normal and sensitive skin.
  • Carried out under dermatological control.

For claim: “Dermatologically tested”.

HRIPT

  • Clinical study of the potential for sensitisation due to contact with the cosmetic product.
  • Measures the cutaneous compatibility of the product after repeated applications.

For claim: “Hypoallergenic”.

HET-CAM

  • Highly recommended for products applied in the eye area and near mucous membranes.
  • In vitro, primary eye irritation test

MICROBIOLOGICAL ANALYSIS

  • All manufacturers must ensure that their products are free, by number and type, of micro-organisms that could affect product quality or consumer safety.
  • Microbiological control of raw materials, loose products, finished products.

CHALLENGE TEST

  • Evaluation of the antimicrobial efficacy of the preservative system used by the cosmetic product following ISO11930.
  • Analysis of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger.
  • Obligatory test, according to the European Commission, except for some products.
  • Evaluation of various pathogens.

HYDRATION EFFICACY

  • Verification of the degree and duration of hydration from a cosmetic product.
  • Measurement of hydration using a Corneometer.
  • Includes subjective evaluation by consumers.

FIRMING EFFICACY

  • Verification of the firming efficacy (tensor and toning effect).
  • Measurement of the tensor or toning effect using a Cutometer (elasticity).
  • Includes subjective evaluation by consumers.

ANTI-AGEING EFFICACY

  • Verification of the anti-ageing efficacy: tensor effect, hydration, reduction of wrinkles.
  • Measurement of elasticity using a Cutometer, of hydration effect using a Corneometer and confirmation of wrinkle reduction using high-definition photographs.
  • Includes subjective evaluation by consumers.

SEBUM REGULATOR

  • Verification of the regulation of sebum secretion
  • Measurement of sebum secretion using a Sebumeter, and of sebaceous glands using MSA pro / Sebutape.
  • Includes subjective evaluation by consumers.

ANTI-DARK CIRCLE EFFICACY

  • Verification of the reduction in dark circles.
  • Visual clinical evaluation by the investigator and visual analogue scales by the volunteer.
  • Includes subjective evaluation by consumers.

ASTRINGENT EFFICACY

  • Verification of the reduction in dilated pores.
  • Visual clinical evaluation by the investigator and visual analogue scales by the volunteer.
  • Includes subjective evaluation by consumers.

DERMO-PROTECTOR EFFICACY

  • Verification of facial skin protection.
  • Evaluation through measurements of barrier function by TEWL (transepidermal water loss), degree of hydration (Corneometer), cutaneous pH, and evaluation of reddening and of skin softness through visual assessment by the investigator.

STABILITY

Short-tern stability study: the evaluation of a cosmetic product under conditions of heat stress over three months. Predicts the theoretical product life.

COMPATIBILITY

Compatibility test: this test must be carried out on the final product and container, as a complement to the stability test, to detect interactions between the container and the product that could change the nature of the the product or compromise the safety of the product.
