Skin exfoliation is the process of removing dead skin cells from the surface of the skin, leaving a fresher, smoother complexion underneath. Protheragen-ING offers a comprehensive cosmetic exfoliation efficacy testing service designed to evaluate the effectiveness of a wide range of cosmetic exfoliation products and techniques.
Whether you are a skincare brand looking to validate product claims or an individual seeking personalized advice, our comprehensive testing services can provide you with valuable insights.
Exfoliation Methods
Hundreds of millions of skin cells are naturally shed every day. When the natural metabolic process slows down or stops, skin conditions such as clogged pores and acne can occur. The use of exfoliating cosmetic products can help the skin to regain a balanced metabolism.
Protheragen-ING is aware of a number of exfoliation methods that can help us to better evaluate the exfoliating effect of cosmetics.
- Mechanical Exfoliation - This method involves physically rubbing the skin to remove dead cells. The common ingredients are mainly various types of scrub granules, including sugar granules, salt granules, natural materials and plastic granules. The exfoliating effect is mainly related to the size, shape and roughness of the granules.
- Chemical Exfoliation - This method involves the use of chemical compounds such as alpha hydroxy acids (AHA), beta hydroxy acids (BHA) or enzymes to dissolve or loosen the bonds between dead skin cells. The addition of acids to cosmetics is subject to strict usage restrictions and technical requirements
- Bio-exfoliation - Bio exfoliants are enzymes that hydrolyze the alpha-keratin in human epidermal keratin, dissolving and removing the excess keratin. Its effect is relatively weak, but it is the mildest.
Protheragen-ING's Testing Services
Our customized testing protocols are tailored to specific needs, analyzing sample ingredients, formulations, and usage for potential benefits and drawbacks. Our state-of-the-art facility is equipped with advanced measurement tools and monitoring systems to capture data on a variety of skin parameters, including assessment of skin texture, skin tone, hydration levels, sebum production, and other specific skin concerns.
Upon completion of testing, we will analyze the evaluation data and provide a comprehensive report summarizing the findings, including statistical analysis and a visual representation of the results.
Our detailed report will help you make an informed decision about the efficacy of your cosmetic exfoliator or guide you in choosing the most appropriate option for your skincare routine.
Evaluation Methodology
Our testing methods are mainly categorized into two types: human testing and laboratory testing.
Human Experiments
(keratin Renewal) |
Stratum corneum renewal time |
The exfoliating efficacy of the product was evaluated by staining the skin with a fluorescent dye, applying the exfoliating sample at a fixed time frequency, and measuring the color recovery of the original skin color at each site using a colorimeter. |
| Dermoscopic Observation Method |
This method uses surface-based microscopy to study the effect of exfoliating products on the number of epithelial scales on the skin to evaluate the exfoliating efficacy of the product. |
Laboratory Experiments
(Keratin Shedding Dimension) |
Shedding Protein Quantification
(BCA Method) |
Since the number of exfoliated keratinocytes is directly proportional to the number of exfoliated proteins, the quantification of exfoliated proteins can be used to evaluate the presence or absence of exfoliating efficacy of a product and the strength of the exfoliating efficacy. |
| Cell Counting Method |
This method evaluates the exfoliating efficacy of an exfoliating product by counting the number of exfoliated keratinocytes after use, usually based on isolated skin tissue. |
| Histologic Observation |
This method is based on ex vivo skin. Tissue-embedded sections and H&E staining of areas other than the control group are compared at different time points to evaluate the exfoliating efficacy of the product. |
