Skin Exfoliation Test

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.

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.
