The Non Comedogenicity Test is a clinical and photographic evaluation designed to determine whether a cosmetic product clogs pores or contributes to the formation of comedones (blackheads and whiteheads). This test provides objective visual and dermatological evidence of skin compatibility and is essential for products marketed as “non-comedogenic” or suitable for acne-prone skin.

Purpose of the Test

The goal of this test is to verify that a cosmetic product does not obstruct pores or induce comedone formation after regular use. It supports product claims such as “non-comedogenic,” “does not clog pores,” “suitable for acne-prone skin,” and “dermatologically tested for purity.”

How the Test Works

The Non Comedogenicity Test is conducted using an Apparatus Test with standardized before-and-after skin photography. High-resolution images of chosen skin areas (commonly on the face, back, or chest) are taken under consistent lighting and positioning conditions. After a defined period of product use, new photographs are captured and analyzed for visible signs of clogged pores or comedone formation.

Applications in Cosmetic Testing

• Verification of non-comedogenic claims for skincare and makeup products
• Assessment of formulations for acne-prone or oily skin
• Testing of facial creams, foundations, serums, and sunscreens
• Support for “dermatologically tested” and “gentle on skin” claims
• Evaluation of skin tolerance and surface condition after use

Test Procedure

1. The study includes 10 volunteers with normal to acne-prone skin types.
2. Baseline images of selected skin areas are taken before product application.
3. Participants use the product regularly for a defined treatment period (e.g., 4–8 weeks).
4. After the test period, new high-resolution images are taken under identical conditions.
5. Dermatologists evaluate the images to identify any visible changes in pore condition or comedone presence.

Results & Reporting

The final report includes:

• Detailed study protocol and test methodology
• Before-and-after photographs of the tested skin areas
• Dermatological evaluation of comedone presence and pore condition
• Statistical summary of findings and non-comedogenicity classification
• Interpretation of results confirming product tolerance and pore compatibility

Why This Test Matters

Consumers with oily or acne-prone skin often seek assurance that a cosmetic product will not cause breakouts. The Non Comedogenicity Test provides scientific and visual proof that a formulation is safe for daily use without blocking pores, helping brands build trust and substantiate gentle, skin-friendly claims.

Sample Requirements

• Minimum quantity: 50–100 mL or g of finished product
• Number of samples: 11 finished products

Compliance & Standards

The Non Comedogenicity Test is conducted according to in-house methodology I06/PO-08 and in compliance with Good Clinical Practice (GCP) and international cosmetic testing standards. All evaluations are performed by trained dermatologists in a controlled environment to ensure reliable, reproducible, and ethical results.
