Evaluation of comedogenic potential of a paraben-free plant-based butter moisturizing cream: A double-blind, comparative study

Objectives: Comedogenicity is a critical factor in making of cosmetics and skin care products. The term “acne cosmetica” was coined to link the relationship between female acne to the use of cosmetic formulations, stating that the ingredients used in the cosmetic formulations have the potential to evoke a comedogenic response or produce comedones. Therefore, it is important that a skin care product is non-comedogenic and efficacious at the same time. The main objective of this study is to evaluate the comedogenic potential of the test product (Venusia Max Cream – paraben free) when applied topically under occluded patch to the skin. Material and Methods: This was a randomized, double-blinded, comparative study conducted in 24 healthy female participants, with prominent follicular orifices on the upper back region. Comedogenic potential of the test product (Venusia Max Cream – paraben free) was evaluated in comparison to positive (coconut oil) and negative (glycerin) controls in women. Each participant received topical application of test and control products under occluded patch to the skin on the upper aspect of the back, 3 times weekly for 4 weeks. Cyanoacrylate biopsies were performed before and after treatment to determine the microcomedones histologically. Microcomedones were graded using light microscopy and results were analyzed based on scale rating (0–3). Results: The mean comedone grading was assessed between positive versus negative control, and positive control versus test product. The mean comedone grades were significantly less in test product 0.41 ± 0.50 and negative control 0.82 ± 0.73 in comparison to positive control 2.09 ± 0.68. The test product was least comedogenic in this study. Furthermore, no adverse events were reported during the study period. Conclusion: Based on the histological evidence, Venusia Max Cream (paraben free) is a non-comedogenic, plant-based intense moisturizing cream and its use in regular skin care routine can be beneficial, particularly for acne prone and dry skin as it improves the skin hydration levels.
