The influence of cosmetics dedicated to oily and acne‐prone skin on skin parameters.

Introduction: Patient compliance with care recommendations is closely related to the role of cosmetics in delaying or preventing the side effects of medications used to treat acne. Methods: A total of 33 volunteers with symptoms of acne vulgaris were qualified for the study. The skin parameters were measured before the experiment, after the 4 and at the 8 weeks of use. The measurements were subject to moisturizing the skin and secretion of sebum and skin color. A skin acoustic parameters using high‐frequency ultrasound (33 MHz) was also performed. The recorded images were used to determine the epidermal entrance echo thickness and echo density of dermis. Results: The results show a change in the value of skin parameters during the 8‐week application of a specific skin care procedure. The secretion of sebum did not change significantly, there was a decrease in hydration, and the level of melanin and hemoglobin remained at the same level. The thickness of the epidermis entrance echo in the ultrasound image was thinned. Conclusion: For many mild/moderate acne patients, cosmetics proven to be effective and well tested in clinical trials can offer a real benefit in reducing both inflammation, sebum production, melanin, and irritation, but should also be moisturizing.
