Objectives: This study aims to assess the impact of using a cleanser with a pH value of 4.8, close to the physiological pH of skin, on skin health over an 8-week period. Specifically, it examines changes in skin pH, the time required for skin pH to return to its baseline (recovery time), and observable skin conditions such as redness, Transepidermal Water Loss (TEWL), and pore visibility in a cohort of 86 women and 24 men with Rosacea and average skin pH values of 5.45 and 5.32, respectively.
Introduction: The skin's pH is a critical factor in maintaining its barrier function and overall health. Disruptions to skin pH can lead to various dermatological issues. This study investigates how cleansers with a pH aligned to that of the skin affect its pH balance, recovery time, and other skin health indicators, providing insight into the potential benefits of selecting pH-appropriate skincare products.
Materials / method: Participants included 86 women and 24 men, subjected to an 8-week regimen using a cleanser with a pH of 4.8. Skin pH, TEWL, redness, and pore size were measured at baseline, weekly, and at study completion. Significant changes were anticipated from the second week, with recovery times and participant satisfaction also evaluated.
Results: By the second week, significant improvements were observed: skin pH adjusted to 5.15 in women and 5.2 in men, with further reduction to 4.95 and 5.05, respectively, by the fourth week. Skin redness and TEWL decreased significantly (p-value < 0.001), and pores became less visible. Recovery time dropped dramatically from 105 minutes for women and 98 for men to 35 and 31 minutes, respectively, by the eighth week. Satisfaction increased by 65% among women and 70% among men.
Conclusion: The study conclusively shows that using a cleanser with a pH close to the skin's natural pH significantly improves skin health, as evidenced by reduced recovery times, improved skin conditions, and high levels of participant satisfaction. These findings underscore the importance of choosing skincare products that maintain the skin's natural pH balance, potentially leading to healthier skin and improved dermatological outcomes. Further research is encouraged to explore long-term benefits and effects on various skin types.
