Abstract

Ayurveda, the ancient Indian medicinal system, offers a holistic approach to skincare by integrating body, mind, and spirit. This study explores the Ayurvedic perspective on skin health, focusing on the concept of "Twak," which refers to the seven layers of skin, and their role in maintaining skin barrier integrity. Ayurvedic principles such as Varnya (skin brightening) and Shothahara (anti-inflammatory) highlight the therapeutic potential of herbs and natural remedies for skin care. The pH balance of the stratum corneum (SC) is crucial for skin barrier function and hydration, with disruptions linked to various dermatological conditions. This study reviews the pH levels and skin benefits of selected Ayurvedic drugs, including Aloe vera, Papaya, Turmeric, Amla, Neem, Ginkgo biloba, Licorice, and Tulsi. These substances demonstrate potential in maintaining SC pH, supporting the skin's acid mantle, and preventing pathogenic colonization. Aloe vera gel maintains a pH range of 4.5 to 5.5, promoting skin health, while neem products exhibit a pH range of 4.67 to 5.01, aligning with the skin's natural acidic environment. Papaya's pH (4.2 to 5.65) supports the skin's acid mantle and enzyme activity. Turmeric remains stable in acidic environments (pH 1-7), offering anti-inflammatory and antioxidant benefits. Amla's slightly acidic pH enhances skin barrier function and hydration. Ginkgo biloba extracts (pH 5.5 to 6.5) improve skin texture and rejuvenation. Licorice root extract (pH 4.55 to 4.63) exhibits anti-inflammatory, skin whitening, and antioxidant properties. Tulsi-based products maintain a pH compatible with human skin, providing antimicrobial and anti-inflammatory benefits. The study concludes that integrating Ayurvedic practices with contemporary dermatological insights may offer effective, holistic solutions for maintaining skin health and barrier function.
