Natural Ingredients in Skincare: A Scoping Review of Efficacy and Benefits

Abstract

The search for safe, durable and effective skincare products has increased the popularity of natural products. Traditional skin care practices across cultures use plant, mineral and animal derivatives believed to provide benefits such as moisturising, anti-ageing, anti-inflammatory and soothing effects. However, with the abundance of skincare products claiming to contain natural ingredients, it is crucial to evaluate the scientific evidence supporting their efficacy and benefits critically. This scoping review aims to comprehensively review the effectiveness and benefits of natural skin care products. This study attempts to explain the impact of existing literature results and the collection of skin health attributes, such as hydration, elasticity, wrinkles, pigmentation, and overall skin appearance. A rigorous search of the databases will identify relevant searches, followed by quality assessment and data extraction. After thorough quality assessments and data extraction, we found many natural ingredients, from botanical extracts to essential oils, demonstrate promising effects on skin health. Notable findings include the potential to be used as a sunscreen agent and antioxidant properties of Violaodorata (sweet violet) flower extracts, the potential cosmetic applications of Hypericum species, and the effectiveness of fermented jasmine rice in promoting skin health. In conclusion, this review aims to comprehensively examine the scientific evidence on skin's natural properties.
