L'arbre national des Émirats pourrait-il détenir le secret d'une peau jeune ?

A team of international researchers has discovered that extracts from the ghaf tree, the national tree of the United Arab Emirates, may offer powerful anti-ageing properties for skincare. The findings suggest that the plant’s natural compounds could be used in commercial products designed to maintain youthful skin. The research, conducted by scientists based in France, Italy, and the Maldives, focused on the chemical composition of the ghaf tree, known scientifically as Prosopis cineraria. Researchers collected samples of twigs, roots, leaves, and bark from ghaf trees growing in the UAE. These materials were processed into a fine powder and subjected to detailed analysis. The results showed that the extracts had exceptionally high activity in neutralizing free radicals, molecules linked to cellular damage and the aging of skin. According to the study, the ghaf tree extracts contain over 20 distinct chemicals, some of which demonstrated greater efficacy than vitamin C, a commonly used anti-ageing ingredient, in combating free radicals. In addition, the extracts were found to inhibit enzymes associated with skin degradation. This combination of effects positions the ghaf extract as a versatile component for use in cosmetic formulations aimed at reducing visible signs of aging. While the researchers have created a stable facial cream prototype, additional testing is required to verify both its safety and effectiveness before it can reach the market. The global natural cosmetics industry is valued at up to $33 billion annually, suggesting that products incorporating ghaf tree extracts could find a receptive audience. The preliminary findings have been shared as a preprint, indicating that the study has not yet undergone peer review by other experts in the field. Nevertheless, the research highlights the potential of the ghaf tree as a novel source of skincare ingredients. The discovery adds to a growing list of UAE-native plants being explored for their medicinal and cosmetic value. For instance, the yusor tree has shown promise in cancer treatment, while mulberry trees may provide compounds with antibiotic properties. Dr. Rakesh Kumar Mishra, a dermatologist at Aster Cedars Hospital and Clinic in Jebel Ali, explained that the harsh environmental conditions in which ghaf trees thrive, such as intense heat and exposure to ultraviolet radiation, may contribute to the production of protective compounds within the plant. These compounds, he noted, are part of the plant’s natural adaptation strategies evolved over millions of years. Despite the encouraging initial results, Dr. Mishra emphasized the need for extensive follow-up research to determine whether the extracts can be effectively incorporated into commercial skincare products. He acknowledged the increasing consumer preference for natural ingredients in anti-ageing treatments, calling the study’s findings promising. Dr. Sherin Mohamed Attalla, a dermatologist at Medcare Hospital Sharjah, Sheikh Saqr Al Qasimi, highlighted the significance of the study’s findings. She pointed out that the ghaf extract appears to target multiple pathways involved in skin aging, offering potential benefits such as improved skin firmness, elasticity, hydration, and radiance. According to her, this multi-target approach aligns well with the goals of modern skincare, which seeks to address various aspects of aging simultaneously. The study underscores the potential of exploring native flora for innovative solutions in the beauty and healthcare industries. As research continues, the ghaf tree may emerge as a key player in the development of next-generation skincare products.
