Abstract(s)
A Aloe vera é uma planta extensamente utilizada devido às suas propriedades terapêuticas e cosméticas, como ação anti-inflamatória, cicatrizante, antioxidante e hidratante. A crescente procura por produtos naturais na indústria de cosméticos e suplementos alimentares justifica o interesse por esta planta. Este trabalho teve como objetivo explorar as propriedades benéficas da Aloe vera na cosmética e nos suplementos alimentares, com especial foco na sua eficácia, segurança e possíveis efeitos adversos. Foi realizada uma revisão narrativa da literatura utilizando as bases de dados PubMed, Science Direct, B-ON e Google Académico. A pesquisa incluiu estudos publicados entre 2007 e 2024, selecionados com base na sua relevância para as propriedades e aplicações da Aloe vera em cosméticos e suplementos alimentares. Os estudos analisados confirmaram que a Aloe vera tem um impacto positivo na hidratação, elasticidade e regeneração da pele, sendo eficaz no tratamento de acne, psoríase e queimaduras. Além disso, a Aloe vera apresenta efeitos benéficos no aumento da biodisponibilidade de certos compostos, como as vitaminas C e E, e atua como um complemento terapêutico em doenças inflamatórias crónicas, como a artrite reumatoide. No entanto, foram identificados alguns efeitos adversos, como a hepatotoxicidade e as interações medicamentosas, principalmente em casos de ingestão prolongada ou uso inadequado. Concluindo, a Aloe vera destaca-se como um ingrediente de grande valor na cosmética e nos suplementos alimentares em virtude das suas propriedades regenerativas e hidratantes. Não obstante, o seu uso prolongado deve ser monitorizado para evitar efeitos adversos. A segurança e a qualidade dos produtos devem ser asseguradas através de regulamentações rigorosas.
Aloe vera is a plant widely used due to its therapeutic and cosmetic properties, such as anti-inflammatory, healing, antioxidant and moisturizing properties. The growing demand for natural products in the cosmetics and food supplements industry justifies the interest in this plant. This work aimed to explore the beneficial properties of Aloe vera in cosmetics and food supplements, with a special focus on its effectiveness, safety and possible adverse effects. A narrative review of the literature was carried out using the PubMed, Science Direct, B-ON and Google Scholar databases. The research included studies published between 2007 and 2024, selected based on their relevance to the properties and applications of Aloe vera in cosmetics and food supplements. The studies analyzed confirmed that Aloe vera has a positive impact on skin hydration, elasticity and regeneration, being effective in treating acne, psoriasis and burns. Furthermore, Aloe vera has beneficial effects in increasing the bioavailability of certain compounds, such as vitamins C and E, and acts as a therapeutic complement in chronic inflammatory diseases, such as rheumatoid arthritis. However, some adverse effects have been identified, such as hepatotoxicity and drug interactions, especially in cases of prolonged ingestion or inappropriate use. In conclusion, Aloe vera stands out as a highly valued ingredient in cosmetics and food supplements due to its regenerative and moisturizing properties. However, its prolonged use must be monitored to avoid adverse effects. Product safety and quality must be ensured through strict regulations.
