- Acne vulgaris topical therapies: application of probiotics as a new prevention strategyPublication . Dapkevicius, Ieva; Romualdo, Vânia; Marques, Ana Camila; Lopes, Carla Martins; Amaral, Maria HelenaThe skin microbiome is an essential barrier for preventing the invasion of pathogens and regulating the immune responses. When this barrier is disrupted, several dermatoses, including acne vulgaris, may arise. Most people will experience acne starting at the onset of puberty and continuing into adolescence; a significant percentage of those individuals continue to suffer from it into adulthood. Although common, this dermatosis usually has an enormous impact on the self-esteem and quality of life of individuals who suffer from it. An increase in consumer literacy regarding skincare leads buyers to seek out innovative products containing ingredients with proven benefits for their concerns. Probiotics have proven to be an alternative to the use of antibiotics, often associated with undesirable effects, in the treatment and prevention of dermatological disorders such as acne. This review provides a comprehensive analysis of the pathophysiology, risk factors, symptoms, conventional treatment recommendations and main studies emphasizing innovative topical products for acne-prone skin based on probiotics. In addition, the potential advantages, and limitations/challenges associated with the implementation and manufacturing of these innovative skin products are also highlighted.
- Biotechnology applied to cosmetics and aesthetic medicinesPublication . Gomes, Cátia; Silva, Ana Catarina; Marques, Ana Camila; Sousa Lobo, José; Amaral, Maria HelenaBiotechnology uses microorganisms and/or enzymes to obtain specific products through fermentative processes and/or genetic engineering techniques. Examples of these products are active ingredients, such as hyaluronic acid, kojic acid, resveratrol, and some enzymes, which are used in skin anti-aging products. In addition, certain growth factors, algae, stem cells, and peptides have been included in cosmetics and aesthetic medicines. Thus, biotechnology, cosmetics and aesthetic medicines are now closely linked, through the production of high-quality active ingredients, which are more effective and safer. This work describes the most used active ingredients that are produced from biotechnological processes. Although there are a vast number of active ingredients, the number of biotechnological active ingredients reported in the literature is not significantly high.
