Research Summary: The skin, being the largest organ in the human body, plays a pivotal role in safeguarding the body against invasive pathogens. Therefore, it is essential to reinforce and protect this vital organ. Current research supports the impact of probiotics on skin health and their ability to alleviate various skin disorders. However, the effectiveness and potential side effects of probiotics in skincare remain a subject of debate, necessitating further investigation and analysis. This study aims to highlight existing gaps and future needs in the current research on probiotics in skincare, paving the way for future investigations.We examined the effects...

Research Summary: Stem cells are precursor cells present in many tissues with the ability to differentiate into various types of cells. This interesting property of plasticity can have therapeutic implications, and there has been substantial research in this field over the last few decades. As a result, stem cell therapy is now used as a therapeutic modality in many conditions, and it has made its way into dermatology as well. Stem cells can be classified based on their source and differentiating capacity. In the skin, they are present in the inter-follicular epidermis, hair follicle, dermis, and adipose tissue, helping to...

Research Summary: Skin reflects origin, lifestyle, age, and state of health. Skin color, tone and evenness, pigmentation, as well as skin surface characteristics, are signs of skin health. The cosmetic and pharmaceutical industries offer a vast armamentarium of skin care products and procedures to clean, soothe, restore, reinforce, protect, and treat our skin, helping to keep it in good condition. Skin care products are readily available in daily life and play a major role in health and nursing care.The promotion of skin care products, including their claims, is often based on an effect (e.g., moisturizing, antioxidant), evoked by an active...

Research Summary: Retinoic acid (RA) is the biologically active metabolite of vitamin A. It is a low molecular weight, lipophilic molecule that acts on the nucleus to induce gene transcription. In amphibians and mammals, it induces the regeneration of several tissues and organs, and these examples are reviewed here. RA induces the "super-regeneration" of organs that can already regenerate, such as the urodele amphibian limb, by respecifying positional information in the limb. In organs that cannot normally regenerate, such as the adult mammalian lung, RA induces the complete regeneration of alveoli that have been destroyed by various noxious treatments. In...
