    Scientific Evidence for the Cosmetic Skin and Hair Benefits of Hemp-derived Cannabinoids: A Review

    Gregory Luke Smith* and Shannon M. Powell

    DOI: 10.37421/2471-9323.2023.9.226

    Cannabinoids derived from hemp, known as phytocannabinoids, are a group of approximately 120 bioactive compounds found in the Cannabis sativa plant. They have gained increasing attention in recent years, emerging as promising ingredients in the cosmetics industry due to their proven therapeutic and cosmetic benefits for skin and hair. It is worth noting that they do not produce psychoactive effects associated with tetrahydrocannabinol (THC). This paper summarizes the available published in vitro, in vivo and human studies on cosmetic benefits of cannabinoids for hair and skin. Several of the mechanisms of action of cannabinoids are novel and entirely different from all other cosmetic ingredients because they interact with specific receptors in the hair and skin cells to turn “on” or “off” cellular processes. In addition, there are issues related to the formulation, legal requirements and regulatory considerations associated with incorporating cannabinoids into cosmetics formulations as discussed.

      Facial Wrinkles in Asia Treated by Tri Focused Ultrasound: Painless Non-invasive Procedure

      Bernard Murino* and Herny B

      DOI: 10.37421/2471-9323.2023.9.216

      HIFU is a non-invasive cosmetic procedure that uses high-intensity ultrasound waves to target and heat deep tissue layers, stimulating collagen production and tightening the skin. Several studies have evaluated its efficacy and safety in skin tightening for various areas of the face and body, including the crow's feet wrinkles around the eyes.

      One such study published in the journal of cosmetic and laser therapy in 2018 evaluated the efficacy and safety of HIFU for non-invasive skin tightening of crow's feet wrinkles in 20 female participants. The study found that a single session of HIFU resulted in a significant improvement in skin tightness and reduction in wrinkles at 12 weeks post-treatment. Moreover, this improvement was maintained at 24 weeks post-treatment, suggesting that HIFU can provide long-lasting skin tightening effects.

      However, it is important to note that the effectiveness of HIFU may vary depending on the individual's skin condition, age, and other factors, and multiple sessions may be required to achieve optimal results. Additionally, as with any cosmetic procedure, there may be some risks and potential side effects associated with HIFU, including temporary redness, swelling, and tingling sensations.

        Meteors - light from comets and asteroids

        Sean M Davidson

        In studies of the oldest solar system bodies – comets and asteroids – it is their fragments – meteoroids – that provide the most accessible planetary material for detailed laboratory analysis in the form of dust particles or meteorites. Some asteroids and comets were visited by spacecrafts and returned interplanetary samples to Earth, while missions Hayabusa 2 and OSIRIX-REx visiting asteroids Ryugu and Bennu are ongoing. However, the lack of representative samples of comets and asteroids opens the space to gain more knowledge from direct observations of meteoroids. At collision with the Earth’s atmosphere, meteoroids produce light phenomena known as meteors. Different methods can be used to observe meteors, allowing us to study small interplanetary fragments, which would otherwise remain undetected. Numerous impressive meteor showers, storms and meteorite impacts have occurred throughout the recorded history and can now be predicted and analyzed in much more detail. By understanding the dynamics, composition and physical properties of meteoroids, we are able to study the formation history and dynamical evolution of the solar system. This work presents an introduction to meteor astronomy, its fundamental processes and examples of current research topics.

        An Overview of Hair Coloring and its Types

        Shanker Kumar*

        Hair coloration, often known as hair dyeing, is the process of changing one's hair colour. The most common reasons are cosmetic: to hide grey or white hair, to change to a more fashionable or beautiful hue, or to restore the original hair colour after hairdressing or sun bleaching has harmed it. The four most common classifications are permanent, demi-permanent, semi-permanent, and temporary.
