Summary
Shikimic acid (SA), found in star anise, is a cosmetic ingredient with antiviral, exfoliating, and anti-aging properties. It offers benefits like acne reduction and moisturization, with a 5% concentration comparable to glycolic acid for exfoliation.
Area of Science:
- Cosmetic Science
- Natural Product Chemistry
Background:
- Shikimic acid (SA), primarily used in pharmaceuticals, is emerging in cosmetic applications.
- Research on SA in cosmetics, particularly human subject testing, is limited.
- Star anise is the main natural source of SA.
Purpose of the Study:
- To review the properties and potential applications of Shikimic acid in cosmetic formulations.
- To highlight the efficacy of SA as a cosmetic ingredient.
Main Methods:
- Literature review of Shikimic acid's properties and reported effects.
- Analysis of SA concentration and pH in cosmetic preparations.
- Comparison of SA's exfoliative effect with glycolic acid.
Main Results:
- Recommended SA concentration in cosmetics is 1-5%.
- A 5% SA solution has a pH of 3 and comparable exfoliative effects to 50% glycolic acid.
- SA exhibits antiviral, exfoliating, anti-acne, anti-dandruff, whitening, moisturizing, sebum-regulating, antibacterial, anti-inflammatory, hair-growth stimulating, anti-aging, and antifungal activities.
Conclusions:
- Shikimic acid possesses a wide range of beneficial properties for cosmetic use.
- SA is a promising ingredient for anti-aging, acne control, and skin conditioning products.
- Further research, including clinical studies, is warranted to fully explore SA's cosmetic potential.

The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential. It is generated by differences in permeability of the membrane to various ions and the concentrations of these ions across the membrane.

The membrane potential of a cell can be measured by inserting a microelectrode into a cell and comparing the charge to a reference electrode in the extracellular fluid. The...

01:24Non-gated Ion Channels
7.6K
Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....
