Olowabi JO, et al. (2020). Effects of skin lightening cream agents – Hydroquinone and kojic acid, on the skin of adult female experimental rats. This soap is good for targeting age spots, underarms, inward thighs, and even private parts. It even helps to remove tanning from the arms and feet. The soap helps you peel away dead skin and reveal a lighter complexion over time. Poole, L.B. The basics of thiols and cysteines in redox biology and chemistry. Free Radic. Biol.

Main Benefits: Inhibits an enzyme necessary to produce melanin, helping to fade dark spots and discoloration. It also delivers some antioxidant protection.

[ Google Scholar] [ CrossRef] One thing to keep in mind is that if you use it twice a day, the bar won’t last for an entire week. To keep your soap from getting wet and dissolving, you should store it in a dry place with plenty of air circulation. I also wish the bars were larger. The current size feels too small for my liking.

One thing that sets this soap apart from others is that it lasts a lot longer compared to other glutathione soaps I have tested. It doesn’t melt away like other kojic soap brands either, which is a nice bonus.Boo, Y.C.

Treat melasma: Kojic acid may also be helpful in decreasing melasma, which is darkening of the skin due to pregnancy. Perez-Bernal, A.; Munoz-Perez, M.A.; Camacho, F.

[ Google Scholar] [ CrossRef]TYR oxidizes pyrocatechol to ortho-quinone, and when thiol compounds are present, a pyrocatechol-cysteine conjugate is generated [ 89]. Many studies have used colorimetric methods monitoring the production of dopachrome from tyrosine or DOPA to measure the activity of TYR. Therefore, it is difficult to distinguish whether the test substance directly inhibits the catalytic activity of the enzyme to prevent the production of DQ, or traps the reaction product, DQ, to prevent its oxidation to dopachrome. For most thiol compounds, it is considered that the latter action takes precedence over the former action. With this point in mind, we here discuss the studies reporting the inhibitory effects of various thiol compounds on the TYR-catalyzed reaction.

However, if you’re looking for a soap that can help lighten scars and improve discoloration, this one is definitely worth trying out. Just be prepared to use it consistently and follow up with a good moisturizer to keep your skin hydrated. 4. Kozicare Skin Lightening Soap with Glutathione
