Article Synopsis
  • Hyperpigmentation is difficult to manage due to its various causes and existing treatments often have limitations or side effects that make them unsuitable for long-term use.
  • A new gel serum containing ingredients like tranexamic acid and niacinamide was tested to see if it could effectively reduce melanin production and improve skin tone.
  • The study found significant reductions in melanin production and hyperpigmentation after 84 days of use, with improvements in skin luminosity and overall appearance, suggesting the gel serum is a promising treatment option.

Article Synopsis
  • The study explores natural plant ingredients, bakuchiol (BAK) and Vigna aconitifolia extract (VAE), as enhancements to the retinoid retinal (RAL) for anti-aging benefits, with fewer side effects.
  • Methods included gene expression profiling, assessing skin irritation, and a clinical study to test a cosmetic formulation combining these ingredients with others like niacinamide and melatonin.
  • Results showed that the tri-retinoid complex (3RC) significantly improved skin characteristics, such as firmness and elasticity, while reducing wrinkles, with 100% of participants seeing a decrease in crow's feet after 28 days of use.

By gel retardation experiments with crude cell extracts of Paracoccus denitrificans it was demonstrated that a protein specifically binds to the promoter of the P. denitrificans recA gene. PCR mutagenesis of the recA promoter showed that the GAACN7GAAC motif is required for the formation of the DNA-protein complex.
