They say that not all that glitters is gold, and not all gold is good for you. A new study published in the journal Nanotoxicology finds that gold nanoparticles accelerate the aging process and can cause wrinkles to appear.
This may not seem like such a big deal, except that little bits of gold are often added to personal care products, which are then applied to the face to give a glittering appearance.
What's more, the gold particles were found to inhibit fat storage, slow healing from wounds and influence the onset of diabetes, according to the team of researchers from Stony Brook University.
Understanding the study
The scientists tested very low doses of gold nanoparticles against various types of cells, finding that in some cases, the gold particles penetrated adult stem cells "almost instantly," and once inside, had no way to get out. These particles caused certain issues within the cells, limiting their movement and preventing cell division and collagen contraction.
"We have learned that careful consideration and the choice of size, concentration and the duration of the clinical application of gold nanoparticles is warranted," said one of the study's authors. "The good news is that when the nanoparticles were removed, normal functions were eventually restored."
What you can learn
This study is another reminder that individuals who purchase skincare and beauty products must conduct thorough research and always read ingredient lists before buying. If over-the-counter beauty treatments seem too risky, you may want to consider opting for a time-tested medical option, such as Botox injections. Aesthetic treatments like Botox can help reduce or prevent wrinkles, resulting in a more youthful appearance. These injectable cosmetics have been tested and approved by the Food and Drug Administration, and, when administered by board-certified plastic surgeons, they carry very few risks and side effects.
