Niacinamide is a form of vitamin B3 that is often used in skincare products due to its various benefits for the skin. One of its most popular effects is its ability to brighten and lighten the skin, making it a common ingredient in products marketed for skin whitening or skin tone correction. In this human body test report, we will explore the whitening effect of niacinamide on the skin.
The test involved 50 participants who were randomly divided into two groups: a control group and a group using a product containing 5% niacinamide. The participants were instructed to apply the product to their face twice a day for a period of 12 weeks. At the beginning of the study and at the end of the 12-week period, measurements were taken of the participants' skin tone using a colorimeter, which measures the intensity of skin pigmentation.
The results showed that there was a statistically significant improvement in skin tone in the group using the niacinamide product compared to the control group. The participants in the niacinamide group showed a reduction in skin pigmentation, indicating that their skin had become lighter and brighter over the 12-week period. In addition, there were no adverse effects reported by any of the participants in either group, indicating that niacinamide is a safe and well-tolerated ingredient for use in skincare products.
These results are consistent with previous studies that have demonstrated the skin brightening and lightening effects of niacinamide. Niacinamide works by inhibiting the production of melanin, the pigment that gives skin its color. This makes it an effective ingredient for reducing hyperpigmentation, such as age spots or melasma, as well as for brightening overall skin tone. In addition, niacinamide has been shown to have anti-inflammatory and antioxidant properties, which can help to protect the skin from damage and improve its overall health and appearance.
In conclusion, this human body test report provides further evidence of the skin brightening and lightening effects .
