Skincare Clinical Trial Boasts Bright Results
Bright-eyed and bushy-tailed is how the saying goes. But it’s not just your eyes that could use an awakening. Your complexion can benefit from a pick-me-up too.
In a 2020 skincare clinical trial sponsored by USANA, researchers discovered beautiful, bright results with the Celavive Vivid White Sheet Mask, Light Complexion Serum, Dark Spot Corrector, and Luminous Moisture Cream. When used as directed for the duration of the skincare trial, the participants in this study saw visible radiant changes and the appearance of glowing improvements to their skin.
Glowing skin is in, now more than ever. And radiant skin starts with powerful and effective skincare. Look no further than the products in the Celavive Brightening line to achieve a vibrant complexion and a rejuvenated, refreshed look.
See for yourself why the women in this skincare clinical trial raved about their results.
Summary of Brightening Skincare Clinical Trial
- This single-center clinical trial assessed the effectiveness of the Celavive brightening skincare products, including: Vivid White Sheet Mask, Light Complexion Serum, Dark Spot Corrector, and Luminous Moisture Cream.
- The trial was conducted by Thomas J. Stephens at the SGS Stevens Dallas Research Center—an independent research center.
- The participants in this study were 29 women between the ages of 36 and 65 (average age was 53.4 years) of differing ethnicities.
- Each participant had mild-to-moderate hyperpigmentation and uneven skin tone, with at least one dark spot (age spot) on their face.
- The women in this study received a Celavive skincare regimen suited for their skin type—including the brightening products—to use twice daily for 12 weeks.
- Participants saw significant improvements to the appearance of dark spots and hyperpigmentation. Skin was brighter and more radiant after the 12-week treatment.
- The products are safe to use.
From early on in the clinical trial, women noticed remarkable changes to their age spots and uneven pigmentation. All participants in the study reported improved visible brightness and glowing skin after using the brightening treatment products.
Brightening Skincare Trial Design
A group of 29 women participated in the clinical trial of the Celavive Brightening product line. As mentioned above, the women in the study varied in age and skin type.
Before Brightening Treatment
At the beginning of the skincare trial, the women completed a series of baseline evaluations to measure the tone and evenness of their skin, as well as the intensity of darker age spots. Digital images of each woman’s face were captured with a VISIA CR photo station and Canon Mark II digital SLR camera. These images were cataloged for comparison throughout the 12-week study.
In addition to photographs, Chroma Meter™ measurements were taken from each subject’s face, specifically at their targeted dark spots. The Chroma Meter evaluates the intensity of hyperpigmentation marks, and its measurements can be compared over time to assess the change in dark-spot intensity.
Product performance surveys, self-response questionnaires, and tolerability evaluations were also administered to the women in the study. Participants used these surveys to record how they felt about the quality and efficacy of each product throughout the trial.
Skincare Trial Procedure
After imaging and baseline measurements were taken, the clinical trial participants received a regimen of Celavive skincare products to be used twice daily (morning and night). In addition to the makeup remover, cleanser, toner, and lotion/cream, the women were given the entire line of brightening products:
- Vivid White Sheet Mask
- Light Complexion Serum
- Dark Spot Corrector
- Luminous Moisture Cream
Here is an example of the regimens followed by each participant. Light Complexion Serum and Luminous Moisture Cream were applied all over the face. Dark Spot Corrector was applied to targeted areas only. And Vivid White Sheet Masks were used on an incremental basis—first once a week, then twice, and ultimately three-times weekly.

Researchers collected the responses to the performance and tolerability surveys at the four-, eight-, and 12-week marks. Updated Chroma Meter evaluations and VISIA images of each participant were also taken at the four-, eight-, and 12-week intervals.
Visibly Glowing Responses to Brightening Regimen
USANA is happy to report that the participants in this study responded favorably to the brightening products and Celavive skincare regimen. Overall, there was a significant reduction in intensity of dark age spots, and an increase in the appearance of radiance and glow of the participants’ skin.
Clinical Grading Parameters
The clinical grading of efficacy parameters showed a statistically significant improvement in intensity (visual) of the targeted dark spot, and radiance and skin tone evenness on the global face at weeks 4, 8, and 12; and in hyperpigmentation (mottled and/or discrete) and overall skin appearance (healthy glow) on the global face at weeks 8 and 12 when compared with baseline.
4-, 8-, and 12-Week Subject Percent Improvement from Baseline on Clinical Grading Parameters
The Chroma Meter values and VISIA images obtained during the study showed remarkable changes in discoloration over the 12-week trial period. Significant improvements to the overall appearance of the skin were noted, as well.
Self-assessment of Benefits
Clinical trial participants helped assess the benefits of the brightening products. Their opinions were recorded and compared across the life of the study. Significantly more trial participants saw improvements from their baseline values at the beginning of the study.
