Below are the results of consumer research studies proving the benefits of Praventin as a blemish treatment on both Asian & Caucasian skin types when consumed daily over a period of 4 to 8 weeks.

 

Consumer research study 1 - test market group

Evaluating Praventin™ as a dietary supplement for the support of a healthy complexion

Forty-four participants, for whom other so called 'acne cures' had proved ineffective, but who shared the desire to be acne free, were enrolled in the study (23 males and 21 females). For 8 weeks the subjects were supplemented with 200mg of Praventin™. Photographs, taken by an independent photographer were blinded and evaluated by a dermatologist.

Subject data were collected at week 0 (baseline), which occurred before supplementation started, as well as at weeks 2, 4, and 8. The number of blackheads (open comedones) and non-blackheads (including whiteheads, closed comedones, papules, pustules and nodulocystic lesions) were counted on the forehead, left cheek, right cheek, chin, and nose. For each subject blackheads and non-blackheads were summed over the facial regions each week.

The graph shows time trends of total blemishes counts for individual subjects (in blue) with the time trend of the medians superimposed (in red).

After stopping Praventin™ supplementation at week 8 the number of blemishes started to increase, as measured by an increased number of blemishes at week 12.

Over 76% of the participants observed visible improvements, including fewer blemishes, a reduction in the amount of redness and less oiliness.

Consumer research study 2 - test market group

Evaluating the effectiveness of Praventin™ in a dietary supplement regimen

Forty-two participants were enrolled in the study and divided into 3 groups. The groups were stratified for gender and baseline acne severity. All groups were supplemented with Praventin™ for 8 successive weeks. Group 1 received a total amount of 25mg Praventin™ per day; Group two received a total amount of 100mg Praventin™ per day; and Group three received a total amount of 200mg Praventin™ per day.

Subjects had front profile photographs taken by an independent photographer. Photographs were blinded and evaluated by a dermatologist. Subject data were reported at week 0 (baseline) and week 8.
