Evaluation of effectiveness, post-use assessment of Pure-lyn on 20 subjects over 4 weeks

The report provides a summary of a cosmetic study involving a panel of selected volunteers. The study aimed to evaluate the cosmetic attributes and skin compatibility of the Swiss skincare product Pure-lyn Purifying Water.

Selected Panel

The study included 21 volunteers: 19 women and 2 men. The participants’ average age was 30 ± 6 years. All skin types were represented, with 62% having normal skin and 38% having sensitive skin. Specific selection criteria included subjects with facial imperfections such as papules and comedones, acne, enlarged pores, and those willing to have their photos used for the study.

Self-Assessment and Cosmetic Evaluations

The volunteers were invited to give their opinions on various cosmetic attributes of the product. The product received positive feedback, with high percentages of agreement for attributes such as pleasant fragrance, ease of use, a fresh sensation, and a non-sticky texture. Some participants reported improved skin hydration, suppleness, and softness, as well as reduced redness.

Skin Compatibility and Clinical Reactions

Among the 21 volunteers, 10% experienced skin reactions, such as a slight feeling of tightness, erythema, and dryness. Overall, the product was considered well tolerated (90% of subjects), with good skin compatibility. 75% of the volunteers expressed overall satisfaction with the product. 60% would consider purchasing the product, and 70% would recommend it. The dermatologist noted some mild skin reactions in a few subjects, such as erythema and acneiform dermatoses. In some cases, these reactions were attributed to the product, while in others, this was considered possible.

Results and Conclusions

After 28 days of product use, self-assessment showed a significant 25.4% decrease in imperfections (papules and comedones) compared with day 0 (D0). The product had a positive effect on 85% of the subjects, with a significant reduction in imperfections observed on day 28 (D28). The study concluded that there was a significant improvement in the reduction of imperfections after 28 days of product use. It is important to note that the results mentioned in the report relate only to the specific study and product evaluated and cannot be generalized to other products or populations. Further research and testing may be required for broader conclusions.

Evaluation of effectiveness, VISIA approach after use of Pure-lyn on 20 subjects over 4 weeks

Redness Index:

A significant 6.5% decrease in the redness index was observed on day 28 (D28) compared with day 0 (D0). The product showed a positive effect on 63% of the subjects.

Porphyrin Index:

A significant 14.2% decrease in the porphyrin index was noted on D28 compared with D0. The product demonstrated effectiveness in 70% of the subjects.

Product Claims and Conclusion

The evaluation of Pure-lyn’s effectiveness through self-assessment and the VISIA approach (high-resolution imaging using VISIA-7 technology) showed strong and promising results in reducing imperfections and redness.
