Assessing the Effectiveness and Success Rate of Skin Care Face Mask


A skincare company introduced a new face mask product claiming to provide various skin benefits, including hydration, deep cleansing, and improved skin texture. The goal of this case study is to evaluate the effectiveness and success rate of the new mask for face through user feedback and dermatological assessments. 



Fifty individuals with diverse skin types (normal, oily, combination, and dry) were selected for the study. They were between the ages of 25 and 45 and had no major skin conditions.


Participants were instructed to use the face mask as directed, which involved applying a thin layer to cleansed skin, leaving it on for 15-20 minutes, and then rinsing off with warm water. They were asked to use the face mask twice a week for four weeks. 

Assessment Measures:

User Feedback Surveys:

Participants were given weekly feedback surveys to record their perceptions of the face mask’s effects. They rated factors like hydration, pore size reduction, and overall skin improvement on a scale of 1 to 5.

Dermatological Evaluations:

At the end of the four-week period, dermatologists conducted assessments on a subgroup of 20 participants. They used tools such as hydration measurement devices, skin texture analysis, and visual inspections to evaluate the skin’s condition before and after the trial.


User Feedback Surveys:

The average ratings for different parameters improved over the four weeks:

  • Hydration: Initial average rating – 2.5 / Final average rating – 4.2
  • Pore Size Reduction: Initial average rating – 2.0 / Final average rating – 3.9
  • Overall Skin Improvement: Initial average rating – 2.7 / Final average rating – 4.3
  • The survey responses indicated that a significant majority of participants noticed positive changes in their skin’s hydration, texture, and overall appearance.

Dermatological Evaluations:

The dermatological assessments revealed consistent improvements in skin hydration levels, especially among participants with dry and combination skin types. Pore size reduction was also observable, though the changes were more subtle. Skin texture analysis showed smoother skin surfaces and a reduction in roughness for most participants.


The case study demonstrated the effectiveness and success rate of the skincare company’s new mask for face product. User feedback indicated a considerable improvement in skin hydration, pore size reduction, and overall skin appearance. Dermatological evaluations supported these findings, showing enhanced skin hydration and smoother textures.

This case study highlights the potential benefits of the face mask and its positive impact on participants’ skin health. The positive feedback and dermatological assessments provide strong evidence for the product’s effectiveness and suggest a high success rate among users.
