Plain English Summary

Background and study aims
Acne is a common skin condition that affects most people at some point. It causes spots, oily skin and sometimes skin that's hot or painful to touch. The following treatments will be used in the study: carboxytherapy (infusions of carbon dioxide), oxybrasion (exfoliation with oxygen), hydrogen purification (with hydrogen-infused water), and cosmetic acids. Some treatments will be used in a combined manner to check whether it is better to perform one treatment using a device or, for example, combine two types of treatments.

Who can participate?
Female volunteers aged 18 to 25 who suffer with acne vulgaris

What does the study involve?
Six sessions of treatment will be performed with different combinations of carboxytherapy, oxybrasion, cosmetic acids and hydrogen purification. Before the treatment series, 1 week and 14 days after the end of the sessions, skin measurements will be taken and questionnaires will be filled out.

What are the possible benefits and risks of participating?
Possible benefits include reduced skin oiling and efflorescence (redness), higher skin moisture, and better quality of life after treatments. There are no expected risks.

Where is the study run from?
Public Higher Medical Professional School in Opole (Poland)

When is the study starting and how long is it expected to run for?
October 2020 to June 2024

Study information

Scientific title

Assessment of selected skin parameters and quality of life after cosmetic procedures in people with acne vulgaris and oily skin


Study hypothesis

1. Cosmetic treatments decrease the oiling of the skin
2. Cosmetic treatments increase the moisture of the skin
3. Cosmetic treatments act anti-inflammatory on skin efflorescence

Acne vulgaris


Cosmetic treatments will be performed: hydrogen purification, oxybrasion, cosmetic acids, carboxytherapy. The following comparisons of treatments will be made:
1. Oxybrasion (20 people) - hydrogen purification (20 people)
2. Oxybrasion (20 people) - cosmetic acids (20 people)
3. Hydrogen purification (20 people) - cosmetic acids (20 people)
4. Hydrogen purification and cosmetic acids (20 people) - cosmetic acids (20 people)
5. Oxybrasion and cosmetic acids (20 people) - oxybrasion (20 people)
6. Carboxytherapy (20 people) - carboxytherapy and cosmetic acids (20 people)
7. Carboxytherapy (40 people) - carboxytherapy and hydrogen purification (40 people)
8. Carboxytherapy (20 people) - carboxytherapy and oxybrasion (20 people)

The following parameters will also be checked: oiling, pH and skin hydration. Measurements will be made between the eyebrows, 1 cm from the left and right wing of the nose and 1 cm from the lower lip (in the chin area). Every treatment will be performed over a 14-day interval.

After this time skin parameters will be measured (14 and 30 days after finishing sessions). Skin sebum (oily secretion) level, hydration and pH of skin will be compared between these two groups. Participants will have skin sebum level, hydration, and pH checked using a SebumeterⓇ, CorneometerⓇ, and skin pH meter respectively. Quality of life will be checked by using DLQi and Skindes-29 questionnaires before and after finishing treatments. After all sessions, the follow-up measurements will be made after.
