Plain English Summary
Background and study aims
Hydrogen, a natural element with unusual properties, introduced into the skin with the help of a device, primarily slows down the aging process by neutralizing oxygen free radicals, has anti-inflammatory and cleansing effects. The aim of the test is to check how the hydrogen cleansing treatment will affect the skin parameters such as pH, hydration and oiling in healthy and acne vulgaris group.
Who can participate?
Healthy young Polish female volunteers with mild to moderate acne vulgaris or with healthy skin, aged 19-25
What does the study involve?
Hydrogen cleansing will be performed on the cleansed face skin, using a special plastic tip that sucks the skin fold and at the same time washing it with hydrogen water (created thanks to the generator in the device). After all sessions, the follow-up measurements will be made after 7 and 14 days.
What are the possible benefits and risks of participating?
Benefits: Improved skin health.
Risks: There is no possibile risks of participating, only after treatment skin is a little bit red, but after 10 minutes it stops, it is very safe treatment.
Where is the study run from?

The effect of hydrogen purification on selected skin parameters of healthy women and suffering from acne vulgaris
1. Hydrogen purification decreases the oiling of skin
2. Hydrogen purification increases the moisture of skin
3. Hydrogen purification acts anti-inflammatory on skin efflorescence

Patient information sheet
Participants are recruited into 2 groups:
1st group - healthy women (lower level of sebum)
2nd group - women from mild to moderate acne vulgaris (higher level of sebum)
Other parameters also will be checked: pH and skin hydration. Measurements will be made between the eyebrows, 1 cm from the wing of the nose and 1 cm from the lower lip (in the chin area).
Four sessions of hydrogen purification are performed weekly. After this time skin parameters will be measured (7 and 14 days after finishing the hydrogen purification sessions). Skin sebum (oily secretion) level, hydration and pH of skin will be compared between these two groups. Hydrogen cleansing will be performed on the cleansed face skin, using a special plastic tip that sucks the skin fold and at the same time washing it with hydrogen water (created thanks to the generator in the device). After all sessions, the follow-up measurements will be made after 7 and 14 days.
Primary outcome measure
Skin sebum content measured using the SebumeterⓇ at baseline, one-week and two-weeks after finishing the treatments
Secondary outcome measures
1. Skin hydration measured using a CorneometerⓇ at baseline, one-week and two-weeks after finishing the treatments
2. Transepidermal pH measured using Skin-pH-Meter at baseline, one-week and two-weeks after finishing the treatments
3. General quality of life of patients with acne vulgaris measured using the Hellgren and Vincent Scale at baseline and two weeks after finishing the treatments
