Plain English Summary
Background and study aims
Cosmetic acids are a procedure that can be used for people suffering from acne vulgaris. Both pyruvic acid and azelaic acid can be used for treatments that are aimed at reducing skin greasiness, as well as reducing skin porosity.
The aim of the test is to check how both acids will affect skin parameters, quality of life and if one of these cosmetic acids will be better for acne vulgaris skin.
Who can participate?
Polish female volunteers with mild to moderate acne vulgaris or with healthy skin, aged 18-25
What does the study involve?
Cosmetic acids will be performed on the cleansed face skin, using a cotton stick, then neutralizer will be put on the skin, and rinsed by cold water.
After all the sessions, the follow-up measurements will be made after 14 days.
What are the possible benefits and risks of participating?
Benefits: Improved skin health.
Risks: There is no possible risks of participating, only after treatment skin is a little bit red, but after 1-2 hours it stops.
Where is the study run from?
Opole Medical School - Faculty of Health Science (Poland)
When is the study starting and how long is it expected to run for?
January 2020 to April 2020

The impact of treatments using pyruvic and azelaic acids on selected skin parameters and quality of life from people suffering from acne vulgaris
1. Treatment with cosmetic acids decreases the oiling of skin
2. Treatment with cosmetic acids increases the quality of life
3. Treatment with cosmetic acids acts anti-inflammatory on skin efflorescence

Prospective clinical study with follow-up analysis

Secondary study design
Non randomised study
Patient information sheet
Participants are recruited into 2 groups:
1st group - treatment with pyruvic acid
2nd group - treatment with azelaic acid
Parameters of the skin will be chececked like: oiling, moisturising, poriosity, peeling by device Nati Skin Analyzer.
Six sessions of cosmetic acids are performed every two weeks. After this time skin parameters will be measured (14 days after last session). Skin parameters will be compared between these two groups. Cosmetic acids will be performed on the cleansed face skin, using a cotton stick that, then neutralizer will be used and rinsed by a cold water. After all sessions, the follow-up measurements will be made after 14 days.
Also quality of life will be checked into this two groups, before and after finishing all sessions. DLQI and Skindex-29 will be used.
Pyruvic and Azelaic Acids
Primary outcome measure
Skin sebum content measured using the Nati Skin Analyzer at baseline, and two-weeks after finishing the treatments.
Secondary outcome measures
1. Skin moisture measured using NAti Skin Analyzer at baseline, two-weeks after finishing the treatments
2. Poriosity and peeling of skin will be measured by Nati Skin Analyzer at baseline two-weeks after finishing the treatments
3. General quality of life of patients with acne vulgaris measured using the Hellgren and Vincent Scale and also Skindex-29 and DLQI questionnaries at baseline and two weeks after finishing the treatments
