Split‐face evaluation: Gluconolactone plus oxybrasion versus gluconolactone plus microneedling. The effects on skin parameters.

Background: The application of polyhydroxy acids and alpha‐hydroxy acids to the skin is often used in cosmetology. To enhance the effect of gluconolactone chemical peeling, a combined method including water‐oxygen oxybrasion or microneedle mesotherapy can be used. Objectives: To evaluate skin parameters such as hydration, sebum, pH and TEWL after application of a 10% gluconolactone chemical peel in combination with oxybrasion and microneedling. Materials and methods: Twenty‐one Caucasian women participated in the study. A series of three split face treatments was carried out at 1‐week intervals. Oxybrasion was performed on the right side of the face and micro‐needle mesotherapy on the left side. A 10% gluconolactone solution was applied to the entire face. Before the first and third treatments and 2 weeks after the last treatment, skin parameters were evaluated. Photographic documentation was also made before and after the treatment series. Results and conclusion: Evaluation of skin parameters using Courage & Khazaka 580 Multi Probe Adapter probes (Courage + Khazaka electronic GmbH, Cologne, Germany) showed an increase in hydration and a decrease in sebum, pH and TEWL for both treatments. There were no statistically significant differences between the treatments. Combining chemical peeling of gluconolactone with oxybrasion and microneedle mesotherapy is a good method to seal the hydrolipid barrier and increase skin hydration. [ABSTRACT FROM AUTHOR]
