[Skin quality and ways to improve skin quality].

[BACKGROUND] Skin quality has a significant impact on the perception of attractiveness. Procedures to improve skin quality, whose quality is assured, should have sufficiently documented scientific evidence of in vivo and in vitro efficacy and significant effects proven in studies.

[OBJECTIVES] This paper will present findings from recent studies and experience of experts on skin quality and treatments to improve skin quality.

[MATERIALS AND METHODS] A PubMed database search was conducted in February 2021 on the terms skin quality and minimally invasive skin quality improvement procedures. Two reviewers independently screened the titles, resulting in the selection of 30 papers.

[RESULTS] Hyaluronic acid (HA) is the most commonly studied agent for skin rejuvenation treatments. The efficacy and safety of the superficially injected HA products are excellently proven on the basis of current data. According to these findings, they ensure an improvement of skin quality without significant volume changes. The skin is hydrated, its elasticity increased, the skin surface smoothened, the complexion (skin redness, glow) improved and fine lines and wrinkles are reduced. They are injected intradermally and have a clinically proven effect duration of up to 12 months.

[CONCLUSIONS] Hyaluronic acid is outstandingly suitable for deep hydration of the skin, and its effect is long-term and safe. Natural treatment results fulfil the needs of the patients and increase the patient-practitioner relation. Superficially injected HA products are currently the criterion standard to increase skin quality.
