Abstract

There is growing interest in combining topical treatments with aesthetic procedures to combat signs of aging skin. This study aimed to assess the efficacy and tolerability of a novel cosmetic serum containing 5 different forms of HA (HA5 DG) when used via a proprietary diamond-tip microdermabrasion procedure (DG) to treat skin dryness, fine lines/wrinkles, rough texture, and dullness. In this open-label, single-center study, participants received HA5 DG as part of a biweekly DG procedure on the face and neck for 12 weeks. Study participants also applied another take-home HA5 serum to the face twice daily at home, along with a basic skincare regimen. The efficacy of the combined treatment was measured by clinical quantification of multiple skin appearance features, analysis of bioinstrumental measurements, and digital photography. This study enrolled 27 participants, with an average age of 42.7 years and Fitzpatrick skin phototypes I-III (59.3%), IV (18.5%), and V-VI (22.2%), and 23 participants completed the study. The combined treatment had effects in fine lines/wrinkles, skin dryness, smoothness, radiance, firmness, and hydration 15 minutes post-DG. Furthermore, the significant improvements observed in dryness, fine lines/wrinkles, skin smoothness, and radiance were still visible 3 days after and maintained at week 12. Additionally, smoothing of coarse lines/wrinkles, improvement of skin tone evenness, hyperpigmentation, photodamage, and transepidermal water loss were observed at week 12. The treatment had a favorable tolerability profile and was perceived as efficacious and highly satisfactory. This novel combined treatment delivered immediate and prolonged skin hydration and high participant satisfaction, proving it can be an excellent approach for skin rejuvenation.
