  Journal of Cosmetic Dermatology, 2022

• Topical treatment with 5% vitamin C and 0.1% madecassoside significantly improved clinical scores for wrinkles, suppleness, firmness, roughness, and skin hydration, along with functional and structural remodeling of the elastic fiber network in 20 female volunteers with photoaged skin after 6 months compared to baseline.

  Experimental Dermatology, 2008

• Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.

  Journal of Drugs in Dermatology, 2011

• Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

  Clinical Oral Investigations, 2022

• Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days.

  BMC Oral Health, 2019

• Glutathione amino acid precursors effectively increase cellular glutathione levels, reducing oxidative stress, ATP depletion, and DNA damage in human keratinocytes, clinical subjects, and ex vivo skin compared to controls.

  Journal of the European Academy of Dermatology and Venereology, 2024

• Topical oxidized glutathione significantly decreases the skin melanin index and improves moisture content, smoothness, wrinkle formation, and elasticity compared to placebo in healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2014

• Topical glutathione improves hyperpigmentation, reduces ultraviolet-induced erythema and wrinkles, decreases transepidermal water loss, and enhances antioxidant capacity.

  The Journal of Clinical and Aesthetic Dermatology, 2025

• Squalane at 0.005-0.015% counteracts UVA-induced oxidative stress, inflammation, and collagen metabolism inhibition while stimulating fibroblast migration in human dermal fibroblasts.

  Molecules, 2025

• Plant-derived squalane protected human dermal fibroblasts against UVA-induced damage by counteracting ROS formation, suppressing apoptosis-related proteins p53, caspase-3, caspase-9, and PARP, and restoring the pro-survival p-Akt/mTOR pathway.
