- Polyvinyl pyrrolidone-K90/Eudragit RL100 dissolving microneedle patches loaded with alpha-arbutin and resveratrol enhanced intradermal delivery by approximately 2.6 times compared to cream and slightly decreased the melanin index in human participants without causing skin irritation. ([Biomaterials Science, 2023](https://pubmed.ncbi.nlm.nih.gov/37183632/))
- Citrus junos callus extract decreased melanin content in melanocytes 1.85-fold compared with arbutin and promoted the proliferation of and procollagen synthesis by human fibroblasts by 154% and 176% at 500 μg/mL. ([Molecules, 2017](https://pubmed.ncbi.nlm.nih.gov/29232889/))

([Antioxidants, 2022](https://pubmed.ncbi.nlm.nih.gov/36670913/))
- Upcycled low-molecular-weight anionic peptides from Citrus junos seeds protected UVR-irradiated keratinocytes and reconstructed skin tissue by scavenging reactive oxygen species, reducing paracrine cytokines, inhibiting melanin synthesis and TRP-2 expression, and increasing filaggrin, laminin-5, and type I collagen expression. ([International Journal of Molecular Sciences, 2024](https://pubmed.ncbi.nlm.nih.gov/38338991/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women. ([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- 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.

- 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](https://pubmed.ncbi.nlm.nih.gov/41416233/))
- A non-hydroquinone topical formulation (SKNB19) improved hyperpigmentation by 28.5% in patient self-assessment and 27% in independent reviewer assessment compared with 4% hydroquinone in 18 adult subjects, while showing significantly less irritation and better tolerability. ([Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/33022197/))
- Encapsulation of alpha arbutin in an optimized ethosomal gel significantly improved skin melanin reduction, moisture content, and elasticity in human volunteers compared to conventional formulations. ([Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/))

- Licochalcone A activated Nrf2 signaling, elevated cytoprotective enzymes, increased the reduced-to-oxidized glutathione ratio, and decreased reactive oxygen species in human fibroblasts and neutrophils, while a LicA-rich licorice extract lowered UVA-induced oxidative processes in vivo. ([Experimental Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25381913/))
- Bioactive glycyrrhizic acid and oxymatrine ionic liquid self-assembled nanomicelles significantly promoted the transdermal permeation, subcutaneous retention, and anti-photoaging efficacy of palmitoyl pentapeptide-4 in cellular and animal models compared to unformulated peptide.
