## What the research says

- Topical application of an emulsion containing a complete mixture of ceramides III, IIIB, VI, phytosphingosine, cholesterol, and linoleic acid significantly accelerated barrier recovery after SLS damage and improved skin hydration after acetone treatment in human volunteers compared to an emulsion containing only two types of ceramides. ([Journal of the European Academy of Dermatology and Venereology, 2002](https://pubmed.ncbi.nlm.nih.gov/12482041/))
- 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](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- 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](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- 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](https://pubmed.ncbi.nlm.nih.gov/31311529/))
- 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/))
- Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups. ([Military Medicine, 2024](https://pubmed.ncbi.nlm.nih.gov/38771104/))
- A dimethicone skin protectant lotion significantly decreased visual scoring and transepidermal water loss compared to vehicle control and SLS-only treated sites in 12 healthy humans exposed to sodium lauryl sulfate. ([Skin Research and Technology, 2000](https://pubmed.ncbi.nlm.nih.gov/11428946/))
- Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms. ([Clinical and Experimental Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17137484/))
- Topical moisturizers improved skin barrier function and surface moisture, while a postbiotic moisturizer with yeast extract uniquely supported microbiome balance and modulated biomarkers of skin barrier, structure, and inflammation in participants and ex vivo explants exposed to environmental aggressors.

- A maintenance therapy with a cosmeceutical formulation containing hydroxyphenoxy propionic acid, ellagic acid, yeast extract, and salicylic acid over 20 weeks significantly improved even skin tone, spot intensity, spot size, and overall hyperpigmentation in 33 healthy subjects with moderate facial dyspigmentation. ([Journal of Drugs in Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25844613/))
