- Chronomodulated daytime application of baicalin and nighttime application of palmitoyl tripeptide-1 synergistically improved skin luminance by 16.29%, nasolabial fold depth by -36.35%, and firmness by 24.35% in 30 female participants. ([Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/))
- A multi-modal methodology combining MALDI-MSI, in vivo RCM, echography, and histology revealed age-related decreases in extracellular matrix and epidermal-dermal junction proteins and undulation depth, while a blend of palmitoyl oligopeptide and palmitoyl tetrapeptide-7 improved subepidermal low-echogenic band thickness, density, and extracellular matrix structure compared to placebo. ([Journal of Cosmetic Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25817264/))
- Palmitoyl tetrapeptide-7, acetyl hexapeptide-8, palmitoyl tripeptide-1, and palmitoyl tetrapeptide-10 significantly increased type III collagen levels in human dermal fibroblasts following UV exposure, with their combination demonstrating a greater effect in vitro and enhancing type I, III, and IV collagen levels in ex vivo skin tissues compared to individual components. ([International Journal of Cosmetic Science, 2026](https://pubmed.ncbi.nlm.nih.gov/42683869/))
- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Enzyme-modified ginseng extract cream significantly reduced the global photo-damage score and various roughness measures including total roughness, smoothness depth, and arithmetic roughness average compared to placebo in 23 human subjects. ([Rejuvenation Research, 2015](https://pubmed.ncbi.nlm.nih.gov/25867599/))
- A red ginseng hydrogel formulation with 1,2-hexanediol promoted selective growth of Staphylococcus epidermidis and decreased Cutibacterium acnes in 20 female subjects. ([Journal of Ginseng Research, 2022](https://pubmed.ncbi.nlm.nih.gov/35509819/))
