What the research says

• 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

• 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

• 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

• Twice daily application of retinaldehyde 0.1% and 0.05% creams for 3 months improved skin texture and hydration and reduced transepidermal water loss in 40 female Korean volunteers, with only the 0.1% cream significantly improving the melanin index.

  Journal of Cosmetic Dermatology, 2018

• Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance.

  Dermatology, 2002

• Topical 0.05% retinaldehyde applied over 1 year significantly increased epidermal thickness of the temple and cutaneous elasticity compared to an emollient control group in 40 aging skin patients.

  Dermatology, 1999

• 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

• 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

• 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

• 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

• A 0.4% formulation of natural pterostilbene reduced markers of aging, wrinkles, and fine lines while improving skin hydration and elasticity in healthy volunteers over 8 weeks.

  Clinical, Cosmetic and Investigational Dermatology, 2020

• Pterostilbene at 20 μM protected HaCaT keratinocytes from particulate matter-induced damage by reducing intracellular ROS, inhibiting AHR nuclear translocation, suppressing inflammation and aging protein cascades, and rescuing moisturizing protein expression.

  Antioxidants, 2021

• Topical pterostilbene is equally or more potent than resveratrol in inhibiting TPA-induced AP-1, NF-kappaB, COX-2, and iNOS activation in mouse epidermis.

Why other nourishing masks fit sensitive skin better

• Cosmetic formulations containing 5% Centella asiatica extract showed the best efficacy in improving skin moisture and decreasing transepidermal water loss, while also exhibiting antiinflammatory properties in 25 volunteers compared to baseline measurements.

  Indian Journal of Pharmaceutical Sciences, 2016

• 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.
