Questions and answers

What the research says

• A hyperoside-enriched fraction of Houttuynia cordata Thunb. inhibited UVB-induced oxidative stress, inflammation, and collagen degradation in human dermal fibroblasts by regulating the MAPK signaling pathway.

  Plants, 2021

• Houttuynia cordata extract containing hyperoside and quercitrin protected human HaCaT keratinocytes from UVB-induced cell damage, apoptosis, oxidative stress, and inflammation by modulating MAPKs and Akt signaling pathways.

  Antioxidants, 2022

• Fermented Houttuynia cordata extracts reduced oxidative stress, inflammation factors, and inflammatory gene expression while increasing keratin-1 gene expression in H2O2 and UVA-treated human skin keratinocytes more effectively than unfermented extracts.

  Applied Biochemistry and Biotechnology, 2023

• Topical treatment of nicotinamide, alone or in combination with other active ingredients, reduces the progression of skin aging and hyperpigmentation in clinical trials while being well tolerated.

  Antioxidants, 2021

• Quercetin phospholipids 1% cream significantly reduced UV-, histamine-, and chemical-induced skin erythema (-10.05%) and mean wheal diameter in 30 healthy human volunteers, showing comparable efficacy to 1% dexchlorpheniramine cream.

  Clinical, Cosmetic and Investigational Dermatology, 2016

• Quercetin-loaded niosomes formulated with Span60-RH40 at a 9:11 mass ratio improved quercetin solubility, photostability, sustained release, and transdermal penetration, yielding a skin retention 2.95 times higher than quercetin solution.

  Molecules, 2019

• Optimized rutin-loaded glycerosomes formulated into a nanosunscreen gel demonstrated sustained drug release, greater skin permeation, good antioxidant activity, and better epidermal retention compared to the dermis, indicating high safety, stability, and sun protection factor values for topical administration.

  Gels, 2023

• 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

• 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

• 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

• 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

• Microencapsulation of ethylhexyl triazone in lipid microparticles significantly reduced its in vivo human stratum corneum penetration by 45.7% compared to the nonencapsulated sunscreen.

  Skin Pharmacology and Physiology, 2019

• A topical sunscreen containing octyl triazone, phenylbenzimidazole sulfonic acid, and methylbenzylidene camphor prevented UVB-induced suppression of intercellular adhesion molecule-1 expression and mixed-lymphocyte reaction in epidermal cell cultures compared to control sunscreens with comparable SPF lacking octyl triazone.

  Toxicology in Vitro, 1994

• Oral and dermal administration of Uvinul A plus resulted in three major urinary metabolites accounting for 52% of the oral dose, with a very low estimated daily systemic exposure of 8.1-9.3 μg/d in volunteers not intentionally exposed.
