Questions and answers

What the research says

• Topical application of Gentiana lutea extract reduced average roughness, relief of the upper eyelid skin, and redness of dark circles in 22 subjects after 14 days compared to placebo.

  International Journal of Cosmetic Science, 2023

• Emulgels containing Perilla frutescens seed oil, Moringa oleifera seed oil, and mixed seed oil microemulsions exhibit good stability, lack of cytotoxicity in PBMC, and no skin irritation or allergic reactions in human subjects.

  Polymers, 2022

• Topical application of micronised titanium dioxide results in no dermal absorption, with the particles being deposited solely on the outermost surface of the stratum corneum.

  Skin Pharmacology and Applied Skin Physiology, 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.

  International Journal of Hygiene and Environmental Health, 2020

• Microfine titanium dioxide does not penetrate human skin when formulated in an oil-in-water emulsion with the pigment dispersed in the aqueous phase, compared to oily dispersions and liposomal encapsulation which allow deeper skin penetration.

  International Journal of Cosmetic Science, 2000

• Replacing microsized titanium dioxide and zinc oxide with nanoparticles in sunscreens eliminates opaqueness and alters UV protection balance while inducing (photo)cyto- and genotoxicity and penetrating viable skin layers during long-term exposures.

  Nanotechnology, Science and Applications, 2011

• Microfine zinc oxide and titanium dioxide do not penetrate the stratum corneum of porcine skin in vitro, indicating that their use in sunscreens does not pose a health risk from internal exposure.

  Toxicology in Vitro, 2006

• Gentiana lutea extract increases lipid synthesis and triglyceride levels in human primary keratinocytes in vitro via p38 MAPK and PPARgamma signaling, and significantly increases skin lipid content in a proof-of-concept trial of 33 volunteers compared to placebo.

  International Journal of Molecular Sciences, 2017

• Aqueous standardized leaf extracts of Moringa oleifera showed the highest human dermal fibroblast and human keratinocyte proliferation and migration properties, leading to the development of an alginate-pectin film dressing with optimal physicochemical properties.

  Journal of Ethnopharmacology, 2018

• Topical administration of Moringa oleifera seed extract on excision wounds in male albino rabbits significantly increased the wound healing rate, elevated TGF-β1, VEGF, and Type I collagen relative expression, and reduced inflammatory markers like IL-1β and TNF-α compared to untreated and MEBO-treated groups.

  Antioxidants, 2022

• Moringa oleifera leaf extracts provided significant UV protection with an SPF of 2 at 2% to 4% concentrations and showed no significant irritant potential in cosmetic formulations.
