Questions and answers

What the research says

• Topical dexpanthenol acts as a moisturizer, improves stratum corneum hydration, accelerates wound healing and epidermal regeneration, reduces erythema, and improves symptoms of skin irritation compared to vehicle or no pretreatment.

  American Journal of Clinical Dermatology, 2002

• A new topical panthenol-containing emollient significantly improved transepidermal water loss reduction, stratum corneum hydration, and intercellular lipid lamellae length compared with control in healthy subjects without negatively impacting bacterial viability.

  The Journal of Dermatological Treatment, 2017

• Parsol 1789 and Eusolex 8020 provided slightly better photoprotection than oxybenzone in both normal and sensitized human skin when assessed using pigmentation end points, whereas all three sunscreens performed similarly against UVA-induced erythema.

  Journal of the American Academy of Dermatology, 1987

• Encapsulating avobenzone in low-porosity TiO2-embedded mesoporous silica (TiO2/SBA-S) reduced cutaneous avobenzone absorption from 0.76 to 0.50 nmol/mg while providing effective pollutant adsorbability, UVA protection, and a two- to three-fold reduction in photoaged skin cytokines/chemokines compared to the non-treatment control.

  European Journal of Pharmaceutical Sciences, 2023

• Incorporation of avobenzone and oxybenzone into ordered mesoporous silica SBA-15 significantly reduced their cutaneous penetration and transdermal permeation in porcine skin compared to free filters, while enhancing the sun protection factor by 94%.

  International Journal of Pharmaceutics, 2019

• Encapsulation of ethylhexyl methoxycinnamate and butyl methoxydibenzoylmethane in lipid microparticles significantly reduced their in vivo human skin penetration compared to nonencapsulated filters.

  Skin Pharmacology and Physiology, 2011

• Microencapsulation of the BMDBM/HP-beta-CD complex in lipid microparticles significantly decreased the percutaneous penetration of the UV filter into the stratum corneum of human volunteers compared to the non-encapsulated sunscreen agent.

  Journal of Pharmaceutical and Biomedical Analysis, 2011

• Following human skin application of an O/W emulsion containing 2% BMDBM loaded in lipospheres, 15% of the sunscreen accumulated in the uppermost layers of the stratum corneum without remarkably modifying skin permeation compared to unencapsulated sunscreen.

  Skin Pharmacology and Physiology, 2008

• 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

• 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

• 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

• Maximal topical applications of 6% bemotrizinol in a model sunscreen formulation did not result in meaningful systemic exposure in humans.
