Questions and answers

What the research says

• Biomimetic hyaluronic acid-stabilized zinc oxide nanoparticles selectively inhibited C. acnes, outperformed erythromycin in preclinical acne models, and safely reduced acne lesions and redness in a clinical trial.

  Journal of Controlled Release, 2025

• Topical 0.5% hyaluronic-ZnO nanogel applied twice daily reduced inflammatory-lesion counts by 58% at week four in human subjects compared to baseline without causing erythema.

  Biomedicines, 2025

• 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

• Nels cream achieved a similar reduction in inflammatory and noninflammatory lesion counts compared to 5% benzoyl peroxide in acne vulgaris patients, but caused significantly fewer side-effects such as peeling and dryness.

  Clinical and Experimental Dermatology, 2000

• Topically applied coated and uncoated zinc oxide nanoparticles under flexing and massage are retained in the stratum corneum with no significant penetration into the viable epidermis and no cellular toxicity in human skin.

  Nanomedicine, 2016

• Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups.

  Military Medicine, 2024

• Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms.

  Clinical and Experimental Dermatology, 2007

• Externally applied substances such as ceramides, hyaluronic acid, licorice extracts, dimethicone, petrolatum, and paraffin wax treat skin disease resulting from damage to the skin barrier.

  Clinics in Dermatology, 2012

• Application of a cosmetic multiple emulsion containing vitamin C and wheat protein as well as a base formulation increased skin moisture in 11 human volunteers over four weeks, while producing no significant variations in skin sebum, pH, elasticity, melanin, or erythema.

  Pakistan Journal of Pharmaceutical Sciences, 2008

• The addition of polymers and hydrolysed proteins to model body wash cosmetics improves foaming properties, storage stability, and safety by reducing skin irritant potential, with the polyvinylpyrrolidone/hydrolysed wheat protein crosspolymer showing the strongest reduction effect.
