Questions and answers

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

• 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

• 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

• 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

• 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.

  Skin Research and Technology, 2000

• 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

• A functional cosmetic cream containing bioactive materials from Streptomyces sp. T65 embedded in SBA-15 decreased skin roughness by 4.670% and increased skin brightness by 0.472% after 4 weeks of application, while demonstrating antimicrobial, antioxidant, anti-aging, and whitening activities.

  Antioxidants, 2020

• Film-forming formulations containing porous silica achieved skin permeation rates comparable to immediate release formulations while confirming prolonged drug availability and causing no skin irritation in healthy volunteers.

  European Journal of Pharmaceutical Sciences, 2017

• Topical treatment with silica mud and microalgae extracts from the Blue Lagoon improved skin barrier function by inducing epidermal gene expression and reducing transepidermal water loss in healthy humans, while preventing skin aging markers in vitro.

  Experimental Dermatology, 2008

• 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

• Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects.

  Journal of Drugs in Dermatology, 2012

Why other sunscreens fit dry skin better

• Alpha-tocopherol loaded nanostructured lipid carrier gel provided enhanced moisturizing and anti-aging properties in human volunteers over 12 weeks.

  Journal of Cosmetic Dermatology, 2020

• Co-encapsulation of alpha-tocopherol and alpha-tocopheryl acetate in nanostructured lipid carrier gel formulations significantly enhanced moisture retention up to 68% and improved skin elasticity in human volunteers compared to a solution gel.
