Evidence
- Skin effect Human trial Certainty: Moderate Primary source
In a randomized, double-blind, four-arm crossover study of 51 healthy volunteers with dry skin, an emollient containing glycerol and petrolatum raised corneometry-measured skin moisture significantly above its vehicle (P < 0.0001) over 12 hours. The authors attributed the hydration gain to the glycerol component and the lower water loss to the petrolatum component.
Who it applies to: Corneometry (skin moisture) and transepidermal water loss over 12 hours after one application.
Study limits: Measured on the forearms. The significant hydration result comes from the full emollient containing both glycerol and petrolatum.
- Skin effect Review article Certainty: Moderate Primary source
Topical glycerol improves stratum corneum hydration, barrier function and skin mechanical properties. The review also reports reduced irritation response and faster wound healing, and traces the effect to aquaporin-3 transport and to glycerol's own presence in the skin.
Who it applies to: Leave-on products. The review discusses both healthy skin and skin with dry or barrier-impaired conditions such as atopic dermatitis.
Study limits: A narrative review. It compiles mechanisms and results from other studies.
- Skin effect Official ingredient listing Certainty: High Public database
Glycerin is classified as a humectant in cosmetic ingredient databases: its role in a formula is to hold water.
Who it applies to: Cosmetic formulas generally. · Ingredient database · GLYCERIN
Study limits: Skin effect of to the stratum corneum comes from a separate review of the literature. · Ingredient database · GLYCERIN
- Skin effect Human trial Certainty: Moderate Primary source
All five 0.1% hyaluronic acid creams tested, from 50 kDa to 2000 kDa, raised skin hydration and overall elasticity above the vehicle cream applied to the other eye at 60 days.
Who it applies to: 0.1% hyaluronic acid creams applied twice daily for 60 days to the eye area of women aged 30-60 with periocular wrinkles.
Study limits: Sixty days, and the vehicle sat on the fellow eye. Hydration and elasticity were read by instruments. The volunteers were women aged 30-60 with eye-area wrinkles.
- How deep it gets In vitro study Certainty: Moderate Primary source
Hyaluronic acid of 20-300 kDa crossed the stratum corneum in excised human skin, while hyaluronic acid of 1000-1400 kDa remained in the stratum corneum.
Who it applies to: Excised human skin with intact stratum corneum, measured by Raman micro-imaging after topical application.
Study limits: One laboratory's imaging study. Three molecular-weight grades were tested. "remains above" describes intact stratum corneum in this ex vivo setup.
- Skin effect Brand claim Certainty: Moderate Public database
Hyaluronic acid and its salt bind water at the skin surface, giving a plumper look immediately after application.
Who it applies to: Leave-on hydrating products.
Study limits: The effect is largely surface and temporary. In dry air a humectant. · Finding · Sodium hyaluronate · Hydrolyzed hyaluronic acid
- Legal limits Official legal text Certainty: High Primary source
US regulation lists dimethicone as a permitted active ingredient in over-the-counter skin protectant products, at 1 to 30 percent. That is a legal status in one market, and it puts dimethicone in the same list as petrolatum, glycerin and colloidal oatmeal.
Who it applies to: Products sold in the US that make a skin-protectant claim, with dimethicone between 1 and 30 percent.
Study limits: A monograph entry sets what may be sold and what may be claimed. · 1993 · Consumers of over-the-counter skin protectant products in the US.
- Legal limits Official legal text Certainty: High Primary source
The EU Scientific Committee on Consumer Safety concluded in 2016 that 2-phenoxyethanol is safe as a preservative at a maximum of 1.0%, which is the limit already set in Annex V/29 of the EU Cosmetics Regulation. It estimated a margin of safety of about 50 for children.
Who it applies to: Phenoxyethanol used as a preservative in cosmetic products, at or below 1.0%.
Study limits: The dossier behind the conclusion was submitted by Cosmetics Europe, the industry association, and the committee lowered the default toxicokinetic factor from 4.0 to 1.0 on its way to the 1.0% conclusion. The final opinion kept 1.0%.
