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: Low Primary source

  Eight weeks of a low-molecular-weight "nano" hyaluronic acid lotion, serum and cream reduced measured periorbital wrinkle depth by up to 40% and raised corneometer hydration by up to 96%.

  Who it applies to: A three-step regimen (lotion, serum, cream) built on a low-molecular-weight hyaluronic acid, used for eight weeks on women with a mean age of 45.2.

  Study limits: The percentages are within-group changes. 33 participants in one centre, and the material is described as "nano" hyaluronic acid.

• 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.

• How deep it gets In vitro study Certainty: Low Primary source

  In reconstituted human epidermis, hyaluronic acid of about 50 kDa penetrated better than the larger grades and increased expression of genes and proteins involved in tight-junction formation and keratinocyte cohesion; its TNF-α expression stayed close from the 20 kDa grade.

  Who it applies to: Reconstituted human epidermis incubated with hyaluronic acid of 20, 50, 130, 300, 800 and 1500 kDa.

  Study limits: The material tested is a defined ~50 kDa grade.

• 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

• Irritation Official ingredient listing Certainty: Moderate Public database

  Cleansing surfactants remove surface oil along with dirt, which can leave skin feeling tight or dry.

  Who it applies to: Rinse-off cleansers. Mildness depends on the whole surfactant system. · Ingredient database · SODIUM LAUROYL SARCOSINATE · COCAMIDOPROPYL HYDROXYSULTAINE · SODIUM METHYL COCOYL TAURATE

  Study limits: Surfactant mildness is a property of the blend. · Ingredient database · SODIUM LAUROYL SARCOSINATE · COCAMIDOPROPYL HYDROXYSULTAINE · SODIUM METHYL COCOYL TAURATE

• 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%.
