Evidence

  • Skin effect Human trial Certainty: Moderate Primary source

    In a randomized, placebo-controlled, double-blind trial of 102 women with melasma or solar lentigo, a cream with 2.51% arbutin applied twice daily for 8 weeks lightened discolouration in 75.86% of the melasma group and 56.00% of the solar-lentigo group.

    Who it applies to: Women aged 26-55 with melasma or solar lentigo, applying a 2.51% arbutin cream twice daily for 8 weeks.

    Study limits: The active was an aqueous extract standardised to 2.51% arbutin.

  • Skin effect Human trial Certainty: Moderate Primary source

    In a randomized, double-blind, controlled study of 90 volunteers with melasma, the arbutin-cream arm showed a significant fall in melasma severity score from 12.65 to 10.84 over 12 weeks; two participants had mild erythema and itching that resolved after stopping the cream.

    Who it applies to: Volunteers with melasma using an arbutin cream twice daily for 12 weeks (one of three arms: herbal mixture, arbutin cream, placebo).

    Study limits: Small per-arm sample and a single active agent among three comparison groups; tolerability was good overall with two mild irritation events.

  • 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%.
