Why this score

Concern53 / 55
  • Fragrance: watch if sensitive

How much genuine, cited concern the ingredients carry, weighted by how much of each is likely present and whether the product stays on or rinses off.

Transparency12 / 20
  • Uses an undisclosed "fragrance/parfum" blend, so its scent allergens are hidden.

Whether the full ingredient list, and any fragrance, are actually disclosed.

Formulation restraint23 / 25
  • 1 known irritant or fragrance-allergen ingredient: Fragrance.

Needless irritant or allergen load for the product type. A clean, purposeful formula scores well without any "free-from" theater.

Calcium aluminum borosilicate is another engineered borosilicate glass, milled into fine flakes or microspheres and used the same way as its calcium sodium counterpart: as a sparkle and light-diffusing effect pigment in eyeshadow, highlighter, lip products, and nail polish. CIR reviewed it alongside the other borosilicate glasses and concluded it's safe as used, provided the glass meets standard impurity and particle-size specifications.

Full ingredient details →

Silica dimethyl silylate is silica that has been surface-treated with a dimethyl coating so it disperses more easily into oils; it's used as an anti-caking and thickening agent that keeps pressed powders from clumping and helps other ingredients stay evenly suspended.

Full ingredient details →
PhenoxyethanolCommonly feared, low concern

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Full ingredient details →
Hyaluronic AcidGenerally safe

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

Hexylene GlycolGenerally safe

This small glycol is used to thin out formulas and help preservatives work better, similar in role to propylene glycol and butylene glycol already in wide use. Industry and EU safety reviewers have set purity and concentration conditions for its use rather than restricting it outright, and no consumer-relevant hazard has been established at typical cosmetic levels.

Full ingredient details →
FragranceWatch if sensitive

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

Full ingredient details →

Note: this product hides its scent as an undisclosed “fragrance/parfum” blend, so its specific allergens are not on the label.
