WHY GLOWCHECK IS DIFFERENT
We don't run a blacklist. We do toxicology.
Most beauty apps rate ingredients with a red/yellow/green list. GlowCheck evaluates ingredients using toxicology-informed principles — the same kind of thinking cosmetic safety assessors apply.
01
Exposure
How long an ingredient sits on skin and how much typical use delivers — not just whether it's present.
Solvent, preservative, emulsifier, active, fragrance carrier — function shapes the conversation.
04
Available concentration information
Where labeling, regulatory limits, or position-in-list signals tell us about real-world exposure.
05
Pregnancy & breastfeeding considerations
Optional lens that adjusts what surfaces during sensitive life stages — without alarmism.

A preview of the most-searched cosmetic safety questions. Full FAQ on /faq.
Is phenoxyethanol safe?
Phenoxyethanol is a widely used cosmetic preservative permitted in the US, EU, and most other jurisdictions, typically up to 1%. Independent safety assessments by the Cosmetic Ingredient Review (CIR) Expert Panel and the EU SCCS have concluded it is safe at intended use levels for the general adult population. GlowCheck treats it as a low-concern preservative for most adult exposures, while still surfacing context for sensitive skin or eye-area products.
