Why this score

Concern47 / 55
  • No ingredients carry meaningful, evidence-backed concern.

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.

Transparency20 / 20
  • No hidden fragrance blend.

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

Formulation restraint13 / 25
  • 2 known irritant or fragrance-allergen ingredients: Octocrylene, Alcohol Denat..

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

What’s inside

AvobenzoneGenerally safe

A widely used organic UV-A filter in sunscreens. It can lose effectiveness in sunlight unless paired with photostabilizers, but safety reviews have not found it to pose a meaningful health hazard at approved use levels.

HomosalateLimited concern

A UV-B filter used in sunscreens. After reassessing hormone-activity data, the EU lowered its permitted maximum concentration as a precaution, but concluded the ingredient remains safe for use at the new lower limit.

Full ingredient details →
OctisalateGenerally safe

A mild UVB chemical filter usually used to help dissolve and stabilize other sunscreen actives. It has a long OTC history at US-approved levels with a low rate of reported irritation.

Full ingredient details →
OctocryleneWatch if sensitive

An organic UV-B filter that also stabilizes other sunscreen actives like avobenzone. The EU SCCS reviewed it and concluded it is safe at current use levels, though rare contact allergy has been reported and older, degraded product may form small amounts of benzophenone.

WaterGenerally safe

The base most products are built on. It carries the other ingredients and has no safety concern.

Full ingredient details →
Alcohol Denat.Watch if sensitive

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

Full ingredient details →
Butyloctyl SalicylateGenerally safe

A lightweight salicylate ester used mainly as a solvent to keep avobenzone stable and to give modern sunscreens a non-greasy finish. It has not drawn any published safety flags and functions cosmetically rather than as an active.

Full ingredient details →
Cetearyl AlcoholCommonly feared, low concern

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

Below the 1% line

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 →
GlycerinGenerally safe

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

Full ingredient details →
Disodium EDTACommonly feared, low concern

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

Full ingredient details →
EthylhexylglycerinGenerally safe

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.
