Flagged ingredients (6)

Ingredients with a documented concern, from official datasets and our reviewed database.

Salicylic Acid

exfoliant · anti-acne

Severity 4/10
Sensitive skin: Use with cautionDry skin: High cautionPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: High caution
  • Irritation:Dryness and peeling at exfoliating concentrations (0.5–2%).

The pore-clearing BHA exfoliant. Not for young children (salicylate absorption), used cautiously in pregnancy at low leave-on concentrations, and drying for compromised barriers.

Parfum

fragrance

Severity 7/10Editorial
Sensitive skin: Best avoidedPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
  • Irritation:Frequent trigger of stinging and redness on reactive skin.
Caredermis curated dermatological review

An umbrella term that can hide dozens of undisclosed scent chemicals. Fragrance is the leading cause of allergic contact dermatitis from cosmetics, and dermatologists routinely advise fragrance-free products for eczema, babies and sensitive skin.

Severity 8/10
Sensitive skin: Best avoidedPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Allergy risk:Caused an epidemic of contact allergy; banned in EU leave-on products.
  • Irritation:Irritating even in people without allergy.

A preservative behind one of the largest contact-allergy epidemics in cosmetic history. The EU banned it from leave-on products and restricts it in rinse-off products to 15 ppm.

Sodium Laureth Sulfate

surfactant · foaming agent

Severity 4/10Editorial
Sensitive skin: High cautionDry skin: Use with cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Irritation:Milder than SLS but still drying for compromised skin.

The gentler cousin of SLS used in most mainstream shampoos and washes. Its manufacturing can leave trace 1,4-dioxane, which reputable makers strip out — an issue of quality control rather than the ingredient itself.

Acrylates Copolymer

film former · thickener

Severity 4/10Editorial
  • Environmental impact:Synthetic polymer counted as a microplastic under the EU restriction when in particle form.

A common film-forming polymer scrutinized under the EU's microplastics restriction; skin safety itself is well established.

Pore-clogging potential (2)

Ingredients rated likely to clog pores — relevant if your skin is acne-prone. This is a separate indicator and is not part of the safety score.

Indicative Fulton-scale ratings from published dermatology references — not a regulator classification; individual reactions vary.

No concerns found (7)

Ingredients that are unflagged in our reviewed database, reviewed safe by the CIR panel, or on an EU permitted list.

Recognized ingredients (1)

Catalogued in official cosmetic-ingredient inventories (EU CosIng and others) with no safety flag on record. Being recognized isn't a safety guarantee — it means the ingredient is on record but no authority has published a concern.

  • crotamiton· antimicrobial, solvent

Not enough data (3)

Not found in any dataset we hold (often trade-name blends or very niche ingredients), so we can't assess them — this is not a safety judgment either way.

  • peg-18 glyceryl oleate/cocoate glycolic acid
  • sodium shale oil
  • sulfonate undecylenamidopropyl betaine

This report is informational, not medical advice. Assessments summarize published findings (EU CosIng, IARC, ECHA, CIR, SCCS and others) about ingredients — not clinical testing of this specific product. Exposure, concentration and individual sensitivity all matter. Consult a dermatologist for medical concerns.
