Flagged ingredients (10)

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

Severity 7/10
Sensitive skin: High cautionPregnancy: Best avoidedBabies & kids: Best avoidedEczema-prone: High caution
  • Hormone disruption:Classified as toxic to reproduction (CMR 1B); banned in the EU since March 2022.
  • Allergy risk:Well-documented fragrance sensitizer.
EU CLP Repr. 1B ↗EU CosIng Annex II (prohibited in cosmetics) ↗

The lily-of-the-valley scent 'Lilial', banned in EU cosmetics in 2022 after being classified as presumed toxic to human reproduction. Still legal in some other markets — check older or imported products.

DMDM Hydantoin

preservative

Severity 7/10
Sensitive skin: High cautionPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Cancer concern:Slowly releases formaldehyde, an IARC Group 1 carcinogen.
  • Allergy risk:Frequent cause of preservative contact dermatitis.
EU CosIng Annex V: releases formaldehyde (IARC Group 1) ↗

A formaldehyde-releasing preservative used in creams, shampoos and wipes. The slow formaldehyde release preserves the product but exposes skin to a known carcinogen and allergen.

Severity 5/10Editorial
Oily & acne-prone: Best avoided
  • Pore-clogging:Rated 4/5 on the comedogenic scale; a frequent trigger of facial breakouts.

A beloved natural moisturizer for body and hair that is nonetheless one of the most pore-clogging oils on facial skin.

Severity 5/10Editorial
Oily & acne-prone: Best avoided
  • Pore-clogging:One of the most consistently comedogenic emollients in rabbit-ear and human assays.

A silky-feel emollient that repeatedly tops comedogenicity rankings — acne-prone users should watch for it in face products.

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.

Linalool

fragrance

Severity 5/10
Sensitive skin: Use with cautionEczema-prone: High caution
  • Allergy risk:EU-declarable allergen; oxidized linalool is a common patch-test positive.
EU CLP Skin Sens. 1B ↗EU CosIng Annex III (declarable / restricted) ↗

A floral scent molecule found in lavender and many essential oils. It oxidizes on air exposure into strongly sensitizing compounds, which is why it must be declared on EU labels.

Propylene Glycol

humectant · solvent

Severity 3/10Editorial
Sensitive skin: Use with cautionEczema-prone: High caution
  • Allergy risk:American Contact Dermatitis Society Allergen of the Year 2018.
  • Irritation:Can irritate compromised skin at higher concentrations.

A workhorse humectant and penetration enhancer that is fine for most, but a recurring culprit in eczema patients' patch tests.

Ceteareth-20

emulsifier

Severity 2/10Editorial
Eczema-prone: Use with caution
  • Irritation:Can enhance penetration of other ingredients; avoid on broken skin.

A common emulsifier; CIR advises against use on damaged skin because it can carry other ingredients deeper.

Pore-clogging potential (3)

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 (11)

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

Recognized ingredients (5)

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.

Not enough data (4)

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.

  • Cocos Nucifera (Coconut/Noix de Coco) Water
  • Butyrospermum Parki(Shea) Butter
  • Diezolidinyl Urea
  • lodopropynyl Butylcarbanate

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.
