Flagged ingredients (11)

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 4/10Editorial
Sensitive skin: Use with cautionEczema-prone: High caution
  • Irritation:A strong 'sulfate-free' cleanser that can be as stripping as sulfates.

A common 'sulfate-free' marketing substitute that cleans — and can strip — just as aggressively as the sulfates it replaces.

Melaleuca Alternifolia Leaf Oil

antimicrobial · botanical

Severity 5/10Editorial
Sensitive skin: High cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Allergy risk:Oxidized tea tree oil is a well-documented contact allergen.
  • Irritation:Irritating when used undiluted or at high concentrations.

A popular natural antibacterial for blemishes that becomes increasingly allergenic as it ages and oxidizes; never use it undiluted.

Menthol

cooling agent · fragrance

Severity 4/10Editorial
Sensitive skin: High cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Irritation:Sensory irritant; the cooling feeling signals nerve stimulation, not soothing.

The cooling molecule from mint. Refreshing on healthy skin but a genuine irritant for reactive, broken or infant skin.

Severity 4/10Editorial
Sensitive skin: Use with cautionEczema-prone: Use with caution
  • Allergy risk:Named Allergen of the Year 2004; impurities (amidoamine) drive most reactions.

A mild coconut-derived surfactant in countless 'gentle' cleansers. Most allergy is caused by manufacturing impurities, so quality varies by brand.

Phenoxyethanol

preservative

Severity 3/10
Babies & kids: Use with caution
  • Irritation:Occasional stinging and irritation, mostly around eyes and on damaged skin.

Today's most common preservative, considered safe by the SCCS up to 1%. French authorities advise avoiding it in wipes and diaper-area products for children under 3 as a precaution.

Ethylhexylglycerin

preservative booster · skin conditioning

Severity 2/10
  • Irritation:Documented occasional contact allergy and eye irritation.

A preservative booster often paired with phenoxyethanol; low-risk overall with rare reports of contact allergy.

Disodium EDTA

chelating agent

Severity 3/10Editorial
  • Environmental impact:Poorly biodegradable; can remobilize heavy metals in waterways.

A metal-binding stabilizer that is safe on skin at the tiny amounts used; its criticism is environmental persistence.

No concerns found (4)

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.

Not enough data (5)

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.

  • PSIDIUM GUAJAVA LEAF EXTRACT (GUAVA)

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.
