Ingredient ratings and evidence

Higher-risk flags first. Open an ingredient for evidence.

Phenoxyethanol

Low risk

Phenoxyethanol is a preservative permitted in EU cosmetics up to 1.0%. The SCCS concluded it is safe for cosmetic use at that level, including when considering higher cosmetic exposure scenarios in infants and young children. Main practical concern is irritation/stinging on very sensitive or compromised skin rather than a pregnancy- or breastfeeding-specific risk.

Water

No known risks

Water (Aqua) is the standard purified water used as a cosmetic solvent. It has no pregnancy-specific risk in normal topical use.

Questions about this assessment

Why does The Ordinary Multi-Peptide Lash And Brow Serum have a Low risk rating?

The recorded formula includes 1 ingredient entry with a risk flag: Phenoxyethanol (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. The product score is a stored assessment, not a clinical safety guarantee.

Does a barrier-care product name establish pregnancy suitability?

No. This recorded formula contains Panthenol or Madecassoside, but a barrier-care claim does not establish the assessment of all its other ingredients. Read the individual ingredient evidence and any manual-review explanation, and compare the recorded list with your packaging.

Has every ingredient in The Ordinary Multi-Peptide Lash And Brow Serum been assessed?

30 of 30 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.

Does this assessment apply to my The Ordinary Multi-Peptide Lash And Brow Serum?

Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.

Does this pregnancy assessment also establish breastfeeding suitability?

No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.
