Is it suitable during pregnancy?

MamaSkin rates the recorded formula for Kiehl's Midnight Recovery Concentrate as High risk (26/100). This is not a pregnancy-safe recommendation. Discuss alternatives with a qualified healthcare professional.

Why this rating? Manual-review explanation

Manual review 2026-07-28: retailer punctuation and a malformed Rosmarinus Officina-lis spelling prevented the rosemary ingredient from matching. The ingredient list has been canonicalised without changing the formula or MamaSkin's existing rosemary-oil high-risk classification.

22 of 23 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Ingredient ratings and evidence

Rosmarinus Officinalis Leaf Oil

High risk

Rosmarinus officinalis (rosemary) leaf oil is a concentrated fragrance essential oil with chemotype-dependent constituents (often including camphor/1,8-cineole). Pregnancy-specific evidence for topical cosmetic exposure is limited, and camphor-rich oils are commonly advised to avoid in pregnancy; combined with irritation/sensitisation potential, this supports a precautionary high-risk classification—especially in leave-on products.

Rosa Canina Fruit Oil

No known risks

A plant-derived fatty oil or butter used mainly as an emollient, conditioning ingredient or texture agent. Cosmetic safety reviewers concluded that the assessed plant-derived fatty acid oils are safe in current practices of use and concentration. This conclusion applies to cosmetic-grade fixed oils rather than similarly named volatile essential oils. Seed or food allergy may still matter for a susceptible person.

Oenothera Biennis Oil

No known risks

This plant-derived fatty oil or butter is used as an emollient and skin-conditioning ingredient. The Cosmetic Ingredient Review concluded that assessed plant-derived fatty acid oils are safe as used in cosmetics; individual plant allergy and ingredient purity remain practical considerations.

Tocopherol

No known risks

Vitamin E antioxidant used to protect oils and support the skin barrier. Not associated with pregnancy-specific concerns at cosmetic exposure.

Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)

Lavandula Angustifolia Oil

No known risks

Lavender oil is used in cosmetics mainly as a fragrance ingredient. For normal diluted topical cosmetic use, current evidence does not establish a pregnancy-specific concern. This assessment does not cover ingestion, concentrated essential-oil use, or aromatherapy-style exposure. The more relevant practical issues in skincare are irritation or sensitisation in some users, so within this methodology it remains in no known risks.

Pelargonium Graveolens Flower Oil

No known risks

Geranium oil is used in cosmetics mainly as a fragrance botanical. Direct pregnancy-specific data are sparse, but no clear pregnancy-specific dermal harm signal has been established for routine diluted cosmetic use. This assessment does not cover concentrated essential-oil use, ingestion, or non-cosmetic therapeutic exposure. The more relevant practical issues are fragrance sensitisation and local irritation, so within this methodology it remains in no known risks.

Linalool

No known risks

Linalool is a common fragrance component used at low levels in cosmetics; it is not a pregnancy-specific concern in topical use, but it is a recognised fragrance allergen and may trigger irritation or sensitisation in some people, especially if the product oxidises over time.

Sources: EU/UK cosmetics (fragrance allergen labelling); IFRA; toxicology reviews

Citronellol

No known risks

A rose-like fragrance ingredient that occurs naturally in many essential oils and may also be manufactured. Its main cosmetic concern is contact allergy in susceptible users; no pregnancy-specific hazard is identified for normal topical cosmetic exposure.

Lavandin oil, a volatile fragrance oil that may irritate or sensitise susceptible skin. Available cosmetic and fragrance information focuses on irritation, sensitisation and constituent quality. No pregnancy-specific hazard was identified for normal topical exposure to a compliant finished cosmetic.

Sources: European Commission CosIng ingredient inventory; Cosmetic Ingredient Review botanical safety-assessment framework and relevant ingredient-family assessments. No ingredient-specific human pregnancy study of normal topical cosmetic use was identified.

Cucumis Sativus Extract

No known risks

Direct pregnancy studies of this exact cosmetic material were not identified, but no reproductive or developmental hazard was identified for normal topical exposure. Oral herbal or medicinal use is outside this classification.

Sources: European Commission CosIng ingredient inventory; CIR botanical safety framework and relevant plant-derived ingredient assessments; no ingredient-specific human pregnancy study of normal topical cosmetic use was identified.

Curcuma Longa Root Extract

No known risks

Turmeric root extract is used for antioxidant and skin-conditioning effects. Pregnancy cautions relate mainly to concentrated oral supplements; normal topical cosmetic exposure is substantially smaller. The principal topical concern is irritation or allergy in sensitive users.

Sources: EU/UK cosmetics (fragrance allergen labelling); IFRA; toxicology reviews

Citral

No known risks

Questions about this assessment

Why does Kiehl's Midnight Recovery Concentrate have a High risk rating?

Manual review 2026-07-28: retailer punctuation and a malformed Rosmarinus Officina-lis spelling prevented the rosemary ingredient from matching. The ingredient list has been canonicalised without changing the formula or MamaSkin's existing rosemary-oil high-risk classification. Incomplete ingredient documentation does not establish safety; see the coverage answer and grey entries below.

Has every ingredient in Kiehl's Midnight Recovery Concentrate been assessed?

22 of 23 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Does this assessment apply to my Kiehl's Midnight Recovery Concentrate?

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.
