Ingredient ratings and evidence
Higher-risk flags first. Open an ingredient for evidence.
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.

Propanediol
No known risks
Solvent and humectant used to improve texture and ingredient solubility. Low systemic exposure expected from topical cosmetic use.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
Ascorbic Acid
No known risks
Vitamin C antioxidant used to support brightness and photoprotection; functions as an antioxidant/pH adjuster in cosmetic formulas. No pregnancy-specific contraindications are identified for topical cosmetic use.
Sources: CIR (Ascorbic Acid); PubMed (NLM)
Ethoxydiglycol
No known risks
A glycol ether used as a cosmetic solvent and delivery aid. Cosmetic safety reviewers concluded that ethoxydiglycol is safe as used in cosmetics, with low toxicity in the reviewed exposure data. It is distinct from ethoxyethanol, which has a different and less favourable safety assessment.

Isopentyldiol
No known risks
A small alkane diol used as a solvent, humectant and preservative-support ingredient. Cosmetic safety reviewers concluded that alkane diols, including isopentyldiol, are safe in current practices of use and concentration. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

Ferulic Acid
No known risks
A plant-derived phenolic antioxidant used to stabilise formulas and support photoprotection. Ferulic acid is extensively metabolised after dietary exposure, and normal topical cosmetic use is expected to produce far lower systemic exposure. No pregnancy- or breastfeeding-specific hazard signal was identified in the topical and toxicology literature reviewed; irritation remains possible in acidic formulas.
Sources: European Commission CosIng ingredient inventory; PubMed literature on topical ferulic acid, dermal delivery and antioxidant use; ECHA substance information for ferulic acid.
Ergothioneine
No known risks
A naturally occurring small molecule used for antioxidant, conditioning or cellular-energy support in cosmetics. Creatine and ergothioneine occur in human or dietary biology, and no pregnancy-specific hazard signal was identified for the much smaller exposure expected from normal topical cosmetic use. This classification does not assess concentrated oral supplements.
Sources: European Commission CosIng ingredient inventory; PubMed literature on topical Creatine and Ergothioneine, dermal delivery and cosmetic use; ECHA substance information where available.
Inulin
No known risks
A plant-derived polysaccharide used for conditioning and formula texture. Cosmetic safety reviewers included inulin in the plant polysaccharide gums group and concluded that the group is safe in current practices of use and concentration. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

Niacinamide
No known risks
Niacinamide (vitamin B3) is widely used for barrier support and tone/texture benefits, and is generally considered safe in pregnancy and breastfeeding when used topically at cosmetic concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
Hydroxyacetophenone
No known risks
Hydroxyacetophenone is used as an antioxidant and preservative-support ingredient; it is generally considered low concern in topical cosmetic use with no known pregnancy or breastfeeding risks at typical concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
Aminomethyl Propanol
No known risks
An alkanolamine used mainly to adjust product pH. Cosmetic safety reviewers concluded that aminomethyl propanol is safe in current cosmetic use at the reviewed concentrations. Formulators should control secondary-amine impurities and should not combine it with nitrosating agents. No pregnancy-specific concern is identified for normal use of a properly formulated finished cosmetic.

1,2-Hexanediol
No known risks
1,2-Hexanediol is commonly used as a solvent and preservative booster; topical exposure is low and it has no known pregnancy or breastfeeding concerns at cosmetic concentrations, though very sensitive skin may occasionally react.
Sources: CIR; EU/UK Cosmetics Regulation
Caprylyl Glycol
No known risks
Humectant and preservative booster used to support product stability. Low systemic exposure expected from topical cosmetic use.
Sources: Scientific Committee on Consumer Safety (EU); Cosmetic Ingredient Review (US)
Mannitol
No known risks
This sugar or sugar alcohol is used as a humectant and skin-conditioning ingredient. Cosmetic Ingredient Review assessments support these saccharides in current cosmetic use, with no pregnancy- or breastfeeding-specific concern identified for normal topical exposure.

Questions about this assessment
Why does Prequel Lucent-C Brightening Vitamin C Serum have a No known risks rating?
No higher-risk ingredient flags are shown in the assessed entries. Ingredients without a matched rating are marked Not assessed, not No known risks. The product score is a stored assessment, not a clinical safety guarantee.
Does the niacinamide rating cover every ingredient in this product?
No. Niacinamide appears in the recorded formula, but its individual rating applies to that ingredient, not automatically to the whole product. Check the other ingredient ratings, any grey Not assessed entries and the stored product assessment. A niacinamide percentage or a product name is not a substitute for checking the full list.
Has every ingredient in Prequel Lucent-C Brightening Vitamin C Serum been assessed?
14 of 14 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 Prequel Lucent-C Brightening Vitamin C 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.
