MamaSkin rates the recorded formula for BYOMA Clarifying Serum as Low risk (78/100). Review the ingredient context and any manual-review explanation before deciding.
The recorded formula includes 3 ingredient entries with risk flags: Gluconolactone (Low risk), Tanacetum Annuum Flower Oil (Low risk), Lactic Acid (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.
26 of 26 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.
How we assess productsThe recorded formula, with evidence behind each rating. Unmatched ingredients are marked Not assessed in grey.
Polyhydroxy acid (PHA) used as a gentle exfoliant/humectant; generally less irritating than AHAs due to lower penetration. Considered safe as used in cosmetics, with no pregnancy-specific contraindications identified at topical cosmetic concentrations.

Blue tansy is Tanacetum annuum, not the thujone-rich common tansy Tanacetum vulgare. Available composition studies describe a variable concentrated essential oil but do not establish a reproductive or developmental hazard from normal topical cosmetic exposure. MamaSkin applies Low Risk for limited pregnancy data and essential-oil sensitisation or composition uncertainty, not as a contraindication.

Endogenous alpha-hydroxy acid and humectant; at modest cosmetic concentrations (≈5% and below, and generally <10%) topical lactic acid is considered compatible with pregnancy. Main risks are local irritation and increased photosensitivity rather than systemic toxicity or fetal effects.

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

Stearic acid is a fatty acid used to stabilise emulsions and improve texture; it is considered low concern in topical cosmetics with no known pregnancy or breastfeeding risks at typical concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
This naturally occurring fatty acid is used for emolliency, cleansing support or texture. The Cosmetic Ingredient Review concluded that assessed fatty acids are safe in current cosmetic use when formulated to be non-irritating and non-sensitizing; some can increase penetration of other formula ingredients.

Zinc lactate is a zinc salt used in cosmetics. CIR includes it in a safe-when-nonirritating assessment of zinc salts; this concerns ordinary topical exposure, not medicinal oral zinc dosing. Direct human pregnancy studies of this exact ingredient were not identified; the rating applies to normal topical cosmetic use.

Polymer thickener used to stabilise emulsions. Large-molecule ingredient with low systemic absorption.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
A high-molecular-weight polymer used to hold water and stabilise texture. Cosmetic safety reviewers concluded that glyceryl acrylate/acrylic acid copolymer is safe in current cosmetic practices. Dermal absorption of the finished polymer is expected to be limited; residual monomers should be controlled by cosmetic manufacturing standards.

Ingredient ratings refreshed 1 October 2026. Formulas vary by market and can change. Always compare with your packaging.
The recorded formula includes 3 ingredient entries with risk flags: Gluconolactone (Low risk), Tanacetum Annuum Flower Oil (Low risk), Lactic Acid (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.
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.
26 of 26 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.
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.
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.
