Is it suitable during pregnancy?

MamaSkin rates the recorded formula for Kiehl's Better Screen UV Serum SPF 50+ Facial Sunscreen With Collagen Peptide as Medium risk (51/100). Discuss the flagged ingredients with a qualified healthcare professional before using this formula during pregnancy.

Why this rating?

The recorded formula includes 4 ingredient entries with risk flags: Butyl Methoxydibenzoylmethane 3% (Medium risk), Homosalate 7% (Medium risk), Octocrylene 7% (Medium risk), plus others listed in the breakdown. These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.

29 of 29 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.

Butyl Methoxydibenzoylmethane 3%

Medium risk

Butyl methoxydibenzoylmethane (avobenzone) is a UVA filter used in sunscreens. Reviews note potential endocrine-related signals for several organic UV filters, but data are often not sufficient to establish endocrine disruption, and systemic exposure depends on formulation and use pattern. Pregnancy-specific human outcome data for topical exposure are limited; the key signal is uncertainty around systemic/endocrine effects rather than a well-defined pregnancy outcome dataset.

Sources: TGA: Safety review of seven active sunscreen ingredients https://www.tga.gov.au/resources/publication/corporate-reports/safety-review-seven-active-sunscreen-ingredients

Homosalate 7%

Medium risk

Homosalate is a UV-B filter. SCCS re-evaluations focused on potential endocrine activity and systemic exposure; while endocrine evidence has been described as inconclusive/equivocal, the ingredient remains under endocrine-disruptor scrutiny and exposure modelling depends on product type and use patterns. Pregnancy-specific human outcome data for topical exposure are limited, so the key signal is endocrine uncertainty plus systemic exposure considerations with frequent, large-area use.

Octocrylene 7%

Medium risk

Octocrylene is a UV filter and photostabiliser used in sunscreens and some daily SPF products. SCCS reviewed endocrine-related evidence and noted some indications of endocrine effects in vivo, but with limitations; systemic exposure is plausible with frequent, large-area use. An additional practical signal is that benzophenone can occur as an impurity/degradation product in some octocrylene-containing products. Pregnancy-specific human outcome data for topical exposure are limited.

Sources: SCCS/1627/21: Octocrylene https://health.ec.europa.eu/publications/octocrylene_en

Ethylhexyl Salicylate 5%

Low risk

Ethylhexyl salicylate (octisalate) is an organic UV-B filter with measurable topical absorption. A CIR review records a rat oral reproductive/developmental study with dose-related post-implantation loss and smaller litters at 80 and 250 mg/kg/day (NOAEL 25 mg/kg/day); those repeated oral doses do not model intact-skin cosmetic exposure. The same review found relatively low human-skin permeability and concluded ethylhexyl salicylate safe in the assessed cosmetic uses. A ToxCast-to-human-exposure comparison found the most sensitive in-vitro endocrine response at about 16.5 micromolar versus about 0.023 micromolar maximal-use human plasma exposure, roughly 700-fold lower. FDA still requests additional sunscreen safety data, and pregnancy-outcome data are limited; MotherToBaby reports no proven increased pregnancy risk. MamaSkin therefore uses Low Risk to surface absorption and the evidence gap without treating remote high-dose animal findings as proof that typical topical use should be avoided.

Questions about this assessment

Why does Kiehl's Better Screen UV Serum SPF 50+ Facial Sunscreen With Collagen Peptide have a Medium risk rating?

The recorded formula includes 4 ingredient entries with risk flags: Butyl Methoxydibenzoylmethane 3% (Medium risk), Homosalate 7% (Medium risk), Octocrylene 7% (Medium risk), plus others listed in the breakdown. 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.

Is the MamaSkin score a measure of SPF or sun protection?

No. The score and risk band describe MamaSkin's pregnancy-focused ingredient screening of this recorded formula. They do not measure SPF, UVA protection, water resistance or whether you have applied enough sunscreen. Use the protection and application instructions on your exact packaging, and review the ingredient flags separately.

Has every ingredient in Kiehl's Better Screen UV Serum SPF 50+ Facial Sunscreen With Collagen Peptide been assessed?

29 of 29 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 Kiehl's Better Screen UV Serum SPF 50+ Facial Sunscreen With Collagen Peptide?

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.
