The source material does not mention pregnancy or breastfeeding restrictions. However, as a leave-on cosmetic applied to the thin, highly vascularised skin around the eyes, a few ingredients warrant a conversation with your midwife, GP, or dermatologist: orange essential oil (even at low concentrations, some clinicians advise limiting essential oil exposure during pregnancy), placenta extract (animal-derived, though widely used in cosmetics), and the overall penetration-enhancing nature of an occlusive mask format.
General cosmetic safety guidance: if you are pregnant, breastfeeding, have a chronic skin condition, or are on prescription topical or systemic medication, consult a specialist before introducing new active skincare. A patch test (see the sensitive-skin FAQ) is especially prudent during pregnancy when skin reactivity can change unpredictably.
If you prefer to avoid essential oils entirely during this period, look for a fragrance-free eye mask with similar hydrating actives (hyaluronic acid, ceramides, panthenol) and resume this product post-partum if desired.
