Melaleuca Alternifolia Leaf Oil
Low RiskAn exact label variant for tea tree essential oil. The SCCS concluded that tea tree oil is safe only in specific defended adult dermal product types and concentrations, excluded aerosolised and sprayable formats, and identified it as a moderate skin sensitiser. MamaSkin therefore classifies it as low risk because safety is formulation- and route-dependent, not because it is a pregnancy contraindication.
