The skin barrier typically forms in utero during the third trimester. Therefore, the skin of a newborn is structurally and functionally immature. It is sensitive, thin, and fragile, prone to increased water loss, highly vulnerable to trauma and bacteria, due to a epidermal permeability that facilitates the penetration of foreign substances and the immaturity of drug metabolising systems. This passage is even easier in preterm babies due to their thinner horny layer. Applying oil to a newborn could therefore expose them to a risk of toxicity.
An important consideration is the choice of vegetable oil used. Indeed, studies have shown that certain unsaturated fatty acids such as oleic acid can increase, when present in large quantities, the already significant skin permeability in babies by forming a lipid domain with the lipids of the stratum corneum, and thus lead to contact dermatitis, as it facilitates the entry of potential allergens.
Camelina oil contains very little oleic acid (16% of total fatty acids) compared to other oils (77% in hazelnut oil). It is non-comedogenic and can generally be used safely according to the report on camelina oil by the FDA (Food and Drug Administration).
Furthermore, it does not present any specific contraindications for its topical use. Although no studies have been conducted in the context of topical application on babies, and there are no clear recommendations, it can be assumed that it poses no risk when used on infants. However, it is still necessary to adhere to usage precautions.
Camelina oil is susceptible to oxidative degradation, due to its chemical structure rich in omega-3 double bonds. To maintain its quality, remember to tightly seal the bottle to prevent the presence of oxygen. Store it in a cool place, away from direct sunlight for proper and risk-free preservation against oxidation.
It is advisable to perform a skin test on a small area in the crook of the elbow, on the inner side of the wrist or behind the ear before definitive use to check for potential allergic reactions.
If your baby has specific medical conditions or if there is any doubt, it is recommended to consult a healthcare professional before use.
