The hemp seed oil used in cosmetics for its benefits comes from a variety of plant of the species Cannabis Sativa, called "agricultural", "industrial" or "textile" hemp. This variety contains no or extremely little (less than 0.2%) THC, a psychotropic molecule. The hemp seed contains about 30% oil, which can be extracted by three different methods: mechanical (first cold pressing), via an often polluting extraction solvent such as methanol or hexane, and with supercritical fluid (CO2). At Typology, the hemp oil present in the hair and beard fortifying oil comes from the first cold pressing of hemp seeds.
Regarding its biochemical composition, hemp oil contains mostly linoleic acid or omega 6 (45 to 65%) and alpha-linolenic acid or omega 3 (14 to 30%). In cutaneous application, it reinforces the hydrolipidic film, which plays a protective role, in the sense that it maintains the level of hydration of the skin and fights against the external aggressions. Non-comedogenic (index of comedogeneity = 0), it does not block the pores and constitutes also an excellent ally of the mixed skins to fatty, because of its action sebo-regulating.
As seen previously, hemp seed oil for skin and hair sometimes contains traces of THC (tetrahydrocannabinol), but European regulations impose a limit of 0.2%.
No worries then because with such
a low concentration of THC,
hemp seed oil is completely safe
for skin, hair, and even ingestion.
Industrial hemp producers are often subject to strict controls in order to verify that the crops are from low THC varieties.
The cosmetic and indeed very beneficial use of hemp oil does not present any danger to health and there are no contraindications. Pregnant women and young children can use it without risk. However, even if it is anti-oxidant, it is not a tanning oil. Do not apply this product before sun exposure.
In any case, if you have reactive and sensitive skin, it is recommended to perform a skin test beforehand. To do so, apply a small amount of undiluted pure oil to your wrist or the hollow of your arm. If you have a bad reaction within 24 hours, do not use this product.
