Geranium Essential Oil – Possible Skin Issues:

Greener Life Diamond – Bio-Healthy Score => 3 – Possible Skin Issues.

Maximum dermal use level: 17.5%

The International Fragrance Association (IFRA) recommends that geraniol be limited to 5.3%, which translates into 17.5% Geranium oil (about 105 drops per ounce of any other carrier oils) for leave-on products like ointments, creams, and lotions. There is no restriction for body washes, shampoos, soaps, and other wash-off products because the oil does not remain on the skin.

There are 250 natural species and thousands of cultivars and hybrid varieties of the Pelargonium plant family, in the genus Geraniaceae and the most popular ones are Egyptian Geranium, Reunion or the Geranium Bourbon and the Moroccan varieties. Most of the varieties have a similar structure of chemical constituents with Citronellol and Geraniol being the prevalent components.

Using Geranium oil in a concentrated form or beyond the safe level of use might cause adverse skin reactions like mild irritation, sensitization (lower risk), rashes, allergy, irritation of the eyes and contact dermatitis. Geranium oil is non-phototoxic in nature.

The primary chemical constituents that are held responsible for the adverse skin reactions of Geranium oil are citronellal and geraniol, where citronellal is reported to exhibit mild irritant effect along with sporadic sensitization and skin irritation and Geraniol is claimed for skin sensitization.

The safe dermal usage level for this oil is 17.5% by IFRA (International Fragrance Association) and this safety report is based on the 30% Geraniol content, which has a maximum dermal limit of 5.3%.

Research reports reveal the skin irritating effect of Reunion Geranium oil used in an undiluted manner; this oil was slightly irritating when tested on mouse skin; when tested with 5% Bourbon Geranium oil on 100 repeated dermatitis patients, the result was placid with two irritant reactions. It has also been proved that cosmetics with Geranium oil formula have caused dermatitis in hypersensitive individuals.

Always blend Geranium essential oil in carrier oils like Olive oil, Jojoba oil or Coconut oil before using it topically. This is because organic and pure essential oils are extremely concentrated liquid substances that may impair the skin surface, when used in an undiluted form.

Essential oils are recommended only for external use and never ingest essential oils as it can cause serious health hazards. When administering Geranium oil orally in studies,  acute dermal LD50 has been witnessed  in rabbits. This may also cause possible drug interactions with antidiabetic medicines and the enzyme, CYP2B6 inhibiting effect of geraniol causes drug interaction metabolized by CYP2B6.

A recent study has witnessed this by testing alloxan-induced diabetic male rats with Geranium oil for about a month. The level of blood glucose was decreased by glibenclamide and the concentration of hepatic glycogen was significantly augmented.

As there are no evidenced reports on the safety of Geranium oil during pregnancy and lactating, it is safe to avoid this oil for it may have an impact on the hormonal fluctuations during these special moments. It is better to keep away Geranium oil from babies, either as a massage aid or for inhalation as it can harm their sensitive and tender skin.
