The majority of essential oils can be part of the composition of a personalized perfume. However, some oils pose real risks when used on a daily basis. It is therefore important to take into consideration the contraindications for use before composing a synergy intended for cutaneous application.
Cold pressed citrus zest
Some zests have a high coumarin content. This molecule increases sensitivity to the sun (sensitizing photos). The reaction is then noticed by the appearance of pigment spots on the skin. Bergamot zest is reputed to be the worst of all.
*Certain citrus fruits are less at risk but can still cause a long-term reaction. Distilled peels do not present this same major contraindication.
Oils high in aromatic aldehydes: dermocaustic
Cinnamon bark oils are high in phenols and aromatic aldehydes, families of molecules that are dermocaustic. They can be used in traces to give a warm and comforting aroma to certain preparations.
Oils high in ketones: neurotoxic
Oils high in citrals : dermocaustic
Essential oils rich in citrals, the molecule at the origin of the lemony note, can be irritating to the skin when used on a daily basis.

First aid
In the event that a burning sensation or redness appears following the use of an essential oil, the first step is to dilute with a neutral vegetable oil, then wash with dish soap. In case of contact with the eyes, rinse with a neutral vegetable oil, then with water. Remember that essential oils are not water soluble. |
*Please note that sensitivity varies from person to person and may develop over time. It is recommended to perform an allergy test on the inside of the wrist before applying an essential oil to a large surface.
