Erythema or reddening of the skin –

This is usually eliminated once the oil mix is removed from the skin. An aloe vera gel can be applied or a soothing lotion to calm the skin. In the future the client should be patch tested before introducing new oils. If the client and you suspect that it is an allergic reaction then that oil/s should be contraindicated for that client. An allergic reaction will be more severe and may present as erythema of the skin and possibly hive lesions on the skin. It is possible to use the same oil for a number of treatments with no reaction and in a subsequent treatment to develop a reaction. It is something that the beauty therapist should be aware of, as it could affect you rather than the client. Regularly changing the blends, ensuring that you limit the number of treatments, and being careful with blending dilutions are all considerations to avoid an allergic skin sensitisation reaction.
