I used Eucalyptus Essential oil mixed with sweet almond oil for the first time, & it has caused tiny bumps on my face. They almost look like milia, although I am not sure. There was irritation (itching) after 10mins of application. I let it sit for an hour or so, before I realized it's harming in skin. The oil mixture may have been too concentrated. 4-5 drops of Essential oil and 10-12 of almond. How do I go about reversing the effect on my skin? Please suggest. It has been over 24 hours. I also have melasma and I don't now know if it will affect me in any way.
