Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itchy red rashes along with bumps over the face seems to be due to
allergic reaction to lavender oil and seems to have caused chemical injury to the skin..
I would suggest you to continue doing cool compresses over the face..
You can also apply
Calamine lotion to soothe the skin..
Take oral anti allergics like
Benadryl or Allegra as it will help in reducing inflammation, redness and itching..
You can apply cooled
aloevera gel over the face as it has anti-inflammatory antibacterial properties as well as lubricate the skin..
You can also splash cold water over the face frequently..
Do not scratch the face when there is itching as it can increase inflammation and pain..
In case if there is still no resolution you can
consult a Dermatologist and get evaluated..
Hope this information helps..
Thanks and regards.
