I would play with the EOs you have and develop a blend that you like to smell. If the scent is objectionable or too strong, it just won't work for general facial use, even if the EOs are helpful for the skin. For a daily use product, the EO blend you use needs to strike a good balance between appealing scent and helpful benefits.
For example, I personally would avoid tea tree, eucalyptus, and mint in a daily use facial lotion -- they are just too strongly scented for me to want all over my face and they can be irritating if applied close to the eyes. For a spot treatment on a zit or other problem spot, well, okay, I could do that, but not every, every day as a general thing.
Okay, going back to the EOs you have. Pick no more than three EOs. I might play around with palmarosa, rosemary, and clary sage. Rosemary has a strong herbal, camphor scent, so use it with a light hand. Palmarosa is sweeter and more floral. Clary sage is softer than rosemary, but still herbal. I'd start with 1/2 palmarosa, 1/3 clary, and the balance rosemary. So, in a 10 drop blend, I would try about 5 drops palmarosa, 3 or 4 drops clary, and 1-2 drops rosemary.
Put a few drops on a strip of coffee filter or clean plain paper. See what you think right after blending, and at 10 minutes, 1 hour, and 2 hours after blending. Don't over-smell the blend at any one time because your nose will become desensitized to it -- just a whiff or three is plenty. Adjust the proportions to suit your nose. If the clary or rosemary don't work for you in this blend, I'd substitute all purpose lavender for either, if you like lavender.
I agree with the others to use the EO blend at 1/2 to 1% of your lotion recipe. For example, if your recipe is 100 grams, a total of 0.5 to 1 gram of EO would be what you'd add. Keep the scent on the light side for a daily use product.
I just made a light facial lotion a few days ago and added EOs at 1%. The scent in the lotion is distinct but light and it works for me.
