The causes of eyebrow muscle knots are stress, certain medications, poor sleep, headaches and infections that can affect your facial nerves.
Some conditions might only affect one side of your face like above your left or right eyebrow and others can cause pain around your eyebrows.
Stress is the common cause of eyebrow knots and eyebrow twitching and muscle spasms.
Not getting enough sleep can also cause muscle spasms and twitches including in your eyebrow muscles.
Caffeine and eye strain can also cause muscle knots.
Common reasons for your eyebrows being so low include aging, genetics and loss of support.
As people age the muscles and tissues in our foreheads and brow area lose their elasticity and strength and can cause the eyebrows to sag and even droop and make you look concerned, sad or tired.
Some people also have low eyebrows naturally from genetics.
And a lack of support around your eyebrows such as in the temple area can also cause low eyebrows.
You can often fix low eyebrows somewhat by using a soap brow technique or ABH brow freeze which makes the eyebrows appear more lifted.
The area above the eyebrows is called the forehead.
Your forehead is the upper third of your face and is located between your temples and below your hairline.
Your forehead plays a very important role in your facial expressions and aesthetics.
Other important parts that your forehead consist of include.
The Glabella which is the central part of your forehead and is located between your eyebrows.
Your Glabella is also where the superciliary ridges meet.
The skin of the glabella can also be used to check for dehydration.
The superciliary ridges are the prominences of your frontal bone and are located above your orbital margins and are more prominent in males than females.
The Frontalis muscles are muscles that run vertically and raise your eyebrows.
The corrugator muscles are the muscles that run obliquely and move your eyebrows toward your nose.
Your procerus muscles are the muscles that pull the medial portion of your eyebrows down and also create a horizontal furrow over the bridge of your nose.
And the orbicularis oculi muscles are muscles which lower the entire eyebrow.
