Frown Line Botox and Forehead Botox in Suwon: How Can You Keep Your Brows from Feeling Heavy?

If people say you look angry because vertical "11" lines remain between your brows even when you are not frowning, or if deep horizontal lines form on your forehead every time you raise your brows and it bothers you, it is worth first looking at the muscles that create these wrinkles. Frown line Botox is an injection treatment that reduces the contraction signals of the muscles that draw the brows together and pull them down, easing the movement by which the muscles fold the skin.
Brows feeling heavy after forehead Botox happens when the forehead muscle also loses the strength that supports the brows, so brow height and the habit of using the forehead to open the eyes need to be checked before wrinkle depth. At our Suwon clinic, we look at your expressions with raised brows, frowning, and at rest in turn during the consultation, and then decide the injection points and amount.
This article walks through why frown lines and forehead lines form, why brows can feel heavy, the frown line Botox process, recovery and care, and side effects.
Key Points on Frown Line Botox
- Vertical frown lines are created by the muscles that draw the brows together and pull them down, and horizontal forehead lines by the forehead muscle that raises the brows.
- The forehead muscle creates wrinkles while also lifting the brows, so relaxing it too much at once can make the brows drop.
- Injection height, amount, and points are planned separately so that enough strength remains to support the brows.
- Results last 2 to 3 months on average, and we recommend a schedule of repeat treatment every 3 to 4 months.
Why do frown lines and forehead lines form?
Between the brows, there are muscles that draw the inner brows together and muscles that pull the area between the brows downward. Each time these muscles contract when you frown or concentrate, "11" lines between the brows or horizontal lines above the bridge of the nose form, and with repetition, the lines remain even at rest, giving a tired or angry impression.
The forehead muscle (frontalis) is a thin muscle that covers the entire forehead and creates horizontal lines each time you raise your brows. People who habitually open their eyes wide or who use their forehead to open their eyes because of heavy eyelids use the forehead muscle often, so horizontal lines deepen early.
Wrinkles that appear only with facial expressions tend to fade as muscle movement decreases. Wrinkles that remain deep even at rest mean the skin has already folded and left a mark, so frown line Botox alone may leave some of the line behind.
Why can brows feel heavy after forehead Botox?
The forehead muscle both creates lines and lifts the brows and the skin of the upper eyelids. If this muscle is relaxed a lot all at once, the brows drop, and the lowered brow skin covers the upper eyelid area, making the eyes look smaller or feel heavy.
- If your brows are naturally low or your eyelids are thick, you will feel your brows have dropped more noticeably even with the same amount.
- If you habitually raise your forehead when opening your eyes, your eyelids will feel heavy after the muscle relaxes.
- Injecting into the lower forehead close to the brows, or using a large amount, also reduces the strength that supports the brows.
Relaxing the frown muscles can also cause the inner brows to lift slightly. That is why, when the area between the brows and the forehead are treated on the same day, we look at the balance between the two areas together.

How are frown line Botox and forehead Botox performed?
How Wrinkle Botox Works and Injection Planning
Botulinum toxin blocks the release of the substance (acetylcholine) that carries contraction signals from nerve endings to muscles. Muscles receiving fewer signals move less, and the skin those muscles used to fold folds less as well.
To keep the brows from feeling heavy, it is important not to stop the forehead muscle entirely but to leave enough strength to support the brows. The injection height is centered on the upper forehead well away from the brows; for first-time patients or those with low brows, we start with a small amount; and rather than injecting evenly across the entire forehead, we choose the spots where wrinkles fold deeply. For the area between the brows, the amount is reduced if the inner brows are already drooping.

Recovery and Care After Frown Line Botox
- You can wash your face and wear makeup from 2 to 3 hours later.
- For 3 to 7 days after treatment, avoid heavy drinking, smoking, saunas and Korean bathhouses, hot baths, and strenuous exercise to prevent inflammation.
- Do not rub or irritate the treated area excessively, and avoid intense massage or meridian massage for one month.
- Small raised bumps at the injection sites, often called embossing, subside within 2 to 3 hours and may last about 1 to 2 days depending on skin condition.
The weakening of muscle strength appears over several days rather than right after treatment, so the shape and brow height are judged after the changes have settled. Getting injections in the same area frequently at short intervals can weaken the response to the product, so keeping a record of where and when you were previously treated helps in planning next time.
Side Effects and Precautions for Frown Line Botox and Forehead Botox
Because this is an injection treatment, bruising and swelling may occur depending on skin condition, but they are mild and soon subside. Stinging and redness at the injection sites may also last briefly, and the degree to which the muscles respond varies from person to person, since muscle size and expression habits differ.
You may feel that your brows are heavy or your eyes look smaller, notice a difference in brow height between the left and right, or feel that your expressions are unnatural, and these return to normal as the product's effect wears off. Rarely, headaches, drooping eyelids, or hypersensitivity reactions to the product can occur. If you have previously felt heavy brows after Botox, or if you have medical conditions or take medications, please tell us in advance during the consultation. If you are pregnant or breastfeeding, have a neuromuscular disease such as myasthenia gravis, or have had a hypersensitivity reaction to botulinum toxin, please let us know before treatment.
If one eyelid droops enough to cover the eye, if you see double, or if swallowing or breathing becomes uncomfortable, please contact the clinic right away.
What should be checked before frown line Botox?
If This Sounds Like You, Start with an Assessment of Your Expressions
- "11" lines remain between my brows even at rest.
- I habitually raise my forehead when I open my eyes.
- My brows are naturally low or my eyelids are on the thicker side.
- My brows have felt heavy after forehead Botox before.
If two or more of these apply, it is best to first check your brow height and your habit of using your forehead before deciding on injection points and amount. Whether to have treatment, which method to use, and how wide an area to cover are decided together in consultation after the medical team examines you.
In short, the key with frown line Botox and forehead Botox is to look first at the strength supporting the brows rather than wrinkle depth, and to plan injection height and amount separately.
FAQ
Q. If my brows feel heavy after forehead Botox, how long does it last?
A. It gradually returns over the weeks to months during which the product's effect wears off. At the next treatment, we plan with a higher injection height and a smaller amount, so letting us know during the consultation which areas felt heavy and when helps us plan.
Q. Will frown line Botox alone reduce forehead lines?
A. The frown muscles and the forehead muscle are different muscles, so treating only the area between the brows leaves the horizontal forehead lines as they are. However, for people whose forehead also folds when they frown, relaxing the area between the brows may reduce the lines on the lower forehead, so we discuss both together.
Q. Are frown line Botox and forehead Botox done differently for men?
A. Men tend to have wider foreheads and stronger muscles, so there are more injection points. If the brows are low and straight, more room is left above the brows, and some forehead movement is preserved so that expressions do not look unnatural.
Q. Do frown lines that remain even at rest need filler?
A. If a groove remains even after Botox has reduced the movement, we also consider placing a thin layer of filler in that spot to fill it. Whether the two treatments are done on the same day or separately is decided during the examination based on wrinkle depth and the thickness of the skin between the brows.
Q. Why does frown line Botox seem to wear off faster and faster?
A. How quickly muscle strength returns varies with expression habits and muscle size, and frequent injections at short intervals can weaken the response. Keep to intervals of 3 to 4 months, and the type of product is decided in consultation together with your previous treatment history.
Q. How can I find out the cost of frown line Botox?
A. The cost depends on the number of areas treated and the type of product. We confirm during your consultation which areas, between the brows and the forehead, you want treated together, and then recommend the 1-area or 3-area package. You can also check this on our treatment information page.
