Nasolabial folds, also known as nasolabial folds, are two stripes that extend from both sides of the nose to the corners of the mouth. It is one of the most obvious signs of aging, making people look tired, serious, and even older than their actual age.
In modern medical beauty methods, in addition to using filler to fill nasolabial folds, a minimally invasive method can also be used, that is, Botox. Botox is a widely discussed improvement solution.
This article will use simple language to help you understand how Botox for nasolabial folds works, its advantages and disadvantages, applicable population, risks, care suggestions, and how to ensure effectiveness and safety by choosing the right needle and brand.
What is nasolabial fold?
Nasolabial folds are a natural phenomenon that occurs when the face grows older. When I was young, my skin was full and my collagen was sufficient. The skin on both sides of the nose and the corners of my mouth was tight, and there were almost no obvious traces. But over time:
Collagen loss: The dermis becomes thinner and the skin loses elasticity.
Facial fat sagging: Apple muscle support decreases and nasolabial folds become deeper.
Muscle pulling: The expression muscles are active for a long time, so that the lines gradually fix them.
Dry skin: reduce moisture to increase the obviousness of the lines.
Once the nasolabial folds deepen, they will make people look old and haggard. Therefore, more and more people choose medical beauty methods to improve.
The principle of Botox to improve nasolabial folds
Botox is the main component of Botox, which blocks signals between nerves and muscles and temporarily relaxes the target muscle. For nasolabial folds, the role of Botox is mainly reflected in the following points:
Relax the nose and wing lifting muscles
Excessive contraction of muscles near nasolabial folds will deepen the lines, and the muscles will relax after injection of Botox and reduce the sense of groove.
Assist facial rejuvenation
Botox not only improves dynamic streaks, but can also be used in combination with fillers (such as hyaluronic acid), making the effect more natural.
Minimally invasive, safe, fast recovery
The injection process usually takes more than ten minutes, no surgical incision is required, and the recovery period is short.
However, it should be noted that Botox improves dynamic lines more significantly. If the nasolabial folds are static lines caused by fat sagging and sagging skin, it is necessary to combine fillers or lifting items to achieve the ideal effect.
Advantages of Botox to improve nasolabial folds

Quick operation: Completed in about ten minutes, basically no recovery period.
Fast effect: The effect appears 3-7 days after injection, reaching peak value in about 2 weeks.
Natural adjustment: Relax muscles and will not significantly change the face shape.
Relatively acceptable price: more economical than surgical skinning.
Strong reversibility: The effect of the medicine will gradually fade in about 6 months. If you don’t like the effect, you can wait for natural recovery.
Possible side effects and risks
Although Botox is a mature medical beauty project, it still has certain risks, especially when the injection site is close to the nose and oral wings, the operation requirements are higher:
Local bruises, redness and swelling
There may be mild swelling, needle eye or bruises after injection, which usually resolves on its own in a few days.
Unnatural expression
Excessive dose or inaccurate injection point may cause stiff smiles and limited movement of the corners of the mouth.
Left and left asymmetry
If the dose on both sides is uneven, there may be a situation where the lines are reduced and the lines are obvious on the other side.
Medicinal effect spread
If the injection layer is too deep or the massage is improper, the medication spreads to the adjacent muscles, causing perioral activity to be affected.
Therefore, if you want to improve nasolabial folds safely and effectively, you must choose a professional doctor, a formal institution, and use high-quality needles in conjunction with it.
The importance of choosing the right needle
Botox injection is a fine operation, especially in the nasolabial area, where blood vessels and nerves are densely distributed, and the requirements for needles are higher:
The needle should be fine: A fine needle can reduce pain and reduce the risk of bleeding.
The length should be appropriate: ensure that the drug can reach the target muscle, and avoid spreading if it is too deep.
The syringe must be smooth: low resistance will allow the doctor to more accurately control the injection speed and dosage.
The needles generally used for Botox injection are meso needle or insulin needle, which are both thin and short, allowing the medicine to enter the target area accurately, minimizing trauma and side effects.
