“If I start, will I have to keep having it done?” “If I stop, will my face look worse than before?” These are some of the common concerns about injectable treatments such as botulinum toxin, fillers, or skin rejuvenation injections. These questions are entirely reasonable and deserve honest answers.
This is a topic Dr. Fulya Koç often answers on social media too, and here we look at it in the light of scientific knowledge.
Why Are the Effects of Injectable Treatments Temporary?
The great majority of injection treatments used in medical aesthetics are made with substances that the body breaks down over time or whose effect fades on its own. This is actually not a disadvantage but a safety feature: because the effect of the treatment diminishes with time, the face can adapt to its changing structure with age.
- Botulinum toxin: It temporarily reduces the transmission between nerve and muscle. Its effect usually lasts a few months and wears off on its own.
- Hyaluronic acid fillers: They are similar in structure to a substance naturally present in the body and are broken down over time. The duration varies with the product used, the area, and the person’s metabolism.
- Biorevitalization treatments: The effect of treatments such as mesotherapy and skin rejuvenation injections fades over time within the skin’s renewal cycle.
Will I Look Worse When I Stop?
This is among the most common concerns. The scientific data available do not show that stopping treatments such as botulinum toxin or hyaluronic acid speeds up aging. When the effect wears off, the face returns to its own natural course.
There is, however, a point that should not be overlooked: aging naturally continues during the time you are having treatments too. So when the effect has fully worn off, your face will not look the way it did a few years ago but will look close to the natural state for your age on that day. Because some people get used to the more rested look, they may perceive this return as “getting worse”; yet this is not a negative effect of the procedure but a change from the look you had become used to.
Is It Addictive?
Injectable aesthetic procedures do not create a physiological dependence. The body does not “get used to” these treatments and become unable to function without them. The need to repeat comes not from the substance being addictive but from its effect naturally fading.
That said, for some people the wish to correct every small change with a new procedure can turn into a psychological cycle. This is where the physician’s role matters: separating what is truly necessary from what is not, and being able to say “you do not need this right now” when appropriate.
How Often Does It Need to Be Repeated?
The repeat interval varies with the type of treatment, the dose and product used, the area treated, and the person’s individual characteristics. Lifestyle is also a factor: things like heavy sun exposure, smoking, and a fast metabolism can shorten how long the effect lasts.
What matters is that repeating is seen not as an obligation but as a decision made according to the person’s wishes and needs. Many people can lengthen the intervals after the first treatments, or may prefer to continue with preventive steps only.
A Long-Term Plan Instead of Constant Procedures
According to Dr. Fulya Koç, age management is not a string of unconnected procedures but the step-by-step implementation of a long-term plan. At the center of this plan is protecting the skin’s own capacity:
- Daily sun protection and the right skincare routine,
- Lifestyle habits such as sleep, nutrition, and stress management,
- Biostimulation approaches that aim to support the skin’s own collagen production,
- Injection treatments at measured doses, when necessary, aiming for a natural result.
With this holistic view, the need for injectable treatments can often decrease and the time between treatments can lengthen. Confidence sometimes means doing fewer procedures.
The Right Timing and a Measured Dose
One of the keys to injectable treatments looking natural over the long term is a measured dose and the right timing. Treatments repeated before the effect has worn off, or doses higher than necessary, can change the face’s natural expression. For botulinum toxin, this also matters in terms of the development of antibodies, which can, though rarely, lead to a reduced effect.
For this reason, before each new treatment, the state of the previous procedure’s effect, the person’s satisfaction, and their expectations are reassessed. Sometimes the appropriate recommendation is to postpone the next treatment or to continue only with steps that support skin quality.
Is Starting Early a Must?
Starting injectable treatments at an early age does not mean fewer procedures will be needed later. At a young age, what matters most is sun protection, healthy lifestyle habits, and protecting the skin’s own capacity. Medical treatments, regardless of age, should be planned when there is a real need and after an examination.
Risks and Points to Note
With any injection treatment, temporary side effects such as bruising, redness, swelling, and tenderness may occur. Rarely, more serious complications specific to the treatment can also develop; for this reason it is important that procedures are performed by a physician under suitable conditions.
Pregnancy, breastfeeding, an active infection, some neuromuscular and autoimmune diseases, and the use of certain medications may mean the treatment needs to be postponed or not performed at all.
The Decision Is Yours, the Information Is Shared
Whether to have injectable treatments, how often to repeat them, or whether to stop altogether is your decision. To make that decision in a healthy way, an examination in which you can openly discuss your skin’s condition, your expectations, and the options may be the first step in deciding together on the path that suits you.
