Is one millilitre (ml) enough? The great lip debate

Confession time, it was not that long ago that I was an injectable customer seeking to gain some fullness in my lips. Not only was I cursed with thin lips and minimal cupids bow, but I had a delightful gummy smile that really affected my confidence to the point I wore a fake smile. Driven by a desire to regain my lost confidence, I asked my husband for the gift of new lips for Christmas, firmly believing that a single millilitre of lip filler would be enough to achieve the perfect balance between beauty and naturalness. Little did I know that this journey would teach me valuable lessons about managing expectations and the importance of a comprehensive treatment plan. Join me as I share my experience and shed light on the realities of lip fillers.

The initial injection

Excitedly, I made my way to the injector, who suggested building upon my lips for a more desirable outcome. However, I brushed off the idea, convinced that a single millilitre of filler would suffice for the next 12-18 months. The initial injection left my lips looking incredible, but that was immediately post procedure with swollen lips and the finished product would take a couple of weeks to be evident, so I knew I might be disappointed. I soon realized that my expectations had surpassed what could realistically be achieved in just one session. It was a humbling moment that taught me the importance of aligning expectations with reality.

Learning the truth

Now, having experienced the ups and downs of lip filler treatments and working in the field myself, I am repeatedly reminded that a millilitre is merely a quarter of a teaspoon. This small quantity alone may not be sufficient to achieve the desired look, especially when considering individual preferences and budget constraints. I now understand the wisdom behind my injector’s words: we must “build” the lips gradually to ensure client satisfaction and create a natural appearance. Patience and a well-planned treatment strategy are key.

The limits of a single session

So, do most people only require a single millilitre of lip filler? The truth is, there are numerous variables at play, including the desired look and individual anatomical characteristics. While a millilitre may be sufficient for some, many individuals will benefit from multiple sessions to reach their lip enhancement goals. A process that should not be rushed and in general I aim for a more natural look in my clients.

Understaning the process

To ensure optimal results and minimize risks, we adhere to a maximum of 1ml of lip filler per session. This limitation accounts for factors such as the body’s healing process and potential complications such as a vascular occlusion caused by compression from excess filler. If additional filler is desired, it’s necessary to wait at least four weeks before scheduling another consultation and treatment, although I prefer clients to wait a few months. This precautionary measure allows for proper evaluation, adequate healing time, and the ability to adjust as needed.


My journey to fuller lips has been one of self-discovery and enlightenment. I have come to understand that lip filler treatments are not a one-size-fits-all solution but a process that requires careful consideration of individual needs and realistic expectations. By embracing the “building” approach and working closely with your injector, clients can achieve lip enhancements that harmonize with their facial features and boost their self-confidence. Remember, it’s not just about the quantity of filler; it’s about the artistry and skill of the practitioner in creating beautiful and natural-looking lips. Outside of this your lips are only one component of your face so other areas may need targeting as part of your longer term goals.
