Thin Lips

What are Thin Lips?
"Thin lips" is a descriptive term, not a medical one. It refers to lips that look slim or flat next to the rest of the face, often with a soft border and little definition around the cupid's bow. Some people have always had slim lips. Others notice them narrowing over the years, as the pink part of the lip loses fullness and the outline softens.
The upper lip, the lower lip or both can be involved, and a little asymmetry is common. Knowing which applies to you shapes the plan, and treatment can help add volume, definition and balance while keeping the look your own.

What Causes Thin Lips
Slim lips tend to be one of two kinds. Some people are born with them. Others develop thinning later, as collagen and hyaluronic acid decline. Thin lips can come from a range of factors, including:
- Genetics: Lip size and shape are often inherited, so if close relatives have slimmer lips, yours may follow.
- Ageing: The body makes less collagen and hyaluronic acid over time, which can leave lips thinner, drier and less defined.
- Sun exposure: UV light can weaken the collagen in the lips, which may leave them thinner and drier.
- Smoking: It can speed up the breakdown of collagen and elastin, and the repeated pursing can add fine lines around the mouth.
- Hormonal changes: The drop in oestrogen after menopause can reduce lip fullness further.
- Dehydration and lifestyle: Poor hydration and nutrition can affect the skin's elasticity and fullness, lips included.
Treatments for Thin Lips at ARTÉ
What suits you depends on why your lips look thin, your anatomy and what you would like to change. Dr. Michelle begins with a consultation, looking at your lips and at the face around them.
Lip Fillers
For thin or dehydrated lips, Lip Filler is a great choice. A hyaluronic acid gel is placed to add volume to lips that are naturally flat or have lost fullness with age. The same visit can define the lip border and cupid's bow or balance the upper and lower lip, and the amount is kept modest so the shape stays natural. If subtle volume and dryness is the main concern, a softer filler can be used such that the shape remains natural with the bonus of added hydration.
Possible side effects: You may notice swelling, tenderness, redness or bruising, which usually eases with time. Cold sores can flare after lip treatment, so tell Dr. Michelle if you are prone to them. A consultation is needed first, and results vary from person to person.
Frequently Asked Questions
Does lip filler hurt?
Most people find it manageable. Numbing cream goes on before the injections, and people usually describe a gentle pressure, sometimes with a light tug or prick, rather than pain. The lips are a sensitive area, so Dr. Michelle works at a pace that keeps you comfortable.
Will my lips look unnatural or overdone?
Not if the plan is right. Lips look natural when placement follows your facial proportions, and heavy-handed when volume is chased at the expense of balance. Dr. Michelle treats conservatively and can build the result gradually across visits if you prefer a softer change.
How much filler will I need?
Most people need a small amount, usually under a millilitre per session, depending on how much enhancement you want and where your lips are starting from. Some prefer to split the treatment over two sessions for a more gradual build.
How long do the results last?
Hyaluronic acid lip fillers often last around six to twelve months, though this varies. Lips move constantly when you speak and eat, so they tend to break filler down a little faster than other areas. Metabolism, sun exposure and lifestyle also play a part, and maintenance visits can keep the result going.
Can the result be undone?
Hyaluronic acid gels can be broken down with hyaluronidase, an enzyme, should you want a change. That is reassuring for first-time patients, and it is one reason this type of filler is widely used for lips.
Is there downtime?
Downtime is minimal. The appointment often takes 15 to 30 minutes, and most people are back to their routine that day. Some swelling and tenderness early on is common, and Dr. Michelle will give you aftercare guidance before you leave.
Are lip fillers safe?
In the hands of a qualified doctor who knows lip anatomy, they are generally well tolerated. Serious complications, such as filler entering a blood vessel, are rare but possible, which is why a medical clinic and an experienced doctor matter so much for this treatment.
Why Choose ARTÉ by Dr. M for Thin Lips?
Doctor-Led Care
Dr. Michelle Ng personally carries out every consultation and treatment, and nothing is passed on to another practitioner. Having practised aesthetic medicine for over a decade, she brings close knowledge of lip anatomy and facial proportion to a small, delicate area.
A Plan for Your Kind of Lips
Lips that have always been slim, lips that have thinned with age and lips that are uneven from side to side are different starting points. Dr. Michelle first assesses your lip shape, facial proportions and goals, then plans the amount, the placement and whether other areas of the face belong in the plan.
Natural-Looking Results
The intention is lips that read as part of your own features, not something added on. Treatment is conservative and can be built up in small steps, so the result stays in proportion and looks like you.
Safety-First Approach
You begin with a consultation and leave with clear aftercare guidance. Hyaluronidase is kept on hand at the clinic in case a correction is ever needed.
