See how lips change at each amount, what's realistic for thin lips, how results settle over two weeks, and what treatment costs. Then try each amount on your own face.
Different lip types and amounts. Drag any slider to compare.
The same face at each amount. Most first treatments are 0.5–1 ml; 2 ml is usually built up over two sessions.
Starting point
Subtle
Hydration and a slightly crisper border. A good first step if you want nobody to notice.
Natural, visible
The most common first treatment: fuller lips that still look like yours.
Fuller
More projection and a defined cupid's bow. Usually staged over two visits so the lips can adapt.
Swelling makes lips look biggest in the first days. Judge your result at two weeks.
Lips look fuller than the final result. Tenderness and pinpoint bruising are normal.
Swelling peaks, sometimes unevenly. Avoid heat, alcohol and hard exercise.
Swelling has gone. This is the time to review your result or plan a top-up.
The filler breaks down slowly. Many people top up every 6–12 months.
Thin lips can change a lot, but not all at once. One syringe usually adds visible volume without changing your lip shape; going further is safer in stages, a few weeks apart, so the tissue can stretch gradually and the result stays natural. If your upper lip mostly disappears when you smile, a lip flip or a combination may suit you better than filler alone.
Definition places small amounts along the lip border for a crisper outline. Volume adds fullness to the body of the lip. Symmetry corrects one side that is fuller than the other. Lip lines around the mouth are often treated with a softer filler or skin booster. Tell your injector which of these you want; the technique and amount differ.
Filler suits people who want more volume, shape or symmetry. A lip flip uses a few units of anti-wrinkle injection to roll the upper lip slightly outward; it shows more lip when you smile but adds no volume and lasts 2–3 months. Filler is not suitable during pregnancy or breastfeeding, with active cold sores or infection near the mouth, or with some autoimmune conditions.
Signs of a poor result: a duck-like upper lip that sticks out past the lower, a ridge or "shelf" above the border, filler that has moved above the lip line, lumps you can see or feel, a bluish tint under the skin, or lips out of proportion with the face. Hyaluronic acid filler can be dissolved with hyaluronidase. Seek urgent care for severe pain, skin that turns white or mottled, or vision changes: these can signal a blocked blood vessel.
Common: swelling, bruising, tenderness and small bumps for a few days. Uncommon: lumps that need massage or dissolving, cold-sore flare-ups, asymmetry. Rare but serious: blocked blood vessels (vascular occlusion), infection, delayed inflammatory reactions. Choose a licensed medical injector who uses approved products and can dissolve filler if needed.
Men usually want restored volume and definition rather than a pout. Lower amounts (often 0.5 ml) placed in the body of the lip keep the result masculine and subtle.
Price per syringe (about 1 ml). Your total depends on how many syringes, the product and the clinic.
