What are lip fillers?

So, what are lip fillers? Lip fillers are a popular cosmetic procedure used to enhance the size, shape, and volume of the lips. They involve the injection of dermal fillers into specific areas of the lips. The fillers work by adding volume and contour, resulting in fuller and more plump lips. This non-invasive treatment can also help create a youthful and rejuvenated appearance.

What are they made of?

Have you found yourself wondering, ‘what is lip filler made of?’ Well, it is typically made of a substance called hyaluronic acid. Hyaluronic acid is a naturally occurring compound found in the body, known for its hydrating and volumising properties. The hyaluronic acid used in lip fillers is derived from a synthetic or bio-fermented source. It is a safe and biocompatible material that is gradually broken down by the body over time. Lip fillers made of hyaluronic acid provide a temporary enhancement to the lips, allowing for natural-looking and customisable results.

How are they injected?

Lip fillers are injected using a fine needle or cannula into specific areas of the lips. Before the procedure, a numbing cream or local anesthesia may be applied to minimise discomfort. The injector carefully inserts the needle or cannula into the targeted areas, delivering the lip filler in small amounts. They may massage the lips gently to ensure even distribution and smooth results. The process is typically quick, with minimal downtime. Skilled injectors follow proper techniques to achieve precise placement and desired lip enhancement while prioritising patient safety.

Do lip fillers hurt?

The answer to the question ‘do lip fillers hurt’ can vary from person to person. However, most individuals report only mild discomfort during the procedure. Prior to the injections, a numbing cream or local anesthesia is often applied to minimise any potential pain. Additionally, some lip fillers contain lidocaine, a local anesthetic, which can further reduce discomfort. Skilled injectors are also trained to ensure a gentle and precise technique, making the process as comfortable as possible.

Lip filler aftercare

Can you eat after lip fillers?

It is generally safe to eat after getting lip fillers, but it’s worth keeping a few things in mind. It’s best to wait until the numbing treatment wears off before eating, as eating while still numb can be challenging . Once the numbing treatment has worn off, opt for easy-to-eat foods that won’t require excessive lip movement or cause messiness. We also recommend avoiding very salty or spicy foods, as they may irritate the lips and lead to touching or rubbing, which should be minimised.

Can you smoke after lip fillers?

It is advisable to avoid smoking after lip fillers as smoking can hinder the healing process and potentially increase the risk of complications, such as delayed recovery, increased swelling, and compromised results.

Do lip fillers stay hard?

Lip fillers should not stay hard; they are typically formulated to provide a soft and natural feel. However, individual experiences may vary depending on the specific type of filler used, the injection technique, and how the filler integrates with the surrounding tissues. A qualified practitioner can provide patients with guidance regarding the appropriate choice of filler for their desired outcome.

How long does lip filler swelling last?

How long does bruising last after lip filler? And what about swelling? Well, the duration of swelling and bruising after lip filler injections can vary, but typically, bruising may last for a few days to a week, while swelling can persist for a few days, gradually subsiding within a week or two. However, individual healing responses and aftercare practices can influence the duration of these side effects.
