Lip Fillers Q&A Singapore Everything You Need to Know Dr. Mavis Pak

By Dr Mavis Pak

Lip augmentation stands as a pivotal facet within contemporary dermatological practices, addressing prevalent cosmetic concerns. A popular and minimally invasive method involves using hyaluronic acid (HA) dermal fillers. To achieve the best aesthetic results, it’s essential to have a solid grasp of lip topography, muscular and subcutaneous organisation, and the relevant vascular structures.

This blog post delves into these anatomical aspects, shedding light on changes that occur with ageing. Alongside comprehending the strategic placement of HA fillers, we’ll explore common injection techniques. However, it’s crucial to acknowledge potential lip fillers complications and be well-versed in their management. Building upon this foundation, I will provide a comprehensive guide, incorporating scientific insights, to equip aesthetic practitioners and enthusiasts alike with a deeper understanding of the diverse facets involved in lip augmentation, especially lip fillers, in Singapore.

In my role as a practitioner, I believe the initial key lies in a comprehensive understanding of the patient’s desired outcome for their lips. Whether it’s a plump, fuller look, or simply rejuvenated and hydrated lips with a touch of youthfulness, discerning these preferences is crucial. Interestingly, in the Asian population, the trend often leans towards a more subtle enhancement rather than opting for the prominent, Kylie Jenner-esque fuller lips. To kickstart this dialogue, I frequently encourage patients to share a picture or a snapshot of the lips they envision. This visual aid serves as a valuable reference, aligning our goals and ensuring a tailored approach that harmonises with their unique aesthetic preferences.


1. Types of Lip Fillers:

Lip fillers, predominantly hyaluronic acid (HA) based, lead the charge in cosmetic procedures. Scientific studies, such as those by Dr. Daines et al. (2018) [1], underscore the efficacy and safety of HA fillers, emphasising their biocompatibility and natural integration within tissues. Collagen-based and poly-L-lactic acid fillers options comes with granulomas and nodules and hence has been out of favour [2].


2. Typography and Anatomy:

Understanding the anatomy of the lips is pivotal for achieving optimal outcomes. Studies by Dr. Cooper et al. (2020) [3] offer insights into lip topography, muscular and subcutaneous organisation, and the vascular structures that influence the injection process. A nuanced grasp of these anatomical nuances ensures precision and reduces the risk of complications.


3. Side Effects and Granulomatous Formation:

While lip fillers are generally safe, practitioners must be aware of potential side effects. Scientific literature, such as the work of Dr Nguyen Trinh et al. (2022) [ 4], delves into the occurrence of delayed granulomatous formations. Vigilant injection techniques, sterile practices, and a comprehensive patient assessment can significantly mitigate these risks.


4. Botox Lip Flip:

The Botox lip flip is gaining popularity for those seeking subtle yet impactful changes. Scientific reviews, such as the one by Dr. Teixeira et al (2021) [5], explore the mechanism of action and efficacy of this technique in enhancing the upper lip without the need for fillers. Understanding the science behind this procedure allows practitioners to offer tailored solutions to their clients.


5. Prolonging Results with Cosmetic Products:

Maintaining lip filler results is a shared goal for both practitioners and clients. Recommending scientifically-backed cosmetic products becomes integral. Plastic surgeon, Dr Kay’s lip care product highlights the benefits of specific lip care formulations and sunscreen in preserving the longevity of lip fillers.
