Efficacy and safety of hyaluronic acid fillers for lip augmentation in a Chinese population

Abstract

Full lips are considered youthful and attractive. Lip augmentation is one of the most popular cosmetic procedures performed today, especially in Caucasian populations. 1 Previous studies suggested that hyaluronic acid (HA) is an acceptable material for nonsurgical facial rejuvenation. 2 As living standards are improving, Chinese have paid increasing attention on to the facial rejuvenation. A recent consumer survey revealed that there is a gradual increase in Chinese consumer demand for lip augmentation. Regrettably, no injectable HA has been approved for lip augmentation in China till date. Clinical trials of lip augmentation have previously been reportedfor non-Asian subjects. 3,4 However, no study has investigated the effectiveness of HA injection for lip augmentation in the Chinese population. Given esthetic differences, the technique and volume of injections may also differ across different populations. Therefore, the present study aimed to explore an appropriate injection technique that can be applied to Chinese.

Lips enhancement using hyaluronic acid

“…Results showed that HA was well tolerated by patients and safe, with few reported long-term side effects. 5 Other results showed that different hyaluronic acid-based products were effective and safe in improving lip volume and appearance, with an average duration of about nine months. 6 The application is usually well tolerated by patients, with few reported side effects, such as pain, swelling, and bruising at the injection site.…”

“…The results showed that hyaluronic acid enhances lip volume and reduces perioral wrinkles, with a favorable safety profile. 4 In addition, a retrospective chart review study by Guo et al, 5 evaluated the long-term safety of HA for lip fillers in a large sample of patients. Results showed that HA was well tolerated by patients and safe, with few reported long-term side effects.…”
