What are forehead wrinkles?
As the name suggests, forehead wrinkles are prominent skin creases that appear on the forehead. As age progresses, many patients tend to experience forehead lines as that region is actively involved in various facial movements like frowning.
What are the causes of forehead wrinkles?
Most of the time, patients will notice the appearance of forehead lines during facial movements. These aesthetic imperfections are classified as dynamic lines which occur due to contractions of muscles underneath the skin. Unfortunately, these dynamic lines get permanently etched on the skin due to ageing. The ageing process of the skin is controlled by 2 major aspects which are intrinsic and extrinsic ageing factors. Intrinsic ageing is caused by genetic signalling which results in the reduction of dermal cell turnover rate. It is also the cause for many skin maintenance processes like desquamation—the regular shedding on old dermal cells—to be halted. Unfortun ...
What is osteoarthritis?
The knee is a prime example of a synovial joint. A healthy knee joint is made of bones that are encased with a layer of tough articular cartilage. This protective cartilage constantly secretes lubricating synovial fluid that is rich in hyaluronic acid (HA) to ensure that the bones glide effortlessly against each other without pain or stiffness. The synovial fluid also maintains the joint health by absorbing any sudden impacts. Unfortunately, years of wear-and-tear caused by various factors like excessive weight, genetics, and participating in physically exerting sports (e.g. tennis) can result in disintegration of the articular cartilage. Hence, there will be decreased production of synovial fluid and the bones may grind against each other excruciatingly. When this happens, patients experience tremendous pain, stiffness, and reduced joint mobility; this condition is known as osteoarthritis.

What are dermal fillers?
Dermal fillers are injectable gel used to correct aesthetic imperfections. Dermal fillers are also known as cosmetic implants, medical devices, and soft tissue fillers. Nowadays, these implants exist in varying concentrations with skin-nourishing ingredients integrated to address countless skin problems—from simple skin rejuvenation to volumising deep-set facial wrinkles—effectively.
How long do dermal fillers last?
The residence time—the time taken for an injected implant to be metabolised and disintegrated into the surrounding tissues—generally depends on the type of filler material used. Collagen-based fillers are bioresorbable and have the shortest residence time compared to other types of fillers at only 3 to 4 months. Hyaluronic acid-based implants are arguably the most popular type of filler on the market due to their biocompatibility, effectiveness, and versatility. These cosmetic implants are processed with various manufac ...
