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 ...
What is a hyaluronic acid (HA) injection?
Hyaluronic acid (HA) is a naturally-occurring complex carbohydrate with excellent humectant properties. It is an important cell in the body that helps to moisturise other cells for their optimal performance. Synthetic HA is now a permanent fixture in the aesthetic and medical fields due to its versatility and efficacy. A popular product is hyaluronic acid-based injectable fillers that are formulated to correct various dermal defects such as superficial wrinkles and skin creases. Some brands of HA fillers are also designed with high viscoelasticity and malleability to volumise sunken areas and sculpt facial features (e.g. nose, lips, etc.) and contours (e.g. jawline, etc.).
How is hyaluronic acid filler injected?
Hyaluronic acid filler is meant to be injected intradermally into the problematic areas. It is very important that the patient’s medical history and dermal defects are assessed extensively before the procedure to ensure tha ...
What are fine lines and wrinkles?
Fine lines refer to superficial wrinkles that appear on the skin. Besides the face, these pesky wrinkles can appear on various areas like the decolletage and the back of hands. Fine lines are also known as static lines; they remain etched on the skin even when there is no active muscle movement.
What are the causes of fine lines and wrinkles?
Scientists from University Hospital of Liege have categorised fine wrinkles as atrophic crinkling rhytids, because the severity of superficial wrinkles intensify as skin structure deteriorates. Contrary to dynamic lines that happen when the facial muscles are contracted during active facial expressions, these superficial creases happen due to the inevitable ageing of skin. The skin ageing process is a cumulative result of both biological ageing and external ageing factors. Chronologic ageing, signaled by genetics, causes a severe reduction in the repair and growth of healthy dermal cells like collagen, ...
