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.).

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, ...
What is Sculptra?
It is an injectable filler powder that is designed and manufactured by Sanofi Aventis, a French multinational pharmaceutical company. This implant is made of a poly-L-lactic acid (PLLA) compound, which is a non-toxic, semi-permanent, and completely synthetic polymer that is renowned for its efficiency and tissue-friendly properties. PLLA is used in various biomedical applications such as suture material, soft-tissue implants, bone plates, and even drug delivery systems. Once implanted in the problematic areas, this biostimulating polymer helps to encourage the production of new and healthy collagen fibres. Sculptra comes as freeze-dried micro particles of poly-L-lactic acid (150 mg), sodium carboxymethylcellulose (90 mg), and mannitol (127.5 mg), which must be reconstituted into a sterile, non-pyrogenic suspension with 5mL of sterile water prior to injecting into areas of concern.
