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.

What is hyaluronic acid?
Hyaluronic acid (HA) is a complex carbohydrate molecule first discovered in 1930s by scientists Karl Meyer and John Palmer. They isolated HA from the vitreous humor (a jelly-like substance) of cow eyes. A few decades later, HA has been found to be extremely beneficially in treating skin lesions. Nowadays, it is an important must-have ingredient in both cosmetic and pharmaceutical industries.
How does it help the skin?
Though it may sound like a corrosive agent, hyaluronic acid is actually very gentle on the skin. It is found abundantly in various parts of human body as it functions to hydrate other cells and tissues. Skin is made up of tons of different cells like collagen and elastin fibres to provide firmness and elasticity. HA then deeply moisturises these dermal structures, so as to improve their longevity and performance. Skin remains supple and moisturised. Unfortunately, the ageing process slows down the production of these cells. External factors ...
