Collagen is a protein that provides structural support to the skin. It accounts for 30 percent of your body’s protein, and is the primary building block of skin, muscles, tendon, ligaments and other connective tissues. In respect to the skin it provides strength, elasticity and firmness. Collagen is abundant in young skin, providing smooth plump and wrinkle free skin. As part of the normal ageing process, natural collagen production begins to slow down. From our mid 20s, collagen production decreases by about 1% per year, this is known as intrinsic ageing, with genetic factors playing a significant role.

External factors can also accelerate the process and include

  • Sun Exposure & UV
  • radiation
  • Smoking
  • Poor Diet and Nutrition
  • Environmental Toxins


Loss of collagen contributes to visible signs of ageing and the effects include:

  • Fine Lines and Wrinkles
  • Loss of skin laxity and
  • sagging skin
  • Skin thinning
  • Uneven texture

They are designed to stimulate the body’s natural collagen production, and is used to reduce the appearance of wrinkles, fine lines and loss of volume. Due to Australian TGA regulations, we are unable to name the brand of collagen stimulator that we use. The bio-stimulator used at Kaya Cosmedica in South Melbourne is composed of a calcium microspheres (similar to minerals naturally found in the body) suspended in a water based gel. This product is preferred by Dr PK as it has dual actions – it not only provides immediate results with volumisation, but also stimulates production of and is completely replaced by the body’s natural collagen over time – leading to longer lasting benefits in skin quality and texture for up to 18 months.
