Growth factors and Platelet Rich Plasma are vital to maintaining a youthful appearance. The skin and scalp contain multiple growth factors that regulate natural cellular renewal and maintain a normal hair growth cycle.

Growth factors are responsible for helping to reverse the visible effects of  premature aging due to environmental factors.

Microneedling is a skin rejuvenation treatment that offers a solution for a variety of skin conditions and concerns. Adding epidermal growth factors contained within the PRP, is the most comprehensive and advanced microneedling treatment available.

What are Growth Factors?

Growth factors are a group of specialized proteins found in many different cell types within the body. Their job is to turn essential activities within the cell ‘on’ or ‘off’ to help each cell function as it had in its prime. Playing a variety of roles, growth factors help to maintain the skin’s youthful appearance by increasing cell renewal, cell defense, blood circulation and collagen and elastin production.


The consequences of environmental exposure is excessive free radical damage of skin and scalps cellular components. This results in the breakdown of collagen and elastin networks in the dermis causing visible facial aging.

In multiple studies, topically applied Growth Factors  have been shown to reduce the signs of aging, reducting fine lines and wrinkles by increasing dermal collagen synthesis. Also shortened healing time of burn scars and restored normal hair growth have been outcomes.

In Short What Growth Factors do:

  • Promote improved conditions for healing with reduced inflammation
  • Signals naturally occurring peptide and protein molecules
  • Control cellular growth, proliferation, healing and differentiation

PRP – Platelet Rich Plasma

PRP is concentrated blood plasma that is enriched with platelet cell fragments that contain 8 potent growth factors along with other cytokines which stimulate the healing of soft tissue. In the body platelets are responsible for helping the blood clot and they help rebuild damaged tissue. Externally, studies have shown that platelets can stimulate your stem cells resulting in the growth of new skin.

When Platelet Rich Plasma is used for skin rejuvenation, PRP releases growth factors into the skin to expedite the body’s own repair process and stimulate new collagen and elastin.


When PRP is used in conjunction with microneedling in the scalp it will release growth factors that stimulate hair formation resulting in thicker follicles at a higher density.
