Essentially, they are proteins secreted by all cell types. They regulate cellular growth, proliferation and differentiation under controlled conditions. They play an important role in maintaining healthy skin structure and function. Growth factors stimulate biochemical pathways that promote skin tissue repair and regeneration. They function the same in the plant world, where they are also known as Cytokinins.
Cytokinins are a class of plant growth substances that promote cell division, or cytokinesis, in plant roots and shoots.
Two powerful types of cytokinins are Kinetin and Zeatin. Both are effective in improving the appearance of ageing skin.
Facts about Cytokinins
- As early as six weeks Kinetin has been shown to reduce the appearance of sun spots and increase the skin’s ability to retain moisture.
- When researching the plant DNA-derived ingredient Kinetin, scientists discovered that this plant-based growth factor prevented plant leaves from drying out and withering.
- Kinetin gently yet effectively helps keep skin looking smooth and radiant.
- Zeatin is RNA-derived from immature corn kernels and occurs naturally in plants.
- Zeatin has been shown to improve skin appearance including roughness, fine lines and wrinkles, and reduce blotchiness after just 12 weeks.
- The Kinetin-Zeatin Complex is transported into the skin by Prosomes, and slowly released over 12 hours to help improve the visible signs of ageing.
- A Prosome is a patent-protected exclusive liposome.
- Prosomes encapsulate nearly twice the amount of ingredients compared to conventional liposomes, delivering unprecedented levels of Kinetin and Zeatin into the skin.
Skincare products that contain Growth Factors
Growth factors in skincare stimulate cell renewal, enhance collagen production for improved skin texture and elasticity, aid in wound healing, and counteract signs of ageing such as wrinkles and sagging skin. They promote skin regeneration and can help achieve a more youthful and rejuvenated appearance. Dr Webster recommends:
