Skin aging occurs when cells lose their ability to divide. At the age of 25, fine lines (and over time wrinkles), age spots and dryness start to appear. Our skin also becomes thinner and loses fat, making it less plump and smooth. Also, aging skin takes longer to heal.
Our skin ages for a variety of reasons– some are inevitable and cannot be changed while others can be prevented or controlled through a holistic approach to skincare. Understanding the factors that affect the skin’s structure and function can help to inform choices about treatment and prevention.
The swiftness by which the skin ages are all due to oxidative stress — a disturbance in the balance between the production of reactive oxygen species (free radicals) and antioxidant defenses. We age due to the accumulation of damage due to free radicals as time goes by. A free radical is a highly volatile atom or molecule that consists of a single unpaired electron in an outer shell. The majority has extensive ability to damage all cell structures including lipids and proteins. Normally free radicals are caught and neutralised by anti-oxidants in the skin, however, over time, the skin’s ability to de-activate free-radicals decreases. The result is damage to all components of the skin cell. Oxidative stress is accelerated and triggered by a variety of lifestyle factors such as sun, pollution, lack of nutrition, smoking habit, and poor skin caring.
The skin has the ability to repair and regenerate with a healthy diet and the right vitamins to support skin growth and wound healing. Since our skin can lose its elasticity over time through age, pollutants in the air and sun exposure, it is important that we consume enough vitamins and minerals and sustain our skin care routine with skin regeneration growth factors to assist and promote the natural functions of the skin.
And, what is growth factor?
It is a naturally occurring substance capable of stimulating cellular growth, proliferation and cellular function. Usually, it is a protein or a steroid hormone, and is important for regulating a variety of cellular processes. There are different growth factors exist that promote skin regeneration such as EGF, FGF, IGF, KGF, VEGF, SCF, and many more.
The cosmetic functions of a growth factor:
- Actively generates new skin cells for anti-wrinkle & antiaging effects
- Replenishes and nourishes the skin texture for a revitalized and whitened skin appearance
- Reduces free radicals and inhibits skin aging through potent antioxidant activities
- Stimulates hair follicles to potentially induce hair growth
- Accelerates wound healing and eliminates scars by forming new cells
Once people pass their 20s, the amount of growth factors in their skin decreases which slows down the speed of cell division and eventually leads to wrinkle formations. The cell regeneration cycle for people in their 20s is about 4 weeks but the cycle increases to at least 6 weeks once people reach their 30s. To prevent aging and to replenish the vanishing growth factors, there is a need to maintain the levels to that of people in their 20s.
