The Most Coveted Skincare Ingredient
Adored by the beauty professionals and experts who are forever searching for the next best things, Gold certainly makes a big wave in the beauty industry. As precious as it is, Gold is indeed the most coveted skincare ingredient among those in the know.
What is Colloidal Gold?
Colloidal Gold is a suspension of nanoparticles of gold in a fluid, usually water. Nanoparticle is a particle with size ranges from 1 to 100 nanometer. 1 nanometer is equivalent to 0.000000001 meter.
Why Colloidal Gold is Great for Your Skin?
Colloidal gold is scientifically known to have antioxidant, anti-inflammatory and wound healing properties.
A clinical study showed that gold nanoparticles are capable of penetrating deeper into the skin, therefore, it is likely to further enhance their therapeutic effects. Several studies showed that gold nanoparticles can be used in the treatment of cancers and wound healing.
The Benefits of using Gold Infused Skincare Products
The Antioxidant Benefits of Nanoparticle Gold
Free radicals are free molecules that react with oxygen and trigger the formation of Reactive Oxygen Species. Large amount of Reactive Oxygen Species in the body is the main cause of Oxidative Stress. Oxidative Stress causes damage to skin cells including proteins, lipids and DNA damage. These kinds of damages accelerate the skin ageing process. In addition to that, DNA damage can lead to skin cancer.
The ability of Gold nanoparticles to prevent the formation of Reactive Oxygen Species helps prevent and reduce premature skin damage. Therefore using Gold infused skincare products can help slow down the appearance of signs of ageing. Compared to L-ascorbic acid, the most potent form of vitamin C; Colloidal Gold provides longer-lasting antioxidant skin benefits. Gold nanoparticles are not prone to oxidation upon a contact with water.
The Anti-inflammatory Benefits of Nanoparticle Gold
Chronic skin inflammation is the main cause of premature skin damage. Exposure to UV radiation is known to accelerate skin ageing. This is largely due to the fact that UV radiation triggers skin inflammation that often continues even after the skin is no longer exposed to UV rays.
Inflammatory ageing has been the subject of countless studies. Scientists are still trying to understand the exact mechanism. Chronic inflammation has been associated with many diseases including various type of cancers, heart diseases, Alzheimer's, arthritis and premature ageing.
The anti-inflammatory effects of Gold nanoparticles are beneficial for all skin types, particularly sensitive, environmentally-stress, ageing and premature ageing skin.
Daily use of Gold-infused skincare products like 24k Gold & Rosehip Rejuvenating Cream help your skin fight the damaging effects of daily pollution and stress. This ultra moisturising cream has been formulated with 24-karat Gold nanoparticles (Colloidal Gold) and Rosehip oil to soothe and rejuvenate dry, mature sensitive skin. While the shea butter and rice bran oil contents help lock in moisture and reduce the appearance of lines and wrinkles. The embodiment of true natural beauty in a twenty-first century formula; this rich, luxurious moisturiser leaves skin looking smoother, firmer and revived.
The Skin Renewal Benefits of Nanoparticle Gold
Several studies in Nanomedicine highlighted the potential key role of gold nanoparticles in the wound healing process. Gold nanoparticles were shown to help the delivery of nutrients and oxygen to injured cells, hence, they accelerates the skin's healing process.
The skin renewal benefits of Gold skincare products help slow down the appearance of signs of ageing including wrinkles, lines, sagging skin and loss of elasticity. They also strengthen skin barrier function that help lower the risk of irritation on sensitive skin.
Last but not least, daily use of gold infused skincare products help even out skin tone and boost skin radiance.
