Gold has been used for centuries for its luxurious and decorative properties. More recently, gold has made its way into the skincare and cosmetics industry, with many touting its anti-aging and restorative benefits for the skin. But is there any truth to the claims that gold can improve skin health and appearance? Here we’ll take a look at the evidence behind using gold in skincare.
The Uses of Gold in Skincare
Gold is integrated into skincare products in a few different forms:
- Colloidal gold – Tiny gold nanoparticles suspended in a liquid.
- Gold leaf – Thin sheets of gold that can be used in facials.
- Gold complexes – Gold salts bonded to proteins or other compounds.
These gold ingredients are found in a variety of skincare products:
- Moisturizers
- Serums
- Facial masks
- Eye creams
- Anti-aging creams
The concentration of gold used is typically very low, often less than 1 ppm. The small amount of gold is thought to be enough to provide benefits without causing any toxicity.
Potential Benefits of Gold for Skin
So what are the proposed benefits of using gold in skincare? Here are some of the main claims:
Anti-Inflammatory
Inflammation is implicated in many skin issues like acne, eczema, and signs of aging. Some research indicates that gold nanoparticles can reduce inflammation by inhibiting specific pro-inflammatory proteins and pathways. This anti-inflammatory effect may translate to calmer and healthier skin.
Antioxidant
Environmental stressors like UV radiation and pollution create free radicals that damage skin cells and accelerate aging. Gold nanoparticles exhibit antioxidant activities in lab tests by scavenging these free radicals. This may protect the skin from oxidative stress.
Improves Microcirculation
Some evidence suggests gold particles can stimulate microcirculation in the tiny blood vessels within the skin. Enhanced microcirculation delivers more oxygen and nutrients which may lead to healthier, rejuvenated skin.
Stimulates Collagen
Collagen provides structure and elasticity to the skin. With age, collagen production slows leading to sagging and wrinkles. In vitro studies indicate that gold nanoparticles can stimulate fibroblast cells to generate more collagen. This may improve skin firmness and elasticity.
Antimicrobial
Gold demonstrates antimicrobial properties in laboratory testing. When applied topically, gold particles may help kill acne-causing bacteria. Gold complexes have also shown anti-fungal effects.
Evidence for Gold in Skincare
The use of gold in skincare heavily relies on preliminary laboratory and animal research. There is limited clinical evidence on gold’s efficacy and safety for human skin. However, the research that has been done is generally positive.
Some key studies on gold in skincare include:
Wrinkle Reduction
A 2019 double-blind, placebo-controlled study tested a cosmetic serum containing colloidal gold and other botanical extracts on 45 women with wrinkles. After 12 weeks of use, the gold serum significantly reduced wrinkle depth compared to placebo serum.
Increased Skin Elasticity
In one study, 20 women applied a gel containing gold nanoparticles to one forearm twice daily for 8 weeks. Measurement of the treated skin showed increased elasticity and hydration compared to their untreated forearm.
Faster Wound Healing
Researchers applied colloidal gold droplets to wounds on mice. The gold treatment decreased inflammation and accelerated wound closure and healing compared to untreated wounds.
Improved Skin Texture
A clinical study had subjects apply a gold-peptide complex for 2 months. Standardized photography and analysis found improvements in skin roughness, texture, and appearance after gold treatment.
While these study results seem promising, more large scale, long-term trials are needed to conclusively determine gold’s effects on human skin. Many researchers remain skeptical about nanogold skincare and call for stronger regulation in this area.
Potential Risks and Side Effects
Gold is considered relatively inert and biocompatible, especially at the low levels used in skincare. However, some potential risks need to be considered as well.
Allergic Reactions
Gold can cause allergic contact dermatitis in those with metal allergies. Rashes, itching and swelling can occur. But metal allergies are fairly uncommon. Those with known metal allergies should avoid gold skincare.
Nanoparticle Toxicity
Some worry that nanoparticles like nanogold may be absorbed through the skin into the bloodstream and cause unknown toxicity. More research is needed, but at low concentrations this seems unlikely. Those with cuts, wounds or sensitivities may wish to avoid nanogold products.
Discoloration
Gold creams temporarily tint the skin with a subtle metallic glow. Those seeking discreet skincare may wish to avoid gold products. The gold tint fades after washing.
Overall, when used as directed in low doses, gold appears to be a fairly safe addition to skincare routines for most people. But as with any new product, test a small patch first and discontinue use if any irritation develops.
Is Gold Effective Against Specific Skin Conditions?
Let’s examine if gold lives up to the hype around treating some common skincare concerns:
Wrinkles and Anti-Aging
Some early studies reveal modest improvements in wrinkles and skin elasticity with gold products. More research is needed, but gold shows some promise as an anti-aging ingredient. The antioxidant and potential collagen-boosting effects offer reasonable mechanisms for reducing wrinkles.
Acne and Blemishes
The antimicrobial properties of gold may help inhibit bacteria linked to acne. Gold also exhibits anti-inflammatory effects which could calm inflamed breakouts. However, current research has not conclusively shown that gold improves acne.
Hyperpigmentation
Melanin overproduction leads to age spots and hyperpigmentation. In lab studies, gold nanoparticles have inhibited melanin synthesis. This suggests gold may help reduce sun spots, melasma, and uneven skin tone. But human studies are lacking.
Eczema and Psoriasis
Gold’s anti-inflammatory effect may help inflammatory skin conditions like eczema and psoriasis. In the lab, gold nanoparticles reduced inflammation and levels of inflammatory cytokines. More research on humans is still needed.
Skin Damage and Scars
Some research indicates gold can accelerate wound healing and skin cell regeneration. This may lead to faster healing of damaged skin. More evidence is still required.
Overall the research is too preliminary to draw firm conclusions about gold’s efficacy for these specific conditions. More clinical trials in humans are required.
Types of Gold Skincare Products
