What the product description says

“Enriched with 24K gold and caviar extracts, royal jelly, hyaluronic acid and EGF (epidermal growth factor,) this luxurious cream helps moisturize, brighten and improve skin elasticity.”

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: betaine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: butyrospermum parkii butter, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, oligopeptide-1

Oligopeptide-1HeroEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.2–0.35%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2.4–2.9%

Hydrolyzed collagenKey active· Humectant, EmollientEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~0.35–0.6%

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.9–2.3%

Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~0.3–0.55%

CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~3.1–3.8%

Macadamia ternifolia seed oilKey active· EmollientEffect: MediumPlant oil from nuts that helps soften the upper layer of the skin. Contains a high concentration of oleic acid that can weaken skin's barrier function and increase water-loss while enhancing penetration of other ingredients~0.75–1.1%

Anti-aging

Not advertised by the brand · 6 ingredients credited for this claim

Strong support

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: oligopeptide-1.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Sodium ascorbyl phosphateEffect: Low, below effective doseA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.15–0.25%

Evens skin tone

Product summary

Based on the ingredients included, "Secret Key - 24K Gold Premium First Cream" works well for moisturizing the skin. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (betaine, glycerin, hydrolyzed collagen, sodium hyaluronate and royal jelly extract) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Astrocaryum murumuru seed butter, hydrolyzed collagen, butyrospermum parkii butter, dimethicone and simmondsia chinensis seed oil in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

We particularly like that there is a good concentration of Niacinamide (1.90% - 2.30%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and help improve the skin tone, reducing pigmentation marks.
This moisturizer also contains Peptides (oligopeptide-1 0.20% - 0.35%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that they are helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
Adenosine 0.25% - 0.40%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: lecithin, agran oil, sodium ascorbyl phosphate and stearic acid

Irritation risk

This moisturizer contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here
