What the product description says
“Rich texture wraps the skin without any feeling of stickiness and penetrates the skin quickly and deeply to leave it feeling moisturized and refreshed.”
Source: Yesstyle

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: arginine, betaine.

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: arginine, dimethicone.

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

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~0.45–1.1%
Copper tripeptide-1HeroEffect: HighA naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.~0.05–0.2%

What the product description says
“An anti-aging serum with 2.4 million narcissus plant cells to give skin firmness and radiance.”
Source: Yesstyle

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: copper tripeptide-1, lysine.

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.

It accelerates wound-healing of the skin and can stimulate hair growth.

Product summary

"HERA - Signia Luminesource Radiance Firming Serum" is effective for: Anti-aging and Moisturizing

Ingredient callouts

  • Peptides (copper tripeptide-1 0.05% - 0.20%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
  • Adenosine 0.05% - 0.10%. 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).
  • Humectants (histidine 0.05% - 0.20%, biosaccharide gum-1 0.05% - 0.15%, sodium hyaluronate 0.05% - 0.15%, glycerin 0.10% - 0.35% and betaine 2.20% - 3.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
