What the product description says

“Formulated with 56 essential elements and nutrients, this anti-aging face cream provides intense hydration and nourishment as it firms, lightens and strengthens skin.”

Source: LovelySkin

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: aspartic acid, folic acid, serine, threonine.

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.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.3–0.55%

SerineKey activeEffect: MediumAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.3–0.55%

ThreonineKey activeEffect: MediumAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.3–0.55%

Aspartic acidKey activeEffect: MediumAn amino-acid that helps increase skin hydration and might help to slightly improve skin firmness, potentially reducing lines and wrinkles~0.3–0.55%

Folic acidKey activeEffect: MediumCan help stimulate collagen production in skin. While available studies are promising, more research is needed to confirm the efficacy in skin~0.25–0.5%

HydroxyprolineEffect: LowIs helpful in restoring skin barrier function supporting its moisture levels. Is claimed to stimulte collagen production in skin but evidence is lacking~0.3–0.55%

Ascorbyl palmitateEffect: Low, below effective doseBeing a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.~0.25–0.5%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.15–0.3%

Ascorbic acidUnder-dosedThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.3–0.55%

NiacinUnder-dosedA form of vitamin B3. It is similar in action to niacinamide, but is more likely to cause red flashes in skin as the side effect~0.25–0.45%

NiacinamideUnder-dosedIs 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~0.2–0.4%

Evens skin tone

What the product description says

“You’ll see a vibrant, radiant glow as this cream works to stimulate cellular turnover and lighten dark spots.”

Source: LovelySkin

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glutathione

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: alanine, cysteine, ethyl linoleate.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

GlutathioneKey activeEffect: HighA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin~0.3–0.55%

AlanineEffect: LowAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~0.3–0.55%

Ethyl linoleateEffect: LowHelps reduce acne and blemishes. Helps to soften the upper layer of the skin and reduce inflammation. Might be helpful in reducing hyperpigmentation and evening out the skin tone, but evidence of effectiveness in skin are lacking~0.3–0.6%

CysteineEffect: LowMight help neutralize free radicals in skin and might be helpful against hyperpigmentation~0.3–0.55%

NiacinUnder-dosedA form of vitamin B3. It is similar in action to niacinamide, but is more likely to cause red flashes in skin as the side effect~0.25–0.45%

What the product description says

“Formulated with 56 essential elements and nutrients, this anti-aging face cream provides intense hydration and nourishment as it firms, lightens and strengthens skin.”

Source: LovelySkin

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: alanine, arginine.

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, caprylic/capric triglyceride.
