This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: 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~1.3–1.9%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.4–5.1%
CarnitineKey activeEffect: Medium~1–1.45%
GlycoproteinsKey activeEffect: High~0.1–0.45%
CyanocobalaminKey activeEffect: HighCan support skin barrier function and reduce inflammation in skin~0.05–0.25%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.05–0.15%
Corallina officinalis extractKey activeEffect: HighRed algae extract that helps attract water to the upper layer of the skin and might contain antioxidants~0.05–0.25%
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~0.05–0.15%
AdenosineKey activeEffect: MediumMight 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)~0.05–0.2%
Polyglyceryl-10 oleateKey activeEffect: MediumHelps soften the upper layer of the skin~0.05–0.15%

Evens skin tone
Side benefit · Arbutin, Niacinamide + 3 more
Works well

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

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: arbutin.

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.

ArbutinKey activeEffect: MediumBeta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin~2.2–3.2%
NiacinamideKey activeEffect: 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~1.3–1.9%
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~0.05–0.15%

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~0.85–1.3%
Anti-aging
Side benefit · Niacinamide, Adenosine + 3 more
Works well

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: folic acid.

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.

NiacinamideKey activeEffect: 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~1.3–1.9%
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)~0.05–0.2%
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~0.05–0.2%
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~0.1–0.4%
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~0.85–1.3%
Anti-blemish
Side benefit · Niacinamide, Chitosan + 4 more

Side benefit · Arbutin, Glutathione + 11 more
Works well

This product contains antioxidants (glutathione) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Product summary

"Holika Holika - Gold Kiwi Vita C+ Brightening Serum" is effective for: Evens skin tone, Anti-aging, Moisturizing and Anti-blemish

Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.85% - 1.30%) it cannot have a noticeable benefit for the skin.
  • Adenosine 0.05% - 0.20%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
  • Humectants (sodium hyaluronate 0.05% - 0.15% and glycerin 3.40% - 5.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
