What does the product description say?
"Designed to refine pores, reduce breakouts and blackheads while lightening dark spots and blemish marks, the serum gets to work while you’re sleeping so you wake up to the skin you’ve been dreaming of."
WIMJ summary

This product contains ingredients (gluconolactone, glycolic acid) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.

WIMJ summary

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: centella asiatica leaf extract, pentapeptide-59.

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.

WIMJ summary

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

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: glycyrrhiza glabra root extract, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane.

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.

"The hydrating serum is formulated with an acid blend of glycolic, lactic, pyruvic, BHA and PHA, as well as nourishing probiotics, niacinamide and tamanu oil."
WIMJ summary

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: gluconolactone, glycolic acid.

WIMJ summary

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

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).

WIMJ summary

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

The following ingredients - gluconolactone, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Ingredients by volume

Ingredient Estimated concentration
Plain old water
45% - 55%
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
5.9% - 7.2%
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
4% - 4.8%
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
3.1% - 3.8%
2.4% - 2.9%
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
1.8% - 2.2%
Acts as a solvent for other ingredients. Speeds up the absorption of other ingredients into the skin
1.6% - 2%
Used to adjust the product's pH
1.4% - 1.7%
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiom)
1.2% - 1.4%
A fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative
0.95% - 1.15%
0.7% - 1%
An active component of chamomile plant that historically has been used to calm down irritated skin. A recent study shows that bisabolol indeed can have some anti-inflammatory effect on skin, even though conclusive data is lacking. Bisabolol has a sweet floral scent and can be added to products for its aromatic properties
0.5% - 0.75%
A great emollient. Contains vitamin E (tocopherol) which may give it some anti-oxidant properties. Can contain volatile compounds and can be irritating
0.55% - 0.8%
A preservative that comes from radishes fermented by a bacteria. New research suggests that the preservation properties in the ingredient come from an ammonium salt that is not present naturally in radish root but used in its cultivation. Is problematic because the exact amount of the preservative agents is difficult to determine
0.45% - 0.7%
Is 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
0.4% - 0.65%
A plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. It can be irritating to sensitive skin. Might be helpful in preventing stretch marks. It could, however, itself be irritating.
0.4% - 0.6%
Used for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)
0.35% - 0.6%
Naturally present in skin and helps to attract water to its upper layer
0.3% - 0.6%
A plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals
0.25% - 0.5%
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
0.3% - 0.5%
A plant extract that can help neutralize free radicals and reduce inflammation, even though it is not usually used in sufficient concentration in cosmetics
0.25% - 0.45%
An anti-oxidant derived from curcumin (naturally present in tumeric). Is a part of the tetrahydrocurcuminoids complex (THC). The complex might be helpful in neutralizing free radicals in skin and possibly help even out the skin tone. Can be irritating
