Camellia sinensis leaf extract, Kojic acid + 5 more
Works well

This product contains antioxidants (kojic acid, ubiquinone) 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 - camellia sinensis leaf extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Camellia sinensis leaf extractKey activeEffect: MediumCan 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~1.7–2.1%
Kojic acidKey activeEffect: HighHelps to reduce hyperpigmentation and neutralize free radicals. Can be irritating~0.3–0.55%
UbiquinoneKey activeEffect: HighCoenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen~0.25–0.45%
Aesculus hippocastanum seed extractEffect: LowPlant extract. Might have some anti-oxidant properties. Can be irritating~1.4–1.7%
Beta-glucanEffect: LowHelps attract water to the upper layer of the skin, calm down inflammation and irritation, restore the barrier function and support wound healing. It can be helpful in reducing fine lines and wrinkles~0.6–0.9%
Magnesium ascorbyl phosphateEffect: Low, below effective doseA derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high~0.45–0.7%
Butyrospermum parkii butterEffect: Low, below effective doseA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~0.25–0.5%

What the product description says
“Kojic Acid helps control melanin production and prevents hyperpigmentation.”

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

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.

What the product description says
“and fine lines and wrinkles by combating the underlying cause of darkening and aging.”
Source: Skinstore

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: sodium chondroitin sulfate, sodium hyaluronate.

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: glycosaminoglycans, cyclopentasiloxane.

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~5.1–6.2%

Beta-glucanKey activeEffect: HighHelps attract water to the upper layer of the skin, calm down inflammation and irritation, restore the barrier function and support wound healing. It can be helpful in reducing fine lines and wrinkles~0.6–0.9%
