Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains lactobionic 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.
A polyhydroxy acid (PHA) that helps shed dead cells from the surface of the skin revealing a smoother, more even skin. PHAs tend to be gentler on the skin compared to AHAs (for example, glycolic acid). It also has hydrating properties and helps attract water to the upper layer of the skin. It can help calm down inflammation in skin and support restoration of the barrier function. It has an anti-oxidant effect as well. It can help reduce fine line, wrinkles and improve skin elasticity
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation
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. 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
Anti-oxidation
This product contains antioxidants (lactobionic acid) 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 japonica flower extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

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

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: lactobionic acid.

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