What the product description says
“Exfoliates and hydrates”
Source: SpaceNK US

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

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).

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~22–33%
Glyceryl stearate seKey activeEffect: MediumUsed to stabilize the product formulations and works as an emollient~0.85–1.25%
Capryloyl glycineKey activeEffect: MediumHelps oil and water mix together, preserve cosmetic products, and attract water to the upper layer of the skin~0.2–0.7%
Saccharomyces/rice ferment filtrateKey active· HumectantEffect: MediumA product of yeast fermentation. Can contain humectants that help attract water to the upper layer of the skin and might help neutralize free oxidants~0.15–0.55%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~4.5–6.7%
Behenyl alcohol· Emollient, OcclusiveEffect: LowNon-drying alcohol that helps water and oil mix together. Also serves as an emollient~0.45–1%
Camellia sinensis leaf extractEffect: LowCan 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~0.2–0.75%
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~0.1–0.45%
Dipotassium glycyrrhizateUnder-dosedA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening~0.1–0.45%
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~0.1–0.4%
Exfoliation
Maris sal
Not delivered
What the product description says
“Enriched with exfoliating Japanese konjac, it works to gently slough away dead skin and decongest the pores for a softer, smoother appearance.”
Source: SpaceNK US

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

Maris salEffect: Low, below effective doseUsed to thicken the product formulation and might help to add minerals to the surface of the skin. It is used in scrubs as a physical exfoliant. Can increase sensitivity to other ingredients if left on the skin or used in high concentration~0.2–0.8%
Anti-oxidation

This product contains antioxidants (camellia sinensis leaf extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
