What the product description says
“The following treatment, step two, utilises an intelligent blend of brightening and moisturising actives.”
Source: Mankind

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: helianthus annuus seed oil.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.95–1.4%

Lactic acidUnder-dosedAn 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 microbiome)~0.1–0.45%

What the product description says
“Polish and perfect the complexion with the Erno Laszlo White Marble Dual Phase Vitamin C Peel ; a clarifying, two-step system that exfoliates and brightens the visage.”
Source: Mankind

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.
