“ExfoliKate Gentle Exfoliating Treatment”
From product name

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: lactic acid.

Lactic acidKey activeEffect: HighAn 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)~3.7–4.6%
PapainEffect: LowAn enzyme extracted from papaya fruit. Can have an exfoliating effect on the skin. Can be irritating~0.6–0.85%
Retinyl palmitateEffect: Low, below effective doseThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.25–0.5%

What the product description says
“Papaya, pineapple and pumpkin enzymes (Kate's 'three Ps for perfect skin') work to counteract dullness, dryness and uneven skin tone and texture by loosening and sloughing away dead, dulling cells to reveal the beautifully balanced, even radiance beneath – without drying.”

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: lactic 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 contains lactic acid. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Lactic acidKey activeEffect: MediumAn 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)~3.7–4.6%
Prunus amygdalus dulcis oilEffect: LowAn emollient that softens the skin~2.4–2.9%
Ascorbyl palmitateEffect: Low, below effective doseBeing a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.~0.3–0.5%

Works

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: lactic acid, honey.

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: sesamum indicum seed oil, cetearyl alcohol.

Lactic acidKey active· HumectantEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid.
