"What it is REN Glycol Lactic Radiance Renewal Mask dramatically improves skin tone and radiance while minimising pore size, reducing congestion, thereby smoothing skin texture and reducing the appearance of fine lines."
WIMJ summary

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.

"Papain from Mexican Papaya gently exfoliates dead cells Skin Types Suitable for all skin types."
WIMJ summary

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.

What does the product description say?
"Alpha Hydroxy Acids."
WIMJ summary

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: glycerin, lactic acid.

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: helianthus annuus seed oil, hippophae rhamnoides oil.

WIMJ summary

This product contains antioxidants (vaccinium macrocarpon seed oil) 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.
