Product Summary
"Ren Skincare - The Radiance Night Time Duo" is effective for: Anti-inflammatory, Exfoliation, Evens skin tone and Moisturizing
This moisturizer could be helpful for: Anti-aging and Anti-blemish, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Exfoliating acids (lactic acid 4.20% - 5.10%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run. Lactic Acid can also help to attract water to the upper layer (works as a humectant).
- Potassium Azeloyl Diglycinate (2.30% - 2.80%). It is a derivative of Azelaic Acid. It is less studied than Azelaic Acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium Azeloyl Diglycinate is better soluble in water compared with Azelaic Acid. Because of this property, products with Potassium Azeloyl Digclycinate can have a nicer texture.

Evens skin tone
What does the product description say?
Encapsulated Algae Complex helps to brighten the look of dark spots while Phyto Glycogen lends a smooth, radiant finish.

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: lactic acid, potassium azeloyl diglycinate
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.
A derivative of azelaic acid. It is obtained by reacting the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium azeloyl diglycinate is better soluble in water compared with azelaic acid. Because of this property, products with potassium azeloyl digclycinate can have a nicer texture
An 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)
Exfoliation
What does the product description say?
This toning lotion gently exfoliates dead skin cells to reveal a smooth, radiant complexion.

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.

Moisturizing
What does the product description say?

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:
arginine, glycerin.
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: arginine, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.
