Product Summary
"Ren Skincare - Mini Ready Steady Glow AHA Toner" is effective for: Exfoliation and Evens skin tone
This product could be helpful for: Moisturizing, Anti-aging and Anti-blemish, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Exfoliating acids (lactic acid 3.40% - 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 (2.10% - 3.10%). 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.
- Humectants (glycerin 0.20% - 0.70%, lactobacillus ferment 2.70% - 4.00% and lactic acid 3.40% - 5.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Evens skin tone
What does the product description say?
Its lactic acid and willow bark extract work together to visibly smooth and tone skin as well as reduce the look of pores while azelaic acid visibly brightens and lightens the appearance of hyperpigmentation.
Source: Sephora CA
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)

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.

A plant extract that might contain salicylic acid
Anti-aging
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.

Moisturizing
What does the product description say?
What it is A toner that exfoliates, visibly brightens and tightens, and hydrates for a smooth, even-, and energized-looking complexion with a fresh, cucumber scent.

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: cocos nucifera fruit extract.
An emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic
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)
A non-living ingredient made by fermentation with the bacteria Lactobacillus. It can help attract water to the upper layer of the skin and might help reduce inflammation
A fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

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.

A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
Might be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect
