"Rhonda Allison - Brightening Pigment Tonic" is effective for: Evens skin tone
This product could be helpful for: Moisturizing and Anti-blemish, but its actives are not the most effective or are not well-studied.
Ingredient callouts
This product contains acids (lactic acid 0.50% - 1.20%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
Potassium Azeloyl Diglycinate (1.50% - 2.20%). 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 (aminobutyric acid 0.40% - 0.95%, glycerin 0.95% - 1.45% and thermus thermophillus ferment 1.20% - 1.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
In addition, one of our favorite ingredients for hyperpigmentation, Thermus Thermophilus Ferment, helps to regulate skin temperature and reduce the inflammation response.
This product can help reduce hypepigmentation and even out the skin tone because it contains the following
effective ingredients:
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)
Anti-blemish
This product might be able to help reduce blemishes and clogged pores because it contains potassium azeloyl diglycinate.

Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called
"humectants":
aminobutyric acid, glycerin.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This
is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for
ingredients like dimethicone, squalane, oils and butters).
Has been shown to support wound healing and skin barrier function when used topically in rats. Is likely to be effective in supporting skin's hydration and barrier function, but research for human skin is missing. Might have some anti-aging properties but the research is missing
