Key actives
Anti-blemish
This product can help reduce breakouts and clogged pores because it contains the following ingredient: azelaic acid. This ingredient is used for treating acne and can have a noticeable effect.
In addition, this product contains potassium azeloyl diglycinate. It can help in reducing blemishes, even though it is less effective.
Is produced by a yeast that lives on normal human skin. It is used in medicine as a topical treatment for mild to moderate acne. It has a mild exfoliating effect. It can also help reduce hyperpigmentation, helps calm down inflammation and can help neutralize free radicals
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
A plant extract that can help neutralize free radicals in skin. It contains a compound salicin that can theoretically be converted into salicylic acid that, in turn, helps reduce inflammation in skin, but the evidence of effectiveness in skin is lacking and the extract is usually not used in a concentration that would enable an exfoliating effect
Anti-oxidation
This product contains antioxidants (azelaic acid, glycyrrhetinic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
Active compound of licorice root. Works to calm down inflammation, as an anti-oxidant, and might be helpful in lightening the skin and reducing hyperpigmentation
Is produced by a yeast that lives on normal human skin. It is used in medicine as a topical treatment for mild to moderate acne. It has a mild exfoliating effect. It can also help reduce hyperpigmentation, helps calm down inflammation and can help neutralize free radicals
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals

It contains a compound salicin that can theoretically be converted into salicylic acid that, in turn, helps reduce inflammation in skin, but the evidence of effectiveness in skin is lacking and the extract is usually not used in a concentration that would enable an exfoliating effect
An active component of chamomile plant that historically has been used to calm down irritated skin. A recent study shows that bisabolol indeed can have some anti-inflammatory effect on skin, even though conclusive data is lacking. Bisabolol has a sweet floral scent and can be added to products for its aromatic properties
Being 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.
Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: azelaic acid, potassium azeloyl diglycinate
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycyrrhetinic 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.

Anti-aging
This product contains azelaic acid, glycyrrhetinic acid. These ingredients help neutralize free radicals in skin. By doing so, they might be able to prevent early signs of aging (like fine lines and wrinkles), at least to some extent. These ingredients will not be able to "reverse" signs of aging.

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, butylene glycol.
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: butyrospermum parkii butter, caprylic/capric triglyceride.
