Source: Horace

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide, salicylic acid. These ingredients is used for treating acne and can have a noticeable effect.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: zinc pca

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3.6–4.4%
Salicylic acidHeroEffect: HighUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~1.5–1.9%
Zinc pcaKey activeEffect: MediumA compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing~3.1–3.7%
Anti-aging
Side benefit · Niacinamide, Ascorbyl glucoside + 1 more
Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ascorbyl glucoside.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Ascorbyl glucosideKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.9–2.3%

Exfoliation
Side benefit · Salicylic acid
Works well

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: salicylic acid.

Moisturizing
Side benefit · Niacinamide, Glycerin + 6 more
Works well

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": erythritol, 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).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide, salicylic acid

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: ascorbyl glucoside.

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.

Side benefit · Ascorbyl glucoside, Zinc pca
May help

This product contains antioxidants (ascorbyl glucoside) 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.
