What the product description says
“20% Niacinamide (Vitamin B3): minimizes enlarged pores, improves uneven skin tone and promotes a smooth, blemish-free complexion”
Source: Dermstore

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient 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: epigallocatechin gallate

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~4.8–7.2%
Epigallocatechin gallateKey activeEffect: MediumA polyphenol found in tea. This particular compound abbreviated EGCG is the most powerful antioxidant among those extracted from tea (usually green tea). Unfortunately, EGCG is unstable, requires a low pH (below 4) to prevent quick degradation, and does not penetrate the skin very well. This is why the full anti-oxidant effect of EGCG is typically not realized when it is added to topical skincare~0.4–0.9%
Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.35–0.8%
AllantoinEffect: Low, below effective doseHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.2–0.75%

What the product description says
“Sol de Janeiro bring you a nourishing, moisture-rich cream designed to boost the skin’s elasticity.”
Source: SpaceNK

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

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: acetyl glucosamine, niacinamide

What the product description says
“This serum uses a safe and effective concentration of niacinamide (vitamin B3), specifically chosen to help normalise pore function, working to improve the look of sagging skin and defending against damage from harmful UV light.”
Source: SpaceNK

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

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

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.

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~1.5–2.2%

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

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, epigallocatechin gallate, glycyrrhiza glabra root extract.

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.

Product summary

"Paula's choice - Niacinamide 20% Treatment" is effective for: Anti-aging, Moisturizing, Evens skin tone and Anti-blemish

Ingredient callouts

There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
  • Humectants (panthenol 0.30% - 0.75%, acetyl glucosamine 1.60% - 2.50% and glycerin 2.10% - 3.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
