What the product description says
“Improves overall redness, sensitivity and premature aging.”
Source: Lila Beauty

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

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.

NiacinamideKey activeEffect: 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~4.9–7.3%
Zinc pcaEffect: LowA 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~2–3%

What the product description says
“Strengthens skin barrier and has a gentle and lightweight formula”
Source: Lila Beauty

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

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

“Cos De BAHA Niacinamide 10% Serum helps to reduce the appearance of hyperpigmentation and dark spots.”
Source: Lila Beauty

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: 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: dipotassium glycyrrhizate.

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

"Cos De BAHA - Niacinamide 10% Serum" is effective for: Anti-aging, Moisturizing, Anti-blemish and Evens skin tone

Ingredient callouts

  • A good concentration of Niacinamide (4.90% - 7.30%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. 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.
  • Dipotassium Glycyrrhizate in this product (0.60% - 1.40%) can also further help improve the skin barrier. It might be able to calm down inflammation and reduce sensitivity. Dipotassium Glycyrrhizate is an active compound from the licorice root.
  • In addition, this product contains Allantoin (0.85% - 1.25%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
  • Humectants (sodium hyaluronate 1.20% - 1.80%, zinc pca 2.00% - 3.00% and glycerin 3.20% - 4.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price
