What the product description says
“Key Ingredients & Benefits Niacinamide , Can reduce the appearance of pores, brighten skin tone and hydrate.”
Source: Oh K!

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

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, panthenol

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.

Source: Oh K!

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

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.

What the product description says
“Our biodegradable sheet mask is infused with this powerhouse ingredient to help improve texture and tone, minimise the appearance of pores and fine lines and support skin barrier function.”
Source: Oh K!

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: centella asiatica extract.

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.

This product contains antioxidants (centella asiatica extract) 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.

Product summary

Ingredient callouts

  • A good concentration of Niacinamide (4.50% - 5.50%). 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.
  • An effective concentration of Panthenol (pro-vitamin B5) - about 2.40% - 2.90%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
  • Humectants (sodium hyaluronate crosspolymer 0.25% - 0.45%, sodium hyaluronate 0.35% - 0.60%, pantolactone 0.30% - 0.55%, panthenol 2.40% - 2.90%, hydrolyzed glycosaminoglycans 0.25% - 0.45%, hyaluronic acid 0.15% - 0.30%, glycerin 3.10% - 3.80% and hydrolyzed hyaluronic acid 0.20% - 0.35%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
