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.

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~2.2–2.6%

Centella asiatica leaf extractEffect: LowA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. It can be irritating to sensitive skin. Might be helpful in preventing stretch marks. It could, however, itself be irritating.~0.8–1.15%

Rosmarinus officinalis leaf extractUnder-dosedCan be helpful in reducing inflammation in skin, including inflamed acne. It can be irritating~0.6–0.9%

Anti-aging

What the product description says

“This lightweight texture is packed with active ingredients like Vitamin C & E, Amino Acids, and Niacinamide, that will leave your skin plumped & brightened all while boosting your skin's elasticity.”

Source: N/A

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 leaf extract, lysine, serine, threonine.

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.

Tetrahexyldecyl ascorbateUnder-dosedBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~2.4–3%

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: alanine, 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.

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: alanine, arginine.

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: arginine, butyrospermum parkii butter.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ap, ceramide as, ceramide eop, ceramide np, ceramide ns, niacinamide, panthenol

Product summary

Ingredient callouts

A good concentration of Niacinamide (2.20% - 2.60%). 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.
Ceramides (ceramide eop 0.30% - 0.55%, ceramide as 0.30% - 0.55%, ceramide ap 0.35% - 0.65%, ceramide ns 0.50% - 0.70% and ceramide np 0.70% - 1.05%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
An effective concentration of Panthenol (pro-vitamin B5) - about 1.70% - 2.10%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
Humectants (arginine 0.50% - 0.75%, glutamic acid 0.65% - 0.95%, glycine 0.60% - 0.90%, alanine 0.65% - 0.95%, pca 0.65% - 0.95%, sodium lactate 0.65% - 0.95%, sodium hyaluronate 0.65% - 0.95%, betaine 0.65% - 0.95%, sodium pca 0.95% - 1.15%, panthenol 1.70% - 2.10% and glycerin 3.10% - 3.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
