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: arginine, glycerin.

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, helianthus annuus seed oil.

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. 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~2.3–2.8%

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.5–0.8%

Simmondsia chinensis seed oilKey active· Emollient, OcclusiveEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~5.4–6.5%

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3–3.6%

Potassium azeloyl diglycinateKey activeEffect: MediumA derivative of azelaic acid. It is obtained by reacting the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium azeloyl diglycinate is better soluble in water compared with azelaic acid. Because of this property, products with potassium azeloyl digclycinate can have a nicer texture~1.2–1.4%

Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.65–0.95%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.5–0.75%

ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.2–0.35%

Aloe barbadensis leaf juice· HumectantEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~1.9–2.3%

LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.25–0.45%

Avena sativa kernel extractUnder-dosedAn effective moisturizing and skin barrier repair ingredient. Helps calm down inflammation and has some anti-oxidant properties~1–1.2%

Laminaria saccharina extractUnder-dosedA seaweed extract that contains sugars and can be helpful in attracting water to the upper layers of the skin if used in high enough concentrations~0.5–0.75%

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.

Aloe barbadensis leaf juiceEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~1.9–2.3%

3-o-ethyl ascorbic acidEffect: LowA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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~1.6–2%

Laminaria saccharina extractEffect: Low, below effective doseA seaweed extract that contains sugars and can be helpful in attracting water to the upper layers of the skin if used in high enough concentrations~0.5–0.75%

Evens skin tone

Side benefit · Niacinamide, 3-o-ethyl ascorbic acid + 2 more

Works well

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

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: 3-o-ethyl ascorbic acid.

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.

3-o-ethyl ascorbic acidKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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~1.6–2%

Pisum sativum extractEffect: Low, below effective doseMight be helpful in protecting skin collagen and elastin from breaking down but solid research is lacking~0.35–0.65%

Anti-blemish

Side benefit · Niacinamide, Potassium azeloyl diglycinate + 1 more

Works well

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.

In addition, this product contains potassium azeloyl diglycinate. It can help in reducing blemishes, even though it is less effective.

Anti-oxidation

Side benefit · 3-o-ethyl ascorbic acid, Curcuma longa rhizome extract + 2 more

May help

This product contains antioxidants (3-o-ethyl ascorbic acid) 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.

Curcuma longa rhizome extractEffect: LowA plant extract that might have some anti-oxidant properties but there is no evidence of effectiveness in skin~0.55–0.8%

Terminalia ferdinandiana fruit extractEffect: LowA plant extract that might have some anti-oxidant effect in skin, but evidence is lacking~0.45–0.65%

Avena sativa kernel extractEffect: Low, below effective doseAn effective moisturizing and skin barrier repair ingredient. Helps calm down inflammation and has some anti-oxidant properties~1–1.2%

Product summary

"OSEA® Malibu - Anti-Aging Sea Serum" is effective for: Anti-aging, Moisturizing, Evens skin tone and Anti-blemish

Ingredient callouts

A good concentration of Niacinamide (2.30% - 2.80%). 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.
Panthenol (pro-vitamin B5) at about 0.50% - 0.80% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
Humectants (panthenol 0.50% - 0.80%, arginine 0.20% - 0.35%, sodium hyaluronate 0.50% - 0.75% and glycerin 3.00% - 3.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
