What the product description says
“Moist Lotion”
From product name

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, algae extract.

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, chondrus crispus extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

Aspartic acidKey active· HumectantEffect: HighAn amino-acid that helps increase skin hydration and might help to slightly improve skin firmness, potentially reducing lines and wrinkles~0.3–0.7%
Chondrus crispus extractKey active· OcclusiveEffect: HighRed algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~1.8–2.8%

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~2.9–4.3%

Evens skin tone
Not advertised by the brand · 2 ingredients credited for this claim

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.

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.

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~2.9–4.3%
AlanineEffect: LowAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~1.2–1.8%
Anti-aging
Not advertised by the brand · 5 ingredients credited for this claim
Strong support

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: aspartic acid, 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.

It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

Product summary

Based on the ingredient list, "Grant SCIENCE WATER - Moist Lotion" can work well for skin moisturization. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Grant SCIENCE WATER - Moist Lotion ticks this box. Alanine, algae extract, arginine, aspartic acid and diglycerin in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Algae extract, arginine, chondrus crispus extract and pentylene glycol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • We love that this moisturizer contains a good concentration of niacinamide 2.90% - 4.30%. Niacinamide is a perfect active in a moistruizer because it helps calm down inflamation in skin and support the skin barrier. More than that, it is helpful for most common skin concerns: it helps regulat oil production, help reduce acne and clogged pores, improve skin tone and prevent pigmentation marks. It also helps fight photodamage.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: allantoin

Irritation risk

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
