“By The Sea Mineral Lotion harnesses the power of Japan’s Izu-Akazawa deep sea water and marine plant-derived ingredients to provide hydration for clearer, more balanced and brighter-looking skin.”
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:
algae extract, 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: algae extract, pentylene glycol.

Ingredients
Filter by role to see what each ingredient is doing.
Sea water~26–39%
- Irritation risk
- Low
Dissolves other ingredients. It does not have additional skin benefits compared to plain water
More about Sea waterGlycerin~5.4–8.1%
- Irritation risk
- Low
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
More about GlycerinGlycereth-26~4.4–6.6%
Alcohol~3.1–4.6%
- Irritation risk
- High
Can be drying and contribute to skin irritation. Used in formulars to dissolve other ingredients, create a thinner product consistency or for its antibacterial properties
More about AlcoholWater~2.2–3.3%
Dipropylene glycol~1.7–2.6%
- Irritation risk
- Low
Helps to dissolve other ingredients in a formulation. Slows down the rate of product drying
More about Dipropylene glycolPentylene glycol~1.6–2.4%
- Irritation risk
- Medium
Used to preserve products, dissolve other ingredients and create a nice product texture
More about Pentylene glycolMethyl gluceth-10~1.2–1.8%
Saccharide isomerate~0.95–1.4%
- Irritation risk
- Low
Helps attract water to the upper layer of the skin
More about Saccharide isomerateButylene glycol~0.55–1.3%
- Irritation risk
- Low
Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin
More about Butylene glycolPhenoxyethanol~0.4–0.95%
- Irritation risk
- Low
A preservative. It helps prevent bacterial growth in cosmetic products
More about PhenoxyethanolSodium lactate~0.35–0.85%
- Irritation risk
- Medium
Helps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product
More about Sodium lactatePolyglyceryl-10 oleate~0.3–0.7%
- Irritation risk
- Low
Helps soften the upper layer of the skin
More about Polyglyceryl-10 oleateEthylhexylglycerin~0.15–0.6%
Lactic acid~0.15–0.55%
- Irritation risk
- Medium
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
More about Lactic acidAlgae extract~0.15–0.65%
- Irritation risk
- Low
- Comedogenicity
- 3/5
Plant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet
More about Algae extractHydroxypropyl methylcellulose~0.15–0.6%
- Irritation risk
- Medium
Used to create a thicker product consistency and stabilize the formulation
More about Hydroxypropyl methylcelluloseZostera marina extract~0.1–0.3%
- Irritation risk
- Low
Sodium hyaluronate~0.05–0.2%
- Irritation risk
- Low
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
More about Sodium hyaluronateLactobacillus ferment~0.05–0.2%
- Irritation risk
- Low
A fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative
More about Lactobacillus fermentRosa rugosa flower extract~0.05–0.15%
- Irritation risk
- High
