algin
A marine-derived hydrator that locks in moisture and soothes irritated skin.
Hydration AND
Barrier Protection
A study published in Marine Drugs discusses the application of alginates in cosmetics, highlighting their role in maintaining proper skin moisture and protecting the skin barrier.
Oil Absorption &
Detoxification
An article in Processes examines the moisture content of sodium alginate-based films, noting that the presence of glycerol acts as a water-holding agent, which may contribute to oil absorption and detoxification properties in skincare applications.
Anti-Inflammatory
AND Wound Healing
Research in Marine Drugs reviews the preparation of alginate-based biomaterials and their applications in wound healing, emphasizing alginate’s ability to absorb excess wound fluid, provide a moist environment, and promote wound healing.
Algin, also known as sodium alginate, is a polysaccharide derived from brown seaweed (Phaeophyceae). It has hydrophilic (water-attracting) properties, forming a gel-like texture when mixed with water. This allows it to create a moisture-locking barrier on the skin, preventing dehydration.
Algin is renowned for its ability to hydrate, soothe, and detoxify the skin – it has ion-exchange capabilities, meaning it can bind to heavy metals and toxins, making it a natural skin detoxifier.
How ALGIN Works in Skincare
It is highly valued for its water-binding and film-forming properties, making it a staple in various cosmetic and pharmaceutical applications. When applied to the skin, it acts as a moisture-locking agent, preventing dehydration while simultaneously soothing irritation and supporting the skin’s natural barrier function.
Key Benefits in Skincare
🌊Deep Hydration & Moisture Retention
One of algin’s standout qualities is its ability to retain moisture. As a hydrophilic compound, it attracts water molecules and forms a protective film on the skin, keeping it hydrated throughout the day. This property is especially beneficial for dry and dehydrated skin types looking for long-lasting hydration.
🍀Soothing & Anti-Inflammatory Effects
It is known for its calming and anti-inflammatory properties, making it a great addition to formulations for sensitive or irritated skin. Helps to reduce redness, relieve itching, and provide comfort to compromised skin.
🌏Detoxification & Pollution Defense
Due to its ion-exchange capabilities, it has the ability to bind to heavy metals, pollutants, and other impurities, effectively removing them from the skin. This detoxifying property makes it an excellent ingredient for anti-pollution skincare products.
🧼Oil Control & Sebum Regulation
For individuals with oily or combination skin, it can help regulate sebum production without stripping the skin of essential moisture. Its gentle oil-absorbing nature makes it a key ingredient in balancing skincare formulations.
How to Incorporate Algin into Your Skincare Routine
This ingredient is commonly found in:
- Moisturizers to reinforce the skin barrier like our Niacinamide Gel Moisturizer
- Hydrating serums to lock in moisture like or Double Boost Hydration Gel
- Soothing face masks for calming redness
- Cleansers to remove impurities and excess oil
Sodium alginate is not enough talked about hero in skincare, offering a multi-functional approach to hydration, soothing, detoxification, and oil control. Whether you’re looking to quench dry skin, calm irritation, or protect against environmental aggressors, this is a natural, science-backed ingredient worth incorporating into your routine.
