Why use seaweed in modern Cosmeceutical Skin Care Formulations?
Historically the cosmetic industry has used many synthetic ingredients in formulations which have been proven to be highly ineffective with low absorption rates and harmful side effects - some of these are really nasty.
The industry is changing - lead by more educated consumers. A distinct shift towards more natural ingredients is happening.
Independent brands like Kalōnology are matching their latest cosmeceutical formulations with the latest technology in packaging which allows them to safely get these sensitive ingredients out to the consumer in airless refill technology which is capable of protecting these ingredients for longer.
Kalōnology's entire collection is based on Marine Natural Bioactive Ingredients - including Seaweed Polysaccaride Gel:
Polysaccharides represent around 60% of all active metabolites occurring in seaweed. They are composed by several building blocks (monosaccharides) linked by glycosidic bonds, forming long chained carbohydrates. These compounds are characterised by being hydrophilic, water-soluble and to possess a regular structure.
Polysaccharides have a structural role on seaweeds cell wall and as an energetic reservoir. Seaweed contains several polysaccharides with proven biological activities, some Polysaccharide groups are detailed below:
1. Carotenoids are lipophilic isoprenoid compounds, in which astaxanthin, fucoxanthin, loraxanthin, lutein, violaxanthin, zeaxanthin, are categorised as xanthophylls, whereas α-carotene, β-carotene, lycopene are categorised as carotenes. In general, these compounds present several bioactive properties, such as anti-inflammatory and antioxidant. They have pro-vitamin A which can remain active, particularly at low oxygen rates, where normally vitamin C cannot.
2. Astaxanthin is also extracted and has a wide range of bio-activities, such as anti-oxidative, anti-inflammatory, anti-neoplastic - turning it in a very interesting ingredient.
3. Fucoxanthin is usually found on brown algae and the main responsible for the yellowish-brown or olive-green coloration of these seaweeds. It has high antioxidant activity, and its main bio-activities are anti-malarial, anti-tumour, anti-obesity, anti-inflammatory, anti-diabetic, and anti-angiogenic activities. It also has protective effects on the brain, skin, liver, blood vessels, bones, and eyes.
Many other benefits exist related to these amazing Marine plant species, we will write more on this subject in the future.
