Ingredient Spotlight: Seaweed

As seaweed is the key ingredient in our upcoming collection, it is only right that we give you access to more information as to why it is an important factor in many of your everyday products. Read this blog to learn about the benefits of seaweed for skin repair.

The abundance of vitamins and minerals found in seaweed make the benefits of having this ingredient in skincare products infinite. This blog post will outline the different types of seaweed used in our products and the benefits of each vitamin and mineral to the skin.

Seaweed in our products

You may be familiar with the scientific classification of this type of seaweed, having seen Fucus vesiculousus on your products. Commonly known as Bladderwrack, a brown seaweed found in the North Sea, Baltic Sea, Atlantic Ocean, and the Pacific Ocean. It has carotene, selenium, zinc, and vitamins A, C, and E giving it anti-ageing and anti-inflammatory benefits. The Spotless Green Sleeping Mask is infused with bladderwrack to provide soothing hydration from natural fatty acids that prevent the development of cystic acne caused by the excessive build-up of sebum, bacteria, and dead skin over time.

Organic kelp and kelp powder also known as Ascophyllum nodosum grow in cold water oceans. These large brown algae are a major source of iodine, calcium, iron, copper, potassium, magnesium, vitamins A, B1, B2, C, D, and E. Among its many benefits, kelp powder helps to hydrate the body and restore the natural balance of PH levels. In our Sea You Serum, we've combined both kelp powder and bladderwrack for extra hydration for those with dry and flaky skin. Serums are a great addition to any skincare routine as they help to seal in moisture, the added benefit of kelp powder means that moisture is retained for much longer. 

Mineral and vitamin breakdown

Carotene (beta carotene) is converted into vitamin A which promotes healthy skin by encouraging the development of healthy skin tissue which in effect contributes to the skin's ability to heal scarring and fight against acne.

Selenium is an antioxidant that neutralises free radicals, similar to vitamin E in that it safeguards cell membranes and inhibits the breakdown of collagen caused by UV damage.

Zinc deemed a 'trace mineral' (because you need a very small amount) is found in every single cell in the human body and therefore can be attributed to many benefits. One is its role in boosting immune function and reducing the excessive oil production that leads to cystic acne. Zinc pyrithione can also be used to treat eczema and psoriasis as its anti-inflammatory properties calm irritation and relieve itchiness.

Iodine encourages detoxification and regulates the moisture levels in the skin and triggers cell reproduction in the lower layers of the skin.

Calcium is stored in the epidermis, the outermost layer of the skin, and regulates sebum production to keep skin hydrated.

Iron activates B vitamins which in turn give your skin a natural glow.

Copper peptides in cosmetics, help the skin regenerate collagen and elastin which improves skin firmness and elasticity in addition to increasing blood circulation. However, the benefits of copper-peptides only show over a long period of use, usually, after one to three months of consistency as copper can only be incorporated in trace amounts.

Potassium is known to be extremely hydrating and key in controlled moisture retention when ingested, and although potassium can't be absorbed through the skin when it's applied to the skin it behaves similarly to ingested potassium by enhancing moisture and reducing texture.

Magnesium is mostly known for its benefits to bone development and fatigue, however, magnesium also improves your skin's overall appearance, reducing acne and other skin disorders by lowering cortisol levels. The topical application of magnesium through creams and serums is proven to be a fast way of replenishing the mineral to your body. 

 

Vitamin B1 thiamine boosts the immune system and also soothes the nervous system. B1 is attributed to helping prevent stress-related breakouts while Vitamin B2 riboflavin contributes to keeping the skin moisturised.

Vitamin C minimises the appearance of fine lines by activating cells called fibroblasts that produce collagen which keeps your skin firm by boosting elasticity. And since vitamin C is stored in the skin, it helps rejuvenate and protect your complexion whether you get it from food or apply it topically.

Vitamin D is famously associated with sun exposure, even complexion, and glowing skin. In part, these assumptions are correct exposure to the sun catalyses the skin's production of vitamin D, which has antimicrobial properties that are key in minimising acne caused by bacteria. However, it hasn't been proven that vitamin D plays a role in clearing scarring or hyper-pigmentation.

Vitamin E is most concentrated in the sebum produced by our oil glands and if you have read our blog post on oil exfoliation an equally high saturation of Vitamin E in Jojoba Oil is the reason it is considered the best oil for moisturisation. As well as neutralising free radicals this vitamin also absorbs UVB rays –– the spectrum of sunlight responsible for burning skin and ageing.

It is very rare for a single ingredient to encompass so many benefits and that is what makes seaweed such a unique and necessary ingredient in skincare. Having read over ten different properties, it should now be evident as to why seaweed is ideal for skin health, you should also keep an eye out for these ingredients moving forward and purchase more products with these key vitamins when suffering from chronic skin conditions.

And finally, as the health benefits of seaweed to your skin for acne, eczema, psoriasis, and other skin conditions are most significant in the healing process there is no excuse not to incorporate seaweed infused products into your skincare routine.
