When you think about the ocean, you probably think about holidays, sunshine and that effortlessly glowy skin you always seem to come home with (well I like to think I do!) But have you ever wondered why a few days by the sea does actually leave your complexion looking so much better? It's not just the relaxation (although that of course helps!)
The ocean is one of nature's most extraordinary sources of skin-loving ingredients (think seaweed, algae, marine collagen, sea water minerals and deep-sea extracts) all of which have a remarkable ability to transform the look and feel of your skin (we’re talking next-level hydration, boosted radiance, improved firmness and a calmer, stronger skin barrier.) And while the skincare world has long recognised the power of marine ingredients, right now they are having a well-deserved moment, and once you understand what they can do for your skin, you'll wonder how your skincare routine ever existed without them!
Keep reading to discover why marine ingredients are so good for your skin and the sea-inspired skincare we know you’ll love!
The marine ingredients to look for in your skincare
Honestly, we aren’t joking when we say the sea is a treasure trove of high-performance actives! Here are the key ones to know (and look for in your skincare) when it comes to delivering visible results;
Seaweed (the hydration hero)
Seaweed is one of the most powerful marine ingredients in skincare. Naturally rich in vitamins (A, B, C, D & E), minerals (such as magnesium, manganese, calcium, copper, iodine, iron, potassium, phosphorus & zinc), proteins, essential fatty acids and amino acids, seaweed helps to deeply hydrate, strengthen the skin barrier and improve overall skin health. Seaweed is also known for its ability to boost radiance and leave the skin looking fresh, plump and revitalised. Oh, and it’s packed with antioxidants to fight off environmental damage and pollution too! Topically applying seaweed has next to endless, positive results!
Marine Collagen (for firmness and elasticity)
Marine collagen is a go-to ingredient for ageing skin. Unlike some traditional sources, marine collagen is known for its superior bioavailability.
It helps support the skin’s structure, improving firmness and elasticity and "plumps" the skin from the inside out, reducing the appearance of fine lines. It’s particularly beneficial if your skin is starting to feel thinner, less resilient or lacking bounce.
Sea Water & Marine Minerals (for balance and skin health)
Sea water is far more complex than its name suggests. It contains 104 trace elements essential to the vitality and health of human skin (many of which we are chronically deficient in thanks to modern diets and lifestyle!) It’s naturally rich in essential minerals like magnesium, calcium and potassium, which help to rebalance and remineralise the skin. These minerals support hydration, improve skin function and help maintain a healthy, glowing complexion.
Here's something interesting! Our bodies are naturally deficient in negative ions. The sea air and ocean water are naturally rich in these negative ions which is one of the main reasons we feel so energised, revitalised and clear-headed after spending time by the sea. Today, professional marine skincare is able to capture and deliver these same benefits topically. Amazing right?
Sea Salt (for detoxification)
Sea salt a powerful exfoliant with healing and deeply detoxifying properties. It absorbs dirt, impurities and toxins from the skin while delivering a mineral hit that improves circulation, boosts lymphatic drainage and helps reduce inflammation. The mineral content ( particularly magnesium, calcium and potassium) helps restore the skin's protective barrier function and keeps it hydrated and resilient.
Marine Magnesium (for calming, balance and skin resilience)
Found naturally in sea water, marine magnesium is one of the most essential minerals for skin health, and 90% of us are deficient in it! It’s best known for relaxing tired muscles but when applied topically, offers a multitude of powerful therapeutic benefits! It helps combat dryness, fluid retention and the ageing process, and has been shown to improve overall skin texture and tone. Importantly, research shows that topical application of magnesium is more efficiently absorbed than taking a supplement as it penetrates directly through the skin and into the bloodstream, taking immediate effect!
Marine magnesium also plays a role in maintaining healthy hydration levels, helping the skin feel more comfortable, resilient and visibly balanced.
Algae Extracts (for protection and repair)
Different types of algae (like red, green and brown algae) are packed with proteins (amino acids make up to 60% of most of these plants), phosphorus, magnesium, copper, calcium and both vitamin A & B1. While algae is not as potent as seaweed they still have a multitude of benefits from soothing, regenerating and barrier repair (they also protect skin from environmental stress and premature ageing), explaining its frequent use in anti-ageing products!
Marine Bio-Actives (for overall skin performance)
These are advanced ocean-derived ingredients designed to support multiple skin functions at once, from hydration and repair to firming and radiance. They work in harmony with the skin, making them incredibly effective yet gentle.
