Red Algae Benefits for Improving Skin Firmness

Skin sagging, wrinkles, and fine lines are perhaps the most prominent signs of aging. After all, people notice your facial complexion first. No one will likely see the flab around your midriff or grays under colored hair as much as these symptoms. Undoubtedly, this problem deserves your attention before it aggravates beyond resolution.

Research shows that sagging is the result of age-related internal influences that lead to changes within the basal cell layer. Conversely, extrinsically sun-exposed skin may also lose its elasticity in the long run. This proves that sagging and wrinkles can occur at any age rather than in your forties. 1 

Now that you understand the risk of skin aging, you should also strategize to slow down the effects of age or avoid them altogether. Fortunately, several natural remedies can help retain the firmness and radiance of your complexion over the years. In this article, we will study the benefits of red algae for the skin and highlight how it prevents the signs of aging sooner rather than later. 

Before elucidating the red algae benefits for skin, we will explain its nutritional value, mechanism, and effects. 

What is Red Algae?

When you think of algae, you picture the slimy, green seaweed growing on the ocean floor. However, it is a miracle of nature, not just because of its vibrant color but because of its right nutrient content and healing properties.  

Red algae (Rhodophyta) are a variant of algae with a distinctive deep burgundy-red hue. The color comes from phycobiliproteins, the pigment acting as the light-harvesting structures facilitating photosynthesis. As the pigment absorbs blue light and reflects red light, it enables red algae to photosynthesize and survive at great depths.

With their high vitamin and protein content, red algae are revered as a nutritious food source in Asia. In fact, it has been cultivated for food in Japan for more than 300 years. Additionally, some rhodophytes play a significant role in the formation of tropical reefs. These are coralline algae as their cell walls have calcium deposits, making them strong and durable. 2, 3

Nutritional Profile of Red Algae

Sea vegetables are often nutrient storehouses as they are loaded with B-group vitamins (B1, B2 (riboflavin), and B6), beta-carotene, and vitamin E. Red algae is no exception, and it has a high-value nutrient content, including:

  • Research shows that red algae variants are high in carbohydrates, proteins, fats, dietary fibers, and essential amino acids. 
  • They also contain omega-3 fatty acids and vitamins A, B, C, and E. 
  • Another study shows that the average protein content in red algae is far higher than the brown and green variants.
  • They contain high-quality fats such as arachidonic acid, oleic acid, EPA, and DHA.
  • Red algae also feature a very low omega-6/omega-3 ratio.
  • Sodium and iodine are present in high quantities.
  • The polyphenol content is also high. 4

The best part is that they are low on calories, despite being nutrient-dense. The impressive nutrient profile of red algae validates its benefits for skin and overall health. We will first explain the benefits of red algae for skin. 

What Does Red Algae Do For Skin?

A powerhouse of nutrients, red algae offers multiple health benefits, including those for your skin. Not to mention, it is natural, making it safe, effective, and pocket-friendly. Here are a few good reasons to include it in your daily complexion care regimen. 

Facilitates Hydration and Firmness

The primary benefit of red algae for skin is that it promotes hydration and suppleness. With its pulpy texture, red algae can store plenty of water. The quality enables it to help draw moisture to the skin surface when used as a skincare ingredient. This plumping action helps reduce the appearance of aging signs such as wrinkles and fine lines. The enhanced moisture can also prevent dryness.

Offers Antioxidant Defense

Red algae have antioxidant, antibacterial, and antifungal properties. As a potent antioxidant agent, they can defend your skin from free radicals that accelerate the aging process through oxidative damage. Cell damage is attributed to oxidative stress, which is one of the causes of aging. Being high in nonenzymatic components, algae offer a natural antioxidant defense to your skin. Bioactives like carrageenan also protect skin from environmental stressors besides the internal oxidative stress. 5

Brightens the Skin

Over the years, your skin loses more than its firmness and suppleness. It may also miss out on the youthful radiance and glow. Red algae contain vitamin C, an essential ingredient to revitalize and restore the brightness of the skin. Vitamin C also inhibits tyrosinase, which causes darkening of certain areas. Regular use of this ingredient can fade away dark spots and hyperpigmentation from acne scars and sun damage. 6

Gives Sun Protection

You can rely on red algae to provide effective protection against sun damage, one of the leading causes of visible aging. Being rich in mycosporine-like amino acids, red algae can absorb solar energy and safeguard your skin from the harmful UV rays of the sun. Studies validate that its extracts can prevent UV-induced DNA damage. The next time you reach for a sunscreen gel or lotion, check the ingredients to ensure it has red algae.  7

Promotes Acne Relief

Beta carotene in red algae makes it effective against acne. The body converts beta-carotene into retinol, an effective antimicrobial remedy. Other bioactive compounds that make red algae ideal for acne relief include polysaccharides, alkaloids, terpenoids, lipids, sterols, and phenolic compounds. Using red algae as a part of your skincare routine can give you the clear and beautiful complexion of your dreams. 8

Reduces Inflammation

Next on the list of red algae benefits for skin is its anti-inflammatory action. Skin redness caused by inflammation may happen due to allergic reactions or bacterial reactions. Although the condition doesn’t sound severe, it may lead to itchiness, dryness, and discomfort. The bigger concern about inflammation is that it indicates that the body is out of balance. With its anti-inflammatory properties, it restores the balance and relieves skin inflammation. 

Anti-Cancer Activity

Another wonderful benefit of red algae for skin is its ability to fight cancer. A recent study found that red algae contain metabolites with anti-cancer effects. Fucoxanthin, a carotenoid occurring naturally in it, shows evidence of anti-melanogenic activities. It can reduce the size of cells affected by UVB rays, lowering the risk of skin cancer. 9

Shields from Pollution

Environmental pollution can harm your skin in many ways, from causing breakouts to depriving it of its natural moisture. Red algae, with its antioxidants, can repair the natural barrier of your skin and strengthen its defenses against pollutants. Your complexion looks firm, clear, and healthy despite the prolonged exposure to the environment. 

Benefits Beyond Healthy Skin

The benefits of red algae for the skin are only the tip of the iceberg because it offers an array of additional health benefits. We will explain how red algae can help build your defenses against several diseases.

Lowers Cholesterol

Red algae contain a non-protein amino acid that lowers cholesterol in the bloodstream. An animal study found that replacing a high-cholesterol/high-fat diet with 5% seaweed significantly lowered LDL cholesterol, total cholesterol, and triglyceride levels. Fucosterol, an active compound in red and brown algae may help treat high cholesterol, diabetes, and hypertension. 10

Boosts Immunity

Marine algae polysaccharides (MAP) composed of galactose, sulfate, and uronic acids have positive effects on the immune function by triggering activation of the immune response. MAPs may even block viral adhesion to cells and attack cancer cells to protect the body from disease. Research validated the ability of MAPs to inhibit the replication of HIV and herpes. 11

Promotes Gut Health

The unique proteins and peptides found in red algae promote gut health with prebiotic effects. It improves digestion and prevents inflammation. With 47% of dry weight protein, red algae are far more beneficial than the green and brown variants. It is also high in dietary fiber. Together, these nutrients enhance microbial activity that boosts gut health and curbs exposure to carcinogens. 12

Supports Thyroid Function

Being high in iodine, seaweed helps cover the dietary recommendation of 150 micrograms per day in adults. The body falls short of making iodine naturally, leading to a deficiency in thyroid hormones. Red algae can help you address the gaps and maintain the health of your thyroid glands. Optimal levels of thyroid hormones keep the body functioning effectively and prevent weight gain, fatigue, and muscle weakness.

How is Red Algae Used for Skincare?

The benefits of red algae for skin and overall health are evident. You may find it in supplement forms, but we will mainly consider its use as a skincare product. Fortunately, you can find a broad range of products containing this potent ingredient. Topical products include masks, infused creams and serums, and spot treatment remedies. 

Since red algae shields the skin against blue light, it can enhance the potency of sunscreens to prevent photoaging. Its moisturizing properties make it an ideal ingredient for moisturizers. All you need to do is check quality products from a trusted brand and integrate them into your skincare regimen. 

Potential Side Effects and Precautions

As a first-timer exploring red algae skin benefits, you may have a fair share of doubts regarding its safety. The good thing is that it is natural, making it safe for all skin types. You may even use it for the most sensitive complexion as it has soothing and subtle ingredients. It can be applied to damaged, vulnerable, and exposed areas of your face, neck, and hands. However, you must take some precautions to be on the safe side.

Check the labels of the skincare products with red algae as an ingredient. Avoid anything containing chemicals or unknown ingredients because they may have side effects. Another precaution is to start slow with a minimal dose, even for topical application. A pea-sized dose is a good start, and you can increase it once you are sure that there are no adverse reactions. You can also do a patch test on a small area of the skin to see how it works for you. Also, ensure that the product is not close to the expiry date.
