From the Guidelines
Topical blue-green algae offers several aesthetic benefits for skin, primarily improving skin hydration, reducing inflammation, and fighting signs of aging, as supported by its nutrient-dense composition and antioxidant properties. The benefits of topical blue-green algae for skin are numerous, including:
- Improving skin hydration
- Reducing inflammation
- Fighting signs of aging
- Calming redness and irritation due to its anti-inflammatory properties
- Nourishing the skin with amino acids, vitamins, and minerals
- Supporting collagen production, potentially reducing the appearance of fine lines and wrinkles
- Protecting skin from environmental damage and oxidative stress due to its high antioxidant content
When using blue-green algae topically, it is recommended to look for products like serums, masks, or moisturizers containing spirulina or Aphanizomenon flos-aquae (AFA) 1. For best results, apply these products to clean skin once or twice daily, following package instructions. Most people can safely use blue-green algae topically, but those with sensitive skin should perform a patch test first. The effectiveness of blue-green algae comes from its nutrient-dense composition, which provides the skin with beneficial compounds that support cellular repair and protection.
It is essential to note that while the provided evidence does not directly discuss the benefits of blue-green algae, the most recent study 1 mentions the examination of complementary and alternative therapies, including botanical or plant-derived agents, which may be relevant to the discussion of blue-green algae. However, the current evidence is insufficient to develop a specific recommendation on its use for acne treatment.
In the context of real-life clinical medicine, prioritizing morbidity, mortality, and quality of life, it is crucial to consider the potential benefits and risks of using topical blue-green algae, especially for patients with sensitive skin or underlying conditions. As the evidence is limited, it is recommended to consult with a healthcare professional before using any new skincare products, including those containing blue-green algae.
From the Research
Aesthetic Benefits of Topical Blue Green Algae for Skin
- The applications of microalgae in cosmetic products have recently received more attention in the treatment of skin problems, such as aging, tanning and pigment disorders 2.
- Spirulina, a type of blue-green algae, has been shown to have a good influence on the proliferation of dermal fibroblasts and keratinocytes, extracellular matrix, and collagen production, as well as exerting antioxidant and anti-inflammatory action 3.
- The use of Spirulina in cosmetics may promote a healthy environment for skin's cells and structure, cooperating for anti-aging, photoprotection, and wound-healing effects 3.
- Some compounds of Spirulina also exert a lighting property through tyrosinase inhibition, which can be beneficial for skin whitening and pigmentation reduction 3.
- Additionally, Spirulina's antimicrobial action can be advantageous to skin, contributing to anti-acne, antibiofilm, and anti-herpes effects 3.
- Overall, Spirulina presents multi-benefits and shows an improvement in the general aspect of skin, making it a potential ingredient for cosmetic products 3.
