spirulina for acne

Spirulina has been mentioned with a wide range of health benefits. So, what does spirulina help with? For persons with acne and other skin conditions, you might wonder, “Does spirulina for acne work?

What are the impacts of spirulina on the skin? For a long time, algae have been touted as a treatment for acne. Considering the valuable nutrients present, spirulina can be a great way to deal with acne and other skin conditions.

It contains complete proteins, vitamins, essential amino acids, iron, and omega-3 fatty acids, which aid in developing healthy skin.

In this post, I’ll dig deep and see how spirulina aids in acne treatment. Let’s get started.

Spirulina: What Does Science Say?

But first, let’s see what science says about spirulina and acne treatment.

Science doesn’t provide clear evidence to show how spirulina helps with acne. However, a study using two creams showed that spirulina affects sebum production.

Sebum is one of the root causes of acne, as it blocks skin pores. Sebaceous glands on our skin produce sebum, an oily substance that keeps the skin moist.

In the study, two groups of women were given two identical creams to apply to their faces for 28 days. While the creams were identical, one had spirulina.

After 28 days, the group of women with spirulina cream had reduced sebum production. This indicates that spirulina can reduce sebum content, leading to more open pores.

It shows that spirulina can benefit the skin in pathways that lead to acne. However, more research is needed to ascertain these claims.

Can Spirulina Be Used Both Internally and Externally?

Spirulina is edible and can be used both internally and externally. For external use, spirulina is found in several topical products. The application of these topical products on the skin helps with skin elasticity and reduces sebum production.

For internal use, spirulina can be consumed as a supplement in powder or tablet form. Growing spirulina is becoming common in homes as people look to gain from its nutritional value. There are many of Spirulina’s benefits for the skin, making this supplement a superfood.

How Does Spirulina Aid in Acne Treatment?

Spirulina helps aid in acne treatment in different ways. Mostly it works in the same way as chlorella acne removing toxins from the body, reducing sebum production, hydration, and much more.

Below are the different ways through which spirulina aids in acne treatment.

Sebum Production Is Affected

First, spirulina has been shown to affect the production of sebum. This is important as the sebaceous glands that produce sebum are a great cause of acne.

Sebum, the oily substance, keeps the skin moist but can also block skin pores leading to acne. By reducing the amount of acne produced, spirulina, in a way, aids in acne treatment.

It’s more like treating the root cause of acne.

Skin Inflammation Is Reduced

Inflammation is another great cause of sebum. In a way, inflammation is directly related to sebum production that blocks the pores. Inflammation is the second pathway through which acne happens.

When the pores are blocked, bacteria build-up starts behind the pores leading to inflammation. With bacteria build-up, the acne swells and becomes red.

With spirulina helping with inflammation, it can help reduce the effects of acne.

Provides Exceptional Protein Levels

High protein levels also contribute to the skin’s overall health. Up to 50% to 70% of the spirulina dry weight is protein. This is a pretty high content that makes part of the muscle building blocks.

The protein also helps produce collagen, which helps form part of the skin cells. While building healthy skin doesn’t directly treat acne, it can enhance your skin health. It doesn’t do any harm to improve your skin health by taking spirulina.

Hydrates Skin

The nutrients in spirulina also play a key role in hydrating the skin. The hydration can be attributed to the 11% fatty acids present in spirulina.

 The fatty acids present contain gamma-linolenic acid, better known as GLA.

GLA is widely studied and has been shown to improve skin health and hydration. With improved hydration, the skin becomes more elastic, and this has a positive effect on acne.

Promotes Cell Division

A key component in cell replication in our skin is the B12 vitamins. High amounts of vitamin B12 helps with healthy skin and hair. 

Spirulina is a good source of vitamin B12, showing how it impacts skin replication. The replication sees old cells replaced by new skin cells.

If you have acne, taking more vitamin B12 helps your skin regenerate faster. Consequently, this means the acne healing process is faster.

Provides Effective Antioxidant Property

The high amounts of antioxidants in spirulina also play a key role in fighting acne. Antioxidants protect the skin from free radical damage. This keeps the skin healthy and young-looking.

Additionally, antioxidants fight inflammation which also helps fight acne.

Improves Skin Elasticity

Lastly, spirulina can improve skin elasticity, further leaving your skin healthy. While elasticity has little to do with acne, you can do better with softer skin.

Spirulina mask benefits are numerous and can greatly enhance your skin health. You can combine the consumption of spirulina supplements with external masking for optimal results.

Is Spirulina Better for Some Skin Types Than Others?

Spirulina benefits all skin types, making it outstanding compared to other products. You can use it internally and externally without any issues.

Furthermore, it works perfectly with other skin products to help treat acne, eczema, and damaged skin barriers.

Can Spirulina Cause Acne?

Spirulina with high iodine content can trigger acne, which is never good. When buying spirulina supplements, check the iodine content and buy from reliable brands.
