The Benefits of Amino Acids for Your Skin

Amino Acids Benefits for Your Skin


Amino acids are integral for a number of vital processes in your body, and especially in your skin. Without getting too bogged down in all the heavy scientific details, amino acids are compounds that act as building blocks to produce various proteins in your skin. 


Without amino acids, your skin would be unable to synthesize important structural proteins, including collagen and elastin. Without those, your skin would quickly become thin, dry, and rough. Did we also mention that your skin wouldn’t be able to heal itself properly?


So, as you have probably guessed by now, amino acids are incredibly important when it comes to maintaining healthy skin.


While some amino acids are naturally produced by your body, they can also be used as a topical treatment. When added to skincare products, they improve hydration while making your skin more resilient to harmful environmental stressors. They also provide anti-aging benefits by boosting the natural production of collagen and elastin. In this blog, we’ll be discussing the top five benefits of using amino acids on your skin.

Types of amino acids, best amino acids for skin

Our body is able to produce its own amino acids; these are known as non-essential amino acids. Non-essential doesn’t mean that they’re not important, it simply means we don’t need to find them from foods and supplements. Essential amino acids, on the other hand, are those that we need to source from various plant and animal-based products.


Essential amino acids can be found in various skincare products. Many companies use animal-based amino acids, but you can find plant-based ones, too. 


The fermentation of rice produces beneficial amino acids for your skin, which is why sake kasu and rice ferment are the key ingredients in our Sake Kasu Overnight Replenishing Mask. We’ve also added a combination of other useful plant-based amino acids, including lysine, arginine, and glutamine. Not only are these beneficial for your skin, but they also help to boost the benefits of the mask’s main ingredients.


There are various types of amino acids, and each one has a different job to do for your skin. The most common amino acids to look out for in beauty products are:


  • Lysine – Firms your skin, providing anti-aging benefits.
  • Histidine – Provides antioxidant benefits.
  • Glycine – Improves the skin’s elasticity.
  • Arginine – Helps to repair your skin.
  • Leucine – Helps to reduce the appearance of fine lines and wrinkles.
  • Glutamine – Repairs the skin’s barrier function and provides moisture.
  • Glycylglycine – Helps to normalise pore size

Who can use amino acids?

Amino acids are a natural, organic compound and therefore present little to no side effects. They can be used safely by all skin types, even on those with sensitive skin including eczema and psoriasis. 

What are the main benefits of amino acids?

Amino acids aren’t just a one-trick pony – they provide a huge number of benefits to your skin. From boosting hydration to plumping and protecting, you’ll want to add them to your routine once you’ve read these top five benefits.

They nourish your skin and boost hydration

Natural moisturizing factors (NMFs) are substances in the upper layers of your skin that work to keep it smooth and hydrated. NMFs are made up of amino acids, ceramides, and fatty acids that are naturally produced by your body. However, applying an amino acid infused cream directly onto your skin will provide the same nourishing benefits. 

They act as antioxidants

Amino acids also act as antioxidants for your skin, protecting it against environmental stressors, such as pollution, and the sun’s damaging UV rays. They have also been found to stimulate the production of an antioxidant known as glutathione, therefore supporting your skin’s natural defenses.


According to research, histidine is a particularly effective antioxidant, and may also provide anti-inflammatory effects to soothe your skin.

They help to repair your skin’s natural barrier

Your skin has a natural barrier that acts as a protective shield, preventing moisture from getting out, and potential irritants from getting in. It’s often compromised in those with dry skin, or in conditions including eczema and psoriasis. Amino acids help to repair and support your skin’s protective barrier.

They stimulate collagen production – amino acids for skin tightening

Collagen is a protein responsible for your skin’s firmness and elasticity. As we age, our skin produces less collagen, leading to sagging and wrinkling. Amino acids have been found to boost your skin’s natural production of collagen and elastin. Over time, this leads to a plumper and more youthful appearance.


A study into the use of amino acid creams for anti-aging purposes found that after four months of daily use, the appearance of fine lines and wrinkles significantly improved.

They help to heal your skin

Amino acids have also been found to accelerate the skin’s healing process, which is useful if you suffer from breakouts, or experience sore, cracked skin. They also boost your skin’s cell turnover rate, which over time can help to reduce scars and stretch marks.


Why the Future of Beauty is Vegan



Fun fact: Hakko Skincare keeps both animals and your skin safe and happy.

Not-so-fun fact: There are still so many brands out there who are harming animals, and consequently harming your skin.

Accessible skincare has been booming since the 1900s, with thousands of brands paving the way to make beautiful skin available to everyone. A century later, after many trials and tribulations, people have started to realise that an amazing skincare routine is not worth the sacrifice when it comes to testing on animals or using animal-derived ingredients.

We don’t need to lecture you on why you shouldn’t support brands that take part in animal cruelty (that’s a no brainer – cruelty means cruelty) – so instead, we’re going to shower you with reasons why you are a superstar by going vegan with your skincare.

Vegan products earn a big high-five from your skin because a lot of animal-derived ingredients can wreak havoc on that precious epidermis of yours, by being highly processed with toxic additives like antibiotics, odour removers and unsafe hormones (yep, that’s your cue to run).

Consequently, non-vegan products are more than what meets the eye. No company would proudly disclose that their products contain parts of pigs or extracts from fish. Instead, these animal-based ingredients can hide under names like carotene, collagen, lipids, balms and hyaluronic acid. And although all of the above do garner benefits, vegan alternatives are clinically proven to work just as hard (if not harder), but with zero harm to animals or the environment. There is an endless list of vegan ingredients, that function as dermatological dreams, eliminating the need for animal-based products entirely.

Vegan-friendly skincare is also eco-friendly skincare, another thing that non-vegan products can’t claim. If we could give the planet a big hug in light of recent environmental disasters, we would. But due to our physical incapability, creating what we like to call eco-fabulous products is the next best thing. By leaving animals out of the question, you as an amazing human, also promote sustainability by boycotting the demolition of land, unnecessary use of water and release of gross emissions that would otherwise go towards farming those poor creatures.

Cruelty-free products have universal benefits, no matter what age, skin type or sized bank account you have. There are no limits to what the power of vegan products can do. Dry skin? Been there. Anti-ageing? Done that. From face masks, to serums, to lotions and eye creams, the future of beauty is vegan because a lot of awesome brands (including ours) have jumped aboard to save your skin, save the animals and save the planet – all while doing the best for your skin, unparalleled in efficiency and results. By avoiding animal testing and animal-derived ingredients, skincare brands like ours get to pack even more miracle-workers into our products so that you can reap the benefits. Your skin absorbs everything you choose to spoil it with, and vegan products are the best thing you could possibly feed it. Talk about bang for your buck!

So, be conscious and be great, and your skin will thank you later.
