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.
