Amino Acids in Skincare

The Building Blocks of Skin



  • Nourish your skin and boost hydration
  • Help production of antioxidants
  • Strengthen the immune system
  • Maintain the skin’s hydration, resilience and an overall healthy appearance
  • Protect skin from free-radical damage including UV
  • Help repair skin’s natural barrier – reduce the signs of aging

What are Amino Acids?

Amino Acid Skincare – Amino acids are the building blocks of both peptides and proteins. They maintain the skin’s hydration, texture, resilience, and an overall supple, healthy appearance. There are many amino acids, but most scientists agree that there are twenty (20) that are important to our health, divided into two types: essential and non-essential.

  • The “non-essential” term doesn’t mean that those amino acids aren’t important; rather, it means that your body can make them on its own, so it’s not “essential” for you to get them elsewhere, such as from food or supplements.
  • “Essential” amino acids, on the other hand, are essential because they must be obtained from foods or supplements; a deficiency in even one of them can result in health problems.

Amino acids are naturally present in skin, as part of what’s called our natural moisturising factors (NMFs). Within skin’s uppermost layers, they work as conductors, orchestrating an incredibly complex “concert” that allows our skin to thrive and to stay hydrated. When added to skin care products, they improve hydration while making your skin more resilient to harmful environmental stressors.

Without amino acids, our skin would not be unable to synthesize or boost important structural proteins, including collagen and elastin. And without these, our skin would quickly become thin, dry, and rough and would not be able to heal itself properly.

There are 9 essential acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. They are found mainly in products that contain animal proteins (such as seafood, beef, poultry, dairy products and eggs) but also in vegetables such as quinoa and soy products.

The 11 non-essential acids are: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine and tyrosine. Some of these non-essential amino acids are only produced when we are sick or stressed.

What are the Best Amino Acids for Skin Care?

All essential and non-essential amino acids play a role in getting beautiful skin, however, there are some that have extra benefits;-

  • 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.

Who can use Amino Acids?

Amino acids are a natural, organic compound and therefore present little to no side effects. They act as water-binding agents, and some have antioxidant properties. They work best when they are combined with other ingredients that have skin-restorative ability to work in unison to fight signs of aging. They can be used safely by all skin types, even on those with sensitive skin.

They have a distinct ability to bind to water molecules, allowing them to greatly increase hydration in the skin. They can also help protect the skin’s moisture barrier by helping to balance pH levels. When the skin’s acid/base levels are off, your skin can’t effectively prevent dangerous substances, including bad bacteria, from entering the skin, which can result in acne breakouts and other undesirable blemishes, even skin infections.

If your skin is dehydrated, it will often produce more oil to compensate, resulting in an oily, congested complexion. If your skin is properly hydrated – the less visible lines and wrinkles will be, leaving your skin supple and firm.

A Guide to Selecting the Best Skincare Products

Your skin is the bodies largest organ. Its major functions are protection, regulation and sensation. If our skin is not functioning to its full ability, these functions may become compromised.

It’s easy to get lost in the sea of skincare options these days. Not only are there doctors, dermatologists, skin professionals and aestheticians telling you this or that, you also have YouTubers, bloggers and beauty enthusiasts flooding you with thoughts and ideas too. It’s no wonder there are so many skin issues and concerns these days. When you don’t know where to start or what information is reliable, how is your skin really going to respond? More importantly, the use of incorrect skincare products can actually exasperate your condition or cause additional skin problems.

The use of professional active ingredient skincare is recommended. The “Professional” skincare products we recommend on this site can only be purchased through certified stockists and practitioners who are required to provide their professional advice on the application of these products, (as opposed to those you can purchase over the counter (OTC) in the department stores and supermarkets). These recommended professional products contain;-

  • higher levels of active ingredients to boost your skin’s health and correct skin problems
    (OTC product lines have less active ingredients to minimise the chance of irritation to protect the buyer)
  • are backed by clinical studies
    (not exaggerated unsubstantiated claims)
  • are made in small batches and distributed to trained or licensed skin therapists, spas and salons to be supplied with professional advice on their use
    (OTC products are made for the masses and sold in department stores and supermarkets)
  • contain small molecule technology for dermal and epidermal penetration
    (OTC products that lack active ingredients, have large molecules which are not able to penetrate the skin. When a product can’t properly penetrate the skin, it will only “superficially” treat and temporarily provide relief to skin concerns. This gives the illusion that the products are working without actually treating the skin. Professional lines use molecular technology that penetrates the skin producing clinical results)
  • are packaged in airless pump packs to eliminate spoilage of ingredients  when exposed to the air
  • have pH balanced and adjusted ingredients – skin functions at its prime when the natural pH is between 4.5 and 5.5.
    (Often OTC products don’t take pH into consideration and will leave the skin in an alkaline state. When the skin is alkaline, bacteria and free radicals (such as pollution) can invade the skin)
  • do not contain unnecessary fillers and preservatives

Professional skincare often has a reputation of being “too expensive” but that is more often than not actually far from the truth. A good professional line will price their products according to the concentration of active ingredients versus fillers and are actually overall more budget-friendly. It is a common mistake to overuse products which leads to the perception that professional skincare is more expensive. Our Skin Specialist will advise you on the appropriate amount and when to use the products according to your skin condition and type.

When used properly, professional skincare products will last longer and work better giving you the ultimate bang for your buck. OTC products will have a lower upfront cost but over time can be similar in price or more expensive than professional skincare and won’t actually repair the skin condition being treated.
