Amino acids for skin: 5 benefits and how to use

Finding the ideal skincare routine can seem like an endless struggle. Just when you think you have figured it out, a new issue or concern appears. Plus, there are far too many skincare products available that make things even more confusing. To make things easier for you, here is a suggestion: try incorporating amino acids in your skincare routine. Amino acids, also known as the “building blocks of life,” play an important part in many body functions. They can also be a game changer in your skincare routine. It helps cracked, flaky, or dry skin while also maintaining overall skin health. Know the benefits of amino acids for skin and how you can use it.

What are amino acids?

Amino acids are small chemical substances that combine to produce proteins. The body employs these proteins to aid in various physical processes, including breaking down food particles, strengthening muscles, boosting immunity, and repairing damaged body tissue. Most importantly, amino acids help retain healthy skin.

There are two kinds of amino acids: essential and non-essential. The non-essential amino acids can be produced by your body, whereas the essential amino acids must be obtained through food or supplements. The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, as found in a study published in StatPearls. These are commonly found in animal protein-containing goods such as fish, poultry, dairy products, and eggs, but they can also be found in crops like quinoa and soy products.

Benefits of amino acids for skin

Amino acids play a crucial role in skin health. Here are some key benefits of amino acids for your skin.

1. Increases collagen and elastin production

Amino acids, particularly glycine, proline, and lysine, are essential for the synthesis of collagen and elastin, as found in a study published in amino acids. These proteins provide structure, elasticity, and firmness to the skin. A decrease in collagen and elastin production is a major contributor to ageing. Consuming foods rich in these amino acids can help maintain youthful skin.

2. Heals wounds

“Amino acids promote the growth and proliferation of skin cells, aiding in the healing process. They also contribute to the formation of new tissue, helping to close wounds and reduce scarring,” explains dermatologist Dr Ruben Bhasin Passi.

3. Hydrates the skin

Amino acids act as moisturising agents, drawing and retaining hydration within the skin’s outermost layers. This is crucial, as chronic dryness can lead to skin problems like acne, skin irritation, and premature ageing, as found in a study published in the Journal of Cosmetic Dermatology. By enhancing water absorption, amino acids synergize with other hydrating ingredients, such as hyaluronic acid. As key components of the Natural Moisturizing Factor (NMF), they help the skin seal in moisture, resulting in smoother, healthier skin that is less prone to dryness and wrinkles.

4. Protects you from sun rays

Certain amino acids, like tyrosine, have antioxidant properties that can help protect the skin from damage caused by harmful UV rays. Antioxidants neutralise free radicals, which can contribute to premature ageing and skin damage, found a study published in the Pharmacognosy Review.

5. Has anti-inflammatory effects

“Some amino acids, such as arginine and glutamine, have anti-inflammatory properties which help to reduce inflammation. Also, they can help to soothe skin conditions like eczema, psoriasis, and acne, which are often associated with inflammation,” explains the expert.

Best amino acids for skin

Although all amino acids have a role in generating and maintaining smooth, healthy, younger-looking skin, some are preferred more in skincare products than others:

• Arginine helps restore visible skin damage.
• Histidine contains antioxidant properties that help to soothe the skin.
• Methionine neutralises harmful chemicals before they reach the skin, protecting it from damage.
• Lysine helps the skin by visibly firming the surface of the skin and boosting its supporting aspects.
• Proline, leucine, and glycine reduce fine lines and wrinkles.

How to use amino acids for skin?

You can get the benefits of amino acids through food. You may begin to consume various amino acid-rich foods. Protein also comprises the 9 essential amino acids. These complete proteins include fish, eggs, chicken, and dairy. Vegan protein sources include buckwheat, soybeans, and quinoa. Other ways to incorporate amino acids into your daily routine include:

• Serums and moisturisers: Look for products specifically formulated with amino acids. These can provide a targeted delivery of nutrients to your skin.
• Face masks: Sheet masks or clay masks containing amino acids can offer a concentrated dose of hydration and nourishment.
• Sunscreens: Some sunscreens incorporate amino acids to provide additional protection against UV damage and promote skin repair.
• Collagen supplements: Collagen is a protein rich in amino acids, including glycine, proline, and hydroxyproline. These amino acids are essential for skin health and elasticity.
• Amino acid supplements: Consider taking a supplement containing a blend of essential and non-essential amino acids. However, it is always best to consult a healthcare professional before starting any new supplement regimen.

Note: When choosing amino acid-based goods, look for formulations containing a variety of amino acids, including:

• Glycine: It helps to keep skin hydrated and elastic.
• Proline: It is involved in collagen synthesis and wound healing.
• Arginine: It promotes blood flow and collagen formation.
• Lysine: It is required for collagen and elastin production.

Incorporating amino acids into your skincare routine can help enhance the overall health of your skin and keep it more moisturised.

What are the side effects of amino acids for skin?

While amino acids are generally considered safe for skin, some individuals may experience side effects. These side effects are usually mild and temporary, but it is essential to be aware of these effects:

1. May irritate your skin

Topical application of amino acids, especially in high concentrations, can sometimes cause skin irritation, redness, or itching.

2. Allergic reactions

Some people may be allergic to specific amino acids. If you experience symptoms like hives, swelling, or difficulty breathing after using amino acid-containing products, discontinue use and seek medical attention.

3. Digestive issues

Consuming excessive amounts of amino acids through supplements or fortified foods can lead to digestive problems like nausea, vomiting, or diarrhoea. Synthetic amino acids cause acne majorly over back and chest in all age groups, excessive intake might cause weight gain, deranged blood work up, also a condition called hyperproteinemia.

Thus, it is highly recommended to consult with doctor before incorporating amino acids in your daily routine.
