Amino acids are gaining popularity for their skin benefits and safety. You can use amino acids for skin rejuvenation and hydration. They are scientifically proven to be effective in solving skin care woes.
Amino acids help restore cracked, flaky, or dry skin and maintain overall skin health. They work much better than any other fancy ingredient you might have heard of. This article explains the benefits of amino acids, how to use them, and their potential side effects. Keep reading to know more.
What Is It?
The building block of proteins. It includes proteins in the skin, such as keratins, collagen, and elastin.
What Are Its Benefits?
It has antioxidative, anti-inflammatory, and anti-aging properties that may improve skin hydration, and reduce fine lines.
Who Can Use It?
It can be safely and effectively applied to the skin.
They are mostly safe to use every day, provided they’re not applied excessively.
It may cause skin irritation, therefore, a patch test is recommended before using it.

What Are Amino Acids?
Amino acids are the organic compounds that combine to form proteins. They are left behind after proteins break down. The human body uses amino acids to make proteins to perform various functions (1).
Amino acids also play a role in maintaining overall skin health and appearance. These amino acids can be segregated into two major categories:
- Essential Amino Acids
Essential amino acids are those not produced by the body. You can only get their benefits from eating certain foods or supplements. Examples of essential amino acids include leucine, isoleucine, phenylalanine, histidine, threonine, lysine, methionine, tryptophan, and valine. They are found in animal meat (beef, poultry, seafood), animal products (dairy, eggs), and certain high-protein plant foods (nuts, legumes, soy products, and beans) (2).
- Non-Essential Amino Acids
Non-essential amino acids are produced by the body. These include alanine, aspartic acid, cysteine, glutamic acid, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, serine, proline, glycine, and tyrosine. Most healthy adult bodies make these amino acids naturally (3).
Amino acids are a natural part of the skin and help keep it hydrated and supple. They also make up collagen, which is a part of various connective tissues, muscles, and tendons. Collagen is also present in the skin (4).
In the next section, we discuss the key benefits of amino acids for the skin.
Key Benefits Of Amino Acids For The Skin
The key benefits of amino acids in skincare include promoting cellular repair, increasing skin moisture, stimulating collagen production, etc. We have further elaborated on these benefits below.
- Hydrate The Skin
The skin’s top layers contain amino acids that help keep the skin hydrated. They also help treat skin dryness, acne, and rough texture (5).
- May Protect Skin Against Damage
Amino acids help protect skin by promoting cellular repair, boosting hydration, and offering antioxidant protection (6).
- May Enhance Water Retention
Amino acids, used in conjunction with other ingredients like glycerin and hyaluronic acid, plump the skin by helping boost moisture (7). It is believed that amino acids, when used with hyaluronic acid, may help fight the signs of aging (8).
- Help Build Collagen
Studies suggest that amino acids help restore collagen synthesis that otherwise would have been impaired by UV radiation (9).
- Help Smooth Fine Lines
Amino acids may help make the skin firmer and diminish fine lines and wrinkles (10). Their ability to promote collagen production may also have a role to play here.
- Promote Cellular Repair
Amino acids are easily absorbed from topical creams and help stimulate collagen production. Certain amino acids also reduce inflammation and promote skin repair (11).
These are the major benefits of using skin care products with amino acids. That said, these acids may also cause certain side effects.
Side Effects Of Using Amino Acids
Amino acids usually work well for most skin types and are generally safe. However, do exercise caution while introducing them to your skincare routine. Perform a patch test before using the product. Stop use if you observe any reaction.
The next section will discuss the ways to use amino acids for better, healthy-looking skin.
How To Use Amino Acids For Smoother Skin
The safest and easiest way to reap the benefits of amino acids is through your diet. You may start consuming various dietary sources of amino acids.
Protein also contains all nine essential amino acids. These complete proteins include meat, fish, eggs, poultry, and dairy. Essential protein options for vegans include buckwheat, soybeans, and quinoa.
In addition, amino acids must also be an essential part of your daily skincare regimen. The most common source of amino acids is facial creams, especially those meant for sensitive areas (like the area around the eyes). If you want to introduce facial creams rich in amino acids to your skincare routine, start with a moisturizer or eye cream. Some of the amino acids to look for in skincare include lysine, arginine, histidine, glycine, and leucine (9).

Amino acids are organic compounds that hydrate the skin, promote cellular repair, and reduce fine lines and wrinkles. You can either consume foods rich in amino acids or use cosmetic products with amino acids to get smooth and healthy skin. We have listed a few amino acids you must include in your skin care routine. Check out the infographic below to know more!
Amino acids are organic compounds used to make proteins in the body. Non-essential amino acids such as glutamic acid are produced naturally in the body while essential amino acids such as leucine are obtained through foods such as dairy products and plants. The benefits of amino acids for your skin include skin hydration, protection against UV rays, and production of collagen. While amino acids are safe for all skin types, conduct a patch test before using any amino acid product. If you experience any adverse effects, stop using it immediately.
