Collagen Skin Health: Key Amino Acids in Collagen for Skin

Collagen, the most abundant protein in our body, is often hailed as the cornerstone of skin health. Its intricate role in maintaining the elasticity, strength, and regeneration of skin has been a focus of interest in both the beauty and health industries. At the heart of collagen’s efficacy are specific amino acids that form its structure and function. These amino acids are not just building blocks; they are the architects of our skin’s resilience and youthfulness.

In understanding the importance of collagen for skin health, it's essential to delve into the key amino acids that make collagen more than just a protein - they make it a vital component of our skin's integrity and vitality. From providing structural support to aiding in hydration and repair, the amino acids in collagen have a profound impact on how our skin looks and feels.

As we age, our body's natural production of collagen decreases, leading to common signs of ageing such as wrinkles, dryness, slow wound healing, and loss of firmness. This reduction underscores the importance of collagen and its amino acids in maintaining skin health. By understanding the role of these amino acids, we can better appreciate and support our skin’s need to maintain its health and appearance.

In this article, we will explore the key amino acids in collagen that are critical for skin health, their unique properties, and how they contribute to maintaining the skin's youthful glow and elasticity.

The Science of Collagen and Skin Health

Collagen is not just a buzzword in the beauty industry; it's a fundamental component of our skin's structure. Think of collagen as the scaffolding of the skin, providing both strength and flexibility. This protein is composed of long chains of amino acids that form a unique triple helix structure, giving it remarkable tensile strength and the ability to maintain skin firmness and elasticity.

As we delve into collagen's role in skin health, it's important to understand that collagen isn’t just one uniform substance. It exists in several forms, but in the skin, Type I collagen predominates, providing the skin with its structure and firmness. Another vital aspect of collagen in skincare is its form as peptides. Collagen peptides are smaller units of protein that are more easily absorbed by the body compared to the whole collagen molecule. These peptides are what the body uses to signal the production of new collagen, making them crucial for skin repair and rejuvenation.

Key Amino Acids in Collagen: Glycine, Proline, and Hydroxyproline

The efficacy of collagen lies in its amino acid composition, particularly glycine, proline, and hydroxyproline. These three amino acids are predominant in collagen and play a pivotal role in skin health:


The simplest of all amino acids, glycine, constitutes about one-third of collagen. It is vital for constructing the DNA strands that are a significant part of skin cells, helping in the repair and protection process of the skin.


This amino acid works as an antioxidant, protecting the skin from damage by free radicals. Proline also helps in the production of new collagen and can assist in the healing of skin wounds.


Derived from proline, hydroxyproline is critical for stabilising the collagen triple helix. It's essential for keeping the skin moisturised and aiding in the production of more collagen, thereby contributing to the skin's overall structure and preventing sagging and wrinkles.

The Superiority of Bovine Beef Collagen Peptides

When considering collagen supplementation for skin health, the source of the collagen is paramount. Bovine beef collagen, particularly in peptide form, stands out as a superior choice. Bovine collagen is predominantly Type I and Type III, closely mirroring the type found in human skin, which makes it highly compatible and effective for skin health.

The benefits of bovine beef collagen stem from its high content of the key amino acids - glycine, proline, and hydroxyproline - which are crucial for maintaining the skin's elasticity, moisture, and overall appearance. These amino acids in bovine collagen help stimulate the body's own collagen production, a vital process that diminishes with age.

Regular supplementation with bovine collagen peptides can replenish these essential amino acids, aiding in reducing signs of ageing, such as fine lines and wrinkles, and improving skin hydration and texture.

Cell Squared's Commitment to Quality

Our commitment to quality is unwavering, especially when it comes to our Beef Bovine Collagen Peptides Powder. We take pride in offering a product that not only supports your skin health but also aligns with the highest standards of purity and efficacy. Here’s what sets our collagen powder apart:

CellTomic™: Ultra Low Molecular Weight for Optimal Absorption

Our unique CellTomic™ technology ensures that our collagen peptides have an atomic molecular weight of just 960 Daltons. This ultra-low molecular weight is a game-changer in terms of absorption and bioavailability.

Unlike standard collagen products, which typically range from 2000 to 6000 Daltons, our collagen peptides are highly absorbable. This means that your body can more efficiently uptake and utilise the full spectrum of the 18 amino acids present in our collagen, maximising the potential benefits for your skin and overall health.

Comprehensive Amino Acid Profile

Cell Squared's Bovine Beef Collagen Peptides Powder is a rich source of essential amino acids, including Glycine, Proline, Hydroxyproline, Glutamic Acid, Alanine, Arginine, Aspartic Acid, Lysine, Leucine, Serine, Valine, Threonine, Isoleucine, Phenylalanine, Hydroxylysine, Histidine, Methionine, and Tyrosine.

Each of these amino acids plays a critical role in maintaining and enhancing your skin’s elasticity, firmness, and hydration, as well as supporting other aspects of your health like gut, muscle, and bone wellness.

Pure and Natural Quality

Our commitment to natural, bio-available amino acids means our collagen is free from GMOs, Glyphosate, pesticides, antibiotics, and hormones. This purity is essential not only for your health but also for ensuring the highest efficacy of our product. We source our collagen from 100% grass-fed and finished cows in Australia, adhering to sustainable and ethical farming practices.

Incorporating our unflavoured Bovine Collagen Peptide Powder into your daily routine is a straightforward step towards a more youthful, vibrant, and healthy skin appearance. Its unflavoured nature allows for seamless integration into various parts of your diet.
