Biotin VS Collagen VS Hyaluronic Acid: Introduction

What Is Collagen?

Collagen is one of the most essential proteins in humans’ and animals’ connective tissues. It makes up most of the protein in our bodies, making it the most prevalent protein in mammals. Numerous tissues, including skin, bones, tendons, ligaments, cartilage, blood vessels, and organs, rely on collagen for structural support and strength.

Various types of collagens are found throughout the body, each with specific functions and distribution. Some of the main types of collagens include:

  • Type I: Found in skin, bones, tendons, ligaments, and other connective tissues. It provides strength and support.
  • Type II: Predominantly found in cartilage, which cushions and protects joints.
  • Type III: Found in skin, blood vessels, and internal organs. It helps support the structure of organs and tissues.
  • Type IV: Present in the basement membrane of epithelial tissues, providing a framework for cell adhesion.

What Is Biotin?

A water-soluble B vitamin with other names, including vitamin B7 or vitamin H, biotin is essential for several metabolic processes in the body. For example, it plays a crucial role in the metabolism of fats, carbohydrates, and proteins. And D-Biotin is necessary for synthesizing fatty acids, glucose, and amino acids. These are essential for energy production and maintaining a healthy metabolism.

D Biotin is part of the B-complex group of vitamins. As a crucial nutrient, the body cannot make enough of it, and must be received through diet.

Its CAS number is 58-85-5. And D-Biotin chemical structure is C10H16N2O3S, with its formula weight of approximately 244.31 g/mol.

What Is Hyaluronic Acid?

The human body naturally contains hyaluronic acid, primarily found in the skin, joints, and connective tissues. It is a specific kind of glycosaminoglycan, a polysaccharide with a long chain of sugars that is an essential part of the extracellular matrix. This web supports the structural integrity of cells within tissues.

Comparison: Biotin VS Collagen VS Hyaluronic Acid On Skin

D Biotin, an essential vitamin, is necessary for maintaining good health. Collagen, a protein, can be produced naturally. Next, we will compare the two ingredients, mainly in terms of skin and hair.

Biotin VS Collagen On Skin


  • They are both involved in keratin production. Keratin is a protein that is a major component of hair, skin, and nails.
  • They play a role in maintaining the health and strength of the connective tissues in the human body.
  • They are important for maintaining a healthy metabolism.
  • They are both commonly used in beauty and skincare products.

Overall, vitamin H biotin and collagen are essential for maintaining healthy skin, hair, and nails. D-Biotin is often referred to as the “beauty vitamin” as it helps to strengthen and promote the growth of hair and nails. On the other hand, collagen is a protein that provides elasticity to the skin, hair, and nails.


  1. D-Biotin helps convert amino acids into keratin, while collagen provides the building blocks for keratin production.
  2. Biotin helps to support the production of collagen. It is essential for maintaining the integrity of the skin, joints, and bones.
  3. Vitamin H is involved in metabolizing carbohydrates, fats, and proteins. At the same time, collagen helps to support a healthy metabolism by promoting the growth of lean muscle mass.
  4. D Biotin is often included in hair and nail supplements, while collagen is a popular ingredient in anti-aging skincare products.

Biotin VS Collagen For Hair


Both these two ingredients are essential for maintaining healthy hair growth.

  • They can help improve hair thickness and volume.
  • They play a role in preventing hair breakage and damage.
  • They help improve the overall health of the scalp.


  1. Vitamin B7 supports hair health by breaking down macronutrients for cell renewal and growth. Conversely, collagen promotes hair follicle growth through amino acids and proteins, strengthening the scalp’s dermis and fighting free radicals. In other words, it provides strength and elasticity to the hair follicles.
  2. The former promotes the production of fatty acids in the scalp, nourishing hair follicles and encouraging hair growth. As a structural protein, collagen strengthens the hair shaft and adds volume to the hair.
  3. The former strengthens the hair strands, making them less prone to breakage and splitting. The latter improves the hair’s elasticity, reducing the risk of breakage caused by external factors like heat styling or chemical treatments.
  4. D Biotin helps in the production of sebum. It is a natural oil to moisturize the scalp and prevents dryness. And collagen improves blood circulation in the scalp, ensuring proper nutrient supply to the hair follicles.

However, the efficacy of biotin as a hair growth vitamin has yet to be scientifically proven. Preliminary studies suggest that biotin can boost hair growth, but conclusive evidence still needs to be provided. Some patients taking biotin supplements may see improvements in their hair health.

Hyaluronic Acid VS Collagen

Pure hyaluronic acid, a natural ingredient, successfully lowers wrinkles’ appearance and fine lines by increasing skin hydration levels. It is found in high concentrations in the skin and can be separated into solutions with different molecular sizes. A more excellent molecular weight form of hyaluronic acid offers a moisturizing cushion that fills in the appearance of wrinkles.

The hyaluronic acid powder is typically a vegan ingredient, produced using bio-fermentation, making it an excellent choice for natural skincare products. However, brands should double-check with their suppliers, as some animal versions of hyaluronic acid exist, such as snail mucin, which is reserved for medically injectable products.

While collagen, a large molecule, doesn’t penetrate the skin layers when used topically and doesn’t act as mechanical scaffolding to create structure, elasticity, and firmness. It is a vital component of the skin’s connective tissues and helps keep the skin firm and elastic. However, it is not a vegan ingredient, so it’s not a good choice for plant-based skincare products.

Various types of collegen supplemnt are found throughout the body, each with specific functions and distribution. Many supplements are available in the market that are dematologist approved collagen supplements that you can also look for.


In conclusion, D biotin and collagen are essential nutrients for maintaining good health, with biotin supporting healthy hair, nails, and skin. It plays a role in building keratin, which contributes to skin structure. It also promotes healthy skin and nails. Biotin supplementation may improve certain skin conditions.

Collagen, a protein produced naturally, keeps the skin’s structural integrity and increases its strength and suppleness. It improves skin elasticity and hydration. It supports skin barrier function and protects the skin from external environmental factors.

The two raw ingredients mentioned above help hydrate the skin, minimizing fine wrinkles and improving skin conditions. However, the efficacy of biotin as a hair growth vitamin has yet to be scientifically proven.

As a natural ingredient, hyaluronic acid powder effectively reduces fine lines and wrinkles by increasing skin hydration levels. It is found in high concentrations in the skin and can be separated into solutions with different molecular sizes. A greater molecular weight of hyaluronic acid is more likely to improve skin elasticity and reduce fine lines.
