Collagen For Skin


Collagen – a protein located on the surface of skin – is key to having a youthful and healthy look. As we age, collagen levels can drop, leading to wrinkles and other aging signs. Taking collagen supplements can help bring collagen levels back up, allowing skin to appear younger and more vibrant.

Let us have a better look at what collagen can do for skin:

What is Collagen?

Collagen is a protein-filled substance found in many parts of the body. It is mainly in connective tissue, muscles, bones, and skin. People often call it the “glue that holds everything together“. It helps the skin stay firm and elastic, giving it a youthful look and helping wounds heal. Collagen supplements are popular for aging skins.

Animals like humans, fish, chickens, pigs, cows, and even squid have collagen. The most studied is type 1. It has two subtypes: I-I (from human tissues) and I-III (from bovine tissues). Collagen I-III from bovine tissues are frequently used to supplement skin health because it’s similar to human collagen.

When buying supplements, it’s important to pick high quality sources. Low quality sources might have contaminants that could hurt you or not be effective.

Benefits of Collagen for Skin

Collagen is a key part of connective tissues like skin, tendons, and ligaments. It’s like a scaffold to keep us together and has many advantages for skin health and a young look. Here are some of the benefits of taking collagen supplements for skin:

  • Strengthens the outer layer of skin, preventing sagging, wrinkles, and thinning.
  • Gives hydration to skin cells, making wrinkles look fuller and more youthful.
  • Repairs damaged skin and provides antioxidants for protection from UV radiation damage.
  • Helps make elastin in the body, resulting in firmness and elasticity in the inner skin layer.
  • Acts as an anti-inflammatory, which can lower redness and irritation from environmental stressors. It can even lower acne flare-ups.
  • Has vitamins and active compounds like vitamin A to stimulate cell renewal for a smoother complexion.

Types of Collagen

Collagen: It’s a protein! Found in the body, it’s the most abundant protein around. Different types exist – Type I, Type III and more – each with its own special characteristics and functions.

Type I Collagen? It gives structure and strength to organs. Type III collagen? It supports the skin and other tissues.

What skin benefits can collagen offer? Let’s explore together!

Type I Collagen

Type I collagen is the most common. It’s found in skin, ligaments, tendons, organs and bones. It gives strength and flexibility to these tissues. The fibrils are 10-100 nanometers wide. They are made of three polypeptide chains – two alpha-1 and one alpha-2.

Type I collagen is also needed for the formation of new blood vessels. This is key for wound healing. In the dermal layer of skin, it makes up 80-90% of the structural protein. With age, we make less collagen and wrinkles form as a result.

Type II Collagen

Type II collagen is one of the five main types of collagen and is the most common in humans. It’s found in articular cartilage, which covers bones at joints providing shock absorption for movement. With age, less type II collagen is produced, leading to joint degeneration and pain – osteoarthritis.

Type II collagen binds chondrocytes – cells forming healthy cartilage. It also supports production of hyaluronic acid (HA), lubricating our joints and cushioning movements. It has antioxidants to protect cartilage and heal damaged cartilage faster.

This type of collagen is derived from chicken sternum and feather extracts. It’s absorbed swiftly due to its small molecular size, enriching skin with amino acids, supporting our body’s connective tissue. Dietary supplements containing type II collagen can restore youthful firmness to skin and reduce wrinkles, stretch marks and other signs of aging, an ideal anti-aging routine!

Type III Collagen

Type III collagen makes up only 2-3% of the total collagen in our body, yet it is essential for skin health. It provides structure, increases elasticity and strength, and helps prevent water loss from the skin. Fibrous collagen networks link to proteins, forming a protective scaffolding. Elastin fibers work with type III collagen to maintain firmness and suppleness of skin.

This protein also repairs tissues when injured or infected. Type III collagen also acts against oxidative damage, reducing free radical damage and protecting cellular integrity. It is abundant during development, but decreases with age. Adults may need to supplement it to achieve healthy skin.

Type IV Collagen

Type IV Collagen is a vital and widely researched sort of collagen. It’s found in various body areas such as the dermal layer of the eggshell membrane, vessel walls, and the vitreous humour levels of the eyes. It makes a strong mesh-like structure that adds stability and strength to tissues. Type IV Collagen gives support for immunity cells, without it we’d be more exposed to sickness.

At a molecular level, Type IV Collagen consists of 3 “alpha chains“. These form two distinct domains: an N-terminal domain (headpiece) and a C-terminal domain (tailpiece). Both regions give balance to other molecules inside this type of collagen. Plus, its network framework helps with filtration; stopping some molecules from leaking out and allowing others to pass through.

For skin health, Type IV Collagen has several roles. It provides structure for skin cells, keeping them hydrated and reducing wrinkles and age spots. Plus, its filtration abilities (with other components) shield our skin from UV radiation and microbial infections that come through wounds or cuts.

Type V Collagen

Collagen is a chief structural protein found in skin, bones, and join tissues all over the body. It gives the skin a smooth, firm, and hydrated look. Although the body naturally produces collagen, it decreases with age, resulting in wrinkles and drooping skin.

Type V collagen is one of 28 kinds of collagen. It makes the skin firm, strong and flexible. It supports structures made by other collagen types. Type I attaches to the basement membrane zone, thus helping repair harm caused by physical shock or burns. Type V collagen is seen in aged connective tissue, restoring elasticity between fibers.

Type V collagen, when applied topically, can reduce wrinkles better than other materials because it can penetrate the skin better. Taking it orally stimulates production of type V collagen. It fights aging signs like dryness, dullness, and fine lines, plus improving overall complexion. Researchers think that due to its anti-oxidative effects, type V collagen limits melanin production around the eyes, resulting in brighter looking undereyes and smoother skin.

Type VI Collagen

Type VI Collagen is a unique kind of collagen found in skin, tendons, and other connective tissues. It is made up of three amino acid chains bonded by hydrogen. This type of collagen is found in high concentration in the extracellular matrix. It helps maintain the structure and function of the dermal matrix. It connects with proteins such as elastin and fibrillin, to keep skin elastic and firm.

Type VI Collagen gives strength to the skin barrier. When its production decreases, due to age or genetics, the skin barrier may weaken. This can cause premature aging signs, like wrinkles and sagging skin.

To boost collagen production, one can change their lifestyle or take supplements. This can help enhance the skin barrier and improve skin health and appearance.

Sources of Collagen

Collagen is great for skin. But, it can be hard to get enough from food. Have no fear! There are many sources – natural and man-made. Let’s learn about them so you can pick the best choice:

Foods Rich in Collagen

Collagen is essential for skin structure. It’s a protein found in connective tissues beneath the skin. Collagen decreases with age, but there are foods to help replenish it. Here are natural sources of collagen:

  • Fish like salmon, sardines and cod contain proteins that support collagen growth.
  • Bone broth has anti-inflammatory properties and strengthens bones. It’s full of amino acids that boost collagen too.
  • Citrus fruits are high in vitamin C, a powerful antioxidant that aids in collagen production.
  • Berries like blueberries and blackberries are full of antioxidants that help create collagen.
  • Eggs contain proteins that promote healthy muscles, including collagen.
  • Leafy greens like kale, spinach and collard greens are packed with phytonutrients that restore dermal balance and support skin cell structure.

Incorporating collagen-rich food into your diet will help you maintain a youthful, wrinkle-free complexion with improved firmness over time.


Gettin’ your collagen levels up? Supplements are here to help! You can choose from capsules, powder, or liquid. Powders and liquids require more mixing, but they dissolve in water more easily.

Pick a supplement that has quality ingredients like hydrolyzed collagen peptides, vitamins A, C, and E, hyaluronic acid, and antioxidant-rich extracts. Watch out for allergens like dairy and nuts if you are restricted. Then you’ll really get the most out of your supplement!

How to Use Collagen for Skin

Collagen is a natural protein that helps keep skin looking youthful and supple. It’s a vital part of the body’s connective tissues, which give structure and strength to the skin. As we age, collagen production decreases. So, it’s important to know how to use collagen to maintain healthy and vibrant skin.

Here are the ways to make use of collagen for skin care:

Topical Applications

Applying collagen topically can help with wrinkles and fine lines. Collagen is too big to absorb through the skin, so it must be broken down into smaller particles. Collagen creams use ingredients like hydrolyzed collagen or peptides for absorption. Serums contain nanoparticles and micronutrients to nourish your skin cells.

Plus, collagen creams usually have other active ingredients like antioxidants and vitamins. These work together to reduce wrinkles and protect the skin from environmental stress.

To get the most out of your collagen cream, apply it twice daily on cleansed skin. It should be hydrating but not greasy. Also, wearing SPF 30 sunscreen year-round can protect your skin from sunburns and UV damage.

Oral Supplements

Oral supplements come in capsules or powders. They have a high concentration of collagen peptides. Different brands offer different levels of collagen protein like bovine or fish-based. Supplements are easier to consume and are accessible to anyone wanting to benefit from collagen.

These peptides can stimulate skin fibroblasts. This increases the rate of skin regeneration, giving clarity and firmness to the complexion. It also reduces wrinkles and improves skin elasticity.

It’s important to be consistent and follow the manufacturer’s guidelines when using an oral supplement. The doses vary but taking one teaspoon each day will help your skin health.


Collagen injections can treat wrinkles, scars and other skin issues. But, it’s pricey and you might feel soreness and bruise at the injection site. Depending on your skin concerns, you may need several treatments.

Your doctor or dermatologist will use a fine needle to inject purified bovine (cow) or human-sourced collagens under your skin. After the injections, you’ll witness improved skin tone and smoother look.

It might take a few treatments to get the desired result. If you’re allergic or have sensitive skin, make sure to tell your doctor before the treatment.

Side Effects

Collagen is a protein made naturally by the body. It can also be taken as a supplement. It’s said to help skin elasticity, reduce wrinkles and slow aging. Taking collagen supplements can be beneficial, but it can cause side effects. Here, we’ll look at these possible side effects:

  • Nausea
  • Stomach pain
  • Headache
  • Heartburn
  • Joint pain
  • Muscle pain

Allergic Reactions

Allergies are an uncommon result of taking collagen supplements. The proteins in collagen come from animals and insects, so they may bring on an allergic reaction in some people.

Signs of this could be hives, rashes, itching, swollen eyes and lips, sneezing, and a stomach ache. If your throat is swelling or you have a hard time breathing, this is a critical emergency, and you need help right away.

If you’re having a reaction after taking the supplement, quit using it and see a doctor ASAP. Your doctor can check if you’re having an allergic response and give you the right treatment, based on the reaction’s severity. They might also do a blood test to figure out which supplement ingredient caused the allergy, so you can avoid it in the future.

Digestive Issues

Collagen is often used in skincare to reduce the look of wrinkles and stretch marks. Plus, it’s become a popular supplement to help with digestion and healthier skin, hair, nails and bones. Generally, it has no adverse side effects. But, some may have bloating, gas or an upset stomach.

If you already take meds for digestive issues, like IBS or Crohn’s, ask your doctor before trying collagen. It’s protein-rich and full of amino acids. Your body needs to break these down into small molecules, so they can be absorbed. If your body has trouble, you may get abdominal pain, nausea or constipation.

To get the most out of collagen, start with small doses and increase until you reach your optimal dose. Also, drink lots of water to help your body digest and absorb, while avoiding any potential digestive discomfort.

Skin Irritation

Skin irritation is the most frequent side effect of collagen supplements, both oral and topical. The topical kind may cause a mild tingling or burning feeling on the applied area. Taking oral collagen may lead to nausea, heartburn, and indigestion. Those with seafood allergies should usually avoid such supplements.

If you worry about taking or using collagen, you should consult your doc or dermatologist. They’ll help you figure out if the collagen product is safe and give advice to reduce any side effects.
