Collagen vs Glutathione

If you're struggling with dull, aging, or uneven skin, you've likely heard of collagen and glutathione. But which one is right for your skin goals?

You hear a lot about collagen and glutathione these days - especially from manufacturers of skincare products. Collagen is an essential building block of skin and helps improve its firmness and elasticity. Glutathione is an antioxidant that is essential for maintaining the structural integrity of connective tissues in the skin.

The argument of collagen vs glutathione is most certainly a subjective one. The nutrient that will be best for your skin will depend largely on what your goals for your skin are, the type of skin issues you are facing, and your individual health status.

Still, there are things that you need to know about both of these nutrients that will help you determine which one you should be incorporating into your skincare routine, when you should use them, and what to expect from them. In the following post, we will be talking all about collagen vs glutathione for skin.

TL;DR for "Collagen vs Glutathione for Skin"

  • Collagen supports elasticity and hydration in skin.
  • Glutathione brightens the complexion and reduces oxidative stress.
  • Both contribute to anti-aging, skin rejuvenation, and improved skin texture.
  • Taking collagen and glutathione supplements together enhances skin health.
  • Both have minimal side effects; collagen may cause bloating, and glutathione may lead to nausea.
  • Best to take them on an empty stomach for optimal absorption.

Collagen Vs Glutathione: Comparative Benefits

Benefits of Collagen and Glutathione Benefits of Collagen and Glutathione

To start, we are going to get right into the collagen and glutathione together benefits and compare them side-by-side:

Collagen Benefits Glutathione Benefits
Elasticity - There have been several studies that confirm that adequate levels of collagen in the skin can improve its elasticity - the manner by which it can stretch and return to its normal form (Ref). Collagen is essential for the structural support of the skin, which allows it to have elastic qualities. Powerful Antioxidant - Glutathione is classified as a potent antioxidant for skin. This means that it can help scavenge and neutralize free radical cells before they can damage the skin. Glutathione may also reduce the amount of oxidative stress that your skin endures and reduce the signs of oxidative damage.
Skin Rejuvenation - Collagen production starts to ebb with age. The older you get, the less collagen your skin is likely to produce. This can result in dull-looking skin, sagging, drooping, rough texture, and other unwanted issues. Collagen works to rejuvenate the skin and give it a more youthful appearance. Brightening the Skin’s Complexion - Glutathione has been observed to inhibit the functions of an enzyme known as tyrosinase, which can increase the amount of melanin in your skin. By reducing melanin, glutathione can make your complexion appear brighter and reduce the likelihood of developing dark spots and hyperpigmentation.
Anti-Aging Effects - Collagen has also been observed in high-quality clinical studies to delay certain signs of skin aging (Ref). The National Institutes of Health has stated that “Both oral and topical collagen can contribute to reducing or delaying skin aging.” This means that whether you use a cream or serum that contains collagen, or take collagen in capsule form, it can help delay the appearance of signs of skin aging. Anti-Inflammatory Action - Glutathione also has anti-inflammatory properties that protect the skin. Skin inflammation can result in visible marks and over time, can cause premature signs of skin aging. By reducing inflammatory markers in the skin, glutathione can help keep your skin looking young.

Sarah Smith

Sarah Smith, Board-Certified Dermatologist with expertise in Medical Affairs and Clinical Development, says that "Glutathione plays a critical role as a powerful antioxidant in the body, crucial for maintaining the structural integrity of skin, reducing oxidative stress, and promoting skin health."

Can I Take Collagen and Glutathione Together?

The short answer to this question is yes. Collagen and glutathione are both natural substances that are produced by the body - albeit in different parts. Still, as natural components of human skin, they can be safely used together in a supplemental or topical manner.

In fact, many experts advise that you take glutathione and collagen together as they have similar benefits on the skin and don’t appear to cause any adverse interactions with one another.

It is typically suggested that you use a supplement that contains both glutathione and collagen, as this will make it easier to reap the skin-improving benefits of both nutrients. They can also be taken together in the form of a cream or serum, depending on which method your skin tolerates best.

Collagen and Glutathione Supplements

A lot of people opt for collagen and glutathione supplements simply because they make it much more convenient. With a good collagen and glutathione supplement, you can dial in exactly how much of these nutrients your skin is getting on a daily basis.

This is the quickest way to:

  • Yield results that you can actually notice
  • Keep track of the progress that the nutrients are producing for your skin
  • Make sure you are getting the right amount of these nutrients on a daily basis

Also, glutathione and collagen supplements may be absorbed into the skin better than some creams or serums. That’s because the processing, manufacturing, and delivery systems for some serums and creams may dilute these nutrients and cause delayed or even inadequate absorption into the skin.

When is the Best Time to Take Glutathione and Collagen?

The best time to take glutathione and collagen will depend on the unique needs of your skin. If you are taking supplements that contain these nutrients, it may be best to take them on an empty stomach so that they absorb completely.

Still, it is very important that you ask your trusted healthcare practitioner or dermatologist about when you should be taking your glutathione and collagen supplements for the best effects and based on your individual needs.

Supplements offer a great way to fine-tune your glutathione and collagen dosage and make it easier to track results. But be sure to keep your options open because, after all, the most important thing is to make sure that your skin is getting an adequate amount of collagen and glutathione.
