For anyone looking to achieve radiant skin, you may be interested in hearing about a lesser-known compound that’s making waves in the world of skincare: spermidine. You might not have even heard of it, let alone its potential to give you a much-needed glow-up. Known for its anti-aging properties, spermidine is gaining attention as a key to youthful and healthy skin—a topic explored in depth by Healthnews. This article will dive into how spermidine might benefit the health of our skin, exploring its multiple ways of promoting a fresh-faced and radiant look.
What is spermidine?
All living cells contain spermidine. It’s a naturally occurring polyamine compound. And, it plays an important role in many cellular functions within our bodies, including:
- Cell growth
- Cell proliferation
- Cell regeneration
You can also find spermidine in lots of foods that many of us consume on a pretty regular basis, such as:
- Wheat germ
- Cheese
- Soy beans
- Mushrooms
- Cruciferous vegetables
- Tropical fruits like mango, pineapple, passionfruit
- Hazelnuts
Although spermidine is produced by our bodies, unfortunately it does naturally decline as we get older. This may lead to less effective cellular repair, which may also contribute to our skin looking more aged and less vibrant.
How spermidine benefits skin
Spermidine has been fairly well-researched for its potential age-defying effects. And, thankfully this extends to benefits for our skin too.
Anti-aging properties
One of the ways spermidine works is by promoting autophagy. From the perspective of skin health, this helps our bodies to remove old and damaged skin cells. It can then replace them with healthier and more youthful ones. This 2023 report highlights the potential of spermidine to delay some of the processes associated with aging. The authors also suggest that it has implications for use in therapeutic anti-aging strategies.
Another boost for spermidine's anti-aging potential comes from this 2024 randomized, controlled clinical trial. 41 participants between the ages of 30 - 63 were given either a spermidine containing supplement, or a placebo twice daily for two months. After the trial period, the supplement group had decreased their biological age by an average of 11 years. While this evidence seems incredible, it’s important to note that this trial was conducted with a blended supplement. So we can't attribute the results to spermidine alone.
Improves skin elasticity, hydration and firmness
It’s thought that spermidine may contribute to collagen synthesis. It might also help to enhance the elasticity, hydration and firmness of our skin.
This 2021 scientific review discussed how spermidine may contribute to improved elasticity and hydration. Researchers suggested this happens due to the way spermidine impacts the skin microbiome. It's also implied that it can promote collagen synthesis within skin cells
But, the authors recognized the need for further research. And, exact links between spermidine and skin health aren't fully established yet.
Reduces inflammation and redness
Inflammation is one of the hallmarks of aging. It can lead to redness, puffiness, and other inflammatory-related skin problems . These are all factors which can leave our skin looking lacklustre. Recent research suggests that spermidine may regulate inflammatory pathways in the body.
A 2021 interventional study explored the relationship between a diet rich in spermidine containing foods and anti-inflammatory markers. The results suggest that by consuming spermidine in foods like natto (a fermented soybean product), we may be able to reduce inflammation in our bodies. In turn, this may have a positive effect on our skin health.
Improves wound healing
The look and health of our skin can be negatively affected by wounds such as scratches, cuts, or pimples. Spermidine may possess the ability to speed up wound healing, potentially helping our skin to recover from damage quicker.
This 2021 laboratory study showed that treatment with spermidine accelerated wound healing. It also increased cell proliferation. However, this study was conducted in vitro in a lab. We need to recognize that the same effects might not be achieved simply by taking a spermidine supplement.
Protects against UV damage
There is some interesting, but fairly limited research into spermidine’s potential to protect against UV damage. In a 2022 study conducted on UV-B stressed barley seedlings, spermidine helped protect them against oxidative and UV-related damage.
While this line of investigation does hold some promise, we can’t apply the findings from a plant study to humans. There is a clear need for much more research in this area before we can make firm connections about spermidine and UV protection.
How to incorporate spermidine into your skincare routine
If you’re intrigued by how spermidine benefits skin and want to get more of it in your diet, here are a few options that you might want to try:
Dietary Sources: If you like making dietary changes, you can include more spermidine rich foods into your nutrition plan. It’s found naturally in wheat germ, soybeans, mushrooms, tropical fruits, cruciferous vegetables, and hazelnuts.
Supplements: If you are looking for a higher dosage, you might find that a spermidine supplement works better for you. Make sure you purchase a high-quality supplement, with accompanying evidence of how spermidine benefits skin. Make sure the product is well-reviewed and third-party lab tested. This ensures quality, purity, and maximum effectiveness.
Topical Applications: There are some skincare products that are starting to include spermidine in their formulations. However, research into the topical application of spermidine is still very much in its infancy. If you decide to go down this route, make sure you use a product from a well established and reputable brand.
Safety and potential side effects
Generally, it’s considered safe to use spermidine for its skin related benefits. But it’s always worth paying attention to any potential side effects. It may cause mild gastrointestinal discomfort in some individuals, especially if it’s taken in high doses.
As it stands, there’s not a great deal of human research into the safety and efficacy of spermidine supplements. So, it’s a good idea to check in with your healthcare provider before taking it. They’ll make sure that spermidine is safe for you and won’t interact with any health conditions or medications you might be taking. This is especially important for pregnant or nursing individuals, or those with pre-existing conditions.
Conclusion
Spermidine has some exciting potential benefits for the health and vitality of our skin. It may help with collagen production, elasticity, and hydration. But, as with many supplements, the research is still evolving. We can’t simply say that taking spermidine will magically turn back the biological clock.
Rather than looking towards a particular dietary addition as a skin savior, try to focus on a diet that supports overall healthy aging. Think about getting a wide variety of whole foods into your nutrition plan, including lots of fruits and vegetables. Spermidine should be included as an additional component to an already healthy diet rather than a sole solution for aging skin.
As an important final note, remember that aging is a completely natural process. And, it’s normal that our skin begins to change as we age. Getting older and wiser can be seen as a privilege to be admired and respected. And, we can age healthily and gracefully, taking care of our bodies and our skin as we go.
FAQs
- How can I increase spermidine levels for better skin?
There are a variety of different options to suit your unique preferences and health goals. If you want to go down the dietary route you could try eating more spermidine-rich foods like soybeans, mushrooms, and wheat germ. If you want higher doses, you might find a supplement fits your needs more effectively. Or, you can try a cream or oil containing spermidine, although these are less well studied.
- How long does it take to see results from spermidine for skin health?
It’s hard to say exactly if and when you might notice any benefits to your skin from using spermidine. Because we are all different, we tend to see results at differing times. Some advocates say they noticed a healthier glow within a few weeks, others didn’t see any noticeable changes for a few months.
- Can spermidine replace my regular skincare products?
The research into spermidine for skincare is still emerging, so we can’t say whether it should replace your existing skincare regime. If you are looking to switch up your skincare, it’s always wise to introduce new products slowly and monitor yourself closely for any changes.
