Arnica’s Skin Benefits: Natural Pain Relief?

6 Mins read

Arnica montana, often simply known as Arnica, is a perennial herb. This means it does not have to be replanted each year. The herb is native to Europe and North America, and sometimes you will also see it referred to as wolf’s bane. This yellow-orange flower has been used for centuries in traditional medicine, particularly for its powerful anti-inflammatory and analgesic (pain relieving) properties. In recent years, Arnica has gained popularity in the skincare world, where it is celebrated for its ability to soothe irritated skin and help heal the skin. But what does the science say about Arnica’s skin benefits? Let’s dive into the evidence and uncover if arnica’s skin benefits are marketing hype or truly helpful.

The Active Compounds in Arnica

The biggest marketing claim of arnica’s skin benefits is its ability to relieve pain. These pain-relieving properties are associated with the rich composition of bioactive compounds. In some fundamental in vitro experiments, some common compounds showed benefits that were attractive to skincare applications. These include:

Sesquiterpene Lactones: The highest concentration compound in Arnica, sesquiterpene lactones, has anti-inflammatory effects. These compounds stop certain immune cells from activating, which is important because the activation of these immune cells is responsible for painful swelling that can occur in the skin after treatments or an injury.

Flavonoids: These plant-based antioxidants protect the skin from oxidative stress by neutralizing free radicals. This helps reduce skin aging and promote overall skin health.

    Polysaccharides: Like most natural materials, Arnica has natural sugars. These sugars are humectants that hold onto water, similar to hyaluronic acid and other botanical ingredients used in skincare. This is important in skincare because it can help maintain the skin’s moisture balance.

      So, although on their own in vitro testing (cells in a petri dish), these compounds have shown promise, let’s talk about their skin benefits when extracted from the Arnica and used in skincare products.

      So What Does The Science Say About Arnica’s Skin Benefits

      Several studies have used arnica gels after an in-office procedure. Some studies looked at the benefits of Arnica when taken orally. However, when I was looking at the benefits of arnica for skin, I only read studies that used it in topical (applied directly to your face in a gel or cream) applications.

      Most studies examined the gel in concentrations of 10 or 20%. The results of the studies that examined 10% gels did not show a noticeable reduction in pain after in-office procedures. However, there were promising results for the gels with a 20% arnica extract concentration.

      One study showed it could reduce puffiness and bruising around the eyes after nose surgery. Other studies showed it worked better than some creams at reducing bruises from lasers or after facials. A study evaluated its effects after facelifts; however, there was not a perceivable difference in the pain, bruising, or swelling with or without the arnica gel.

      It’s important to note that arnica’s skin benefits were most effective as a supplement to other pain-relieving treatments. Today, it cannot be definitively said if arnica is an effective standalone pain-relieving ingredient; more research is needed. Still, there is some preliminary evidence that arnica shows promise as a natural pain-relieving supplement aid after surgery or injury.

      How to Incorporate Arnica into Your Skincare Routine

      Although the science does not resoundingly say, Arnica can replace more traditional pain relieving medication. For the right skincare concerns, there could be a potential use. Before you incorporate arnica into your skincare routine, consult a dermatologist or skincare professional to ensure it will address your skin concerns and needs. However, as a general guideline, when the pain is less severe, like mild sunburns or a sensitized barrier, this may be an opportunity to incorporate Arnica into your skincare routine. Here are some practical ways to use Arnica in your skincare routine:

      Arnica Creams and Gels: These are the most common forms of Arnica used for skincare. They can be applied directly to the affected area to relieve mild pain. When choosing an Arnica cream or gel, look for products with an arnica concentration of 20%, and that contains a standardized extract to ensure consistency in potency. Additionally, products with their own clinical testing are typically more reliable (assuming the testing was done with a reputable lab) than those without.

      Arnica Oils: Arnica oil can be used for massage, especially after intense physical activities. It can help relax sore muscles and reduce inflammation. However, Arnica oil should always be diluted with a carrier oil, such as jojoba or almond oil, before application to avoid skin irritation. Again, this can help with mild pain relief, and you want an oil that has 20% arnica extract.

      Arnica in Combination Products: Many skincare products combine Arnica with other soothing ingredients like aloe vera or chamomile. These products can be particularly beneficial for people with sensitive or irritated skin, providing a synergistic effect that enhances the overall soothing properties. Look for products that have clinical testing when you can because the formulation can make or break the ingredient’s effectiveness.

        Potential Watch Outs for Arnica in Your Skincare Routine

        Despite its many benefits, it’s essential to use Arnica with caution. Here are some considerations to keep in mind:

        Skin Irritation: Arnica is a potent herb, and you do not want to fall victim to the trap of higher concentration = more effective. In high concentrations, it can cause skin irritation, especially in those with sensitive skin. It is always advisable to do a patch test before applying Arnica to a larger skin area. 

        Avoid Open Wounds: Arnica should not be applied to broken skin or open wounds, as it can cause irritation and potentially delay healing.

        Allergic Reactions: Some people may be allergic to Arnica, particularly those allergic to Asteraceae plants, such as daisies and marigolds. If you experience any signs of an allergic reaction, such as itching, redness, or swelling, discontinue use immediately.

        Oral Use: While Arnica is commonly used in homeopathy, it should never be ingested in its pure form as it is toxic and can cause serious side effects, including nausea, dizziness, and organ damage.

          Conclusion: Is Arnica Right for Your Skin?

          Arnica’s primary benefit for the skin is its pain-relieving properties. Like most botanical ingredients, it also has antioxidant and hydrating properties; however, the pain-relieving benefits make it stand apart from other botanical skincare ingredients. There is some early evidence that arnica has pain-relieving benefits when used in skincare, especially for those prone to minor skin traumas or post-surgical recovery.

          However, it is essential to use Arnica properly and be aware of its potential side effects. Always opt for high-quality, diluted products and consult a healthcare provider if you’re unsure about its use.

          In conclusion, Arnica is not a one-size-fits-all solution, but it can be a powerful ally in your skincare arsenal when used correctly. Whether recovering from a minor injury, dealing with post-surgical bruising, or simply looking for a natural way to soothe inflamed skin, the science behind Arnica’s skin benefits indicates it has a place in your routine. By understanding its benefits and limitations, you can harness the healing power of nature to keep your skin looking and feeling its best.
