Spearmint, known as Mentha spicata, has been a popular herb for centuries due to its various health benefits. It belongs to the mint family and has a refreshing aroma and cooling taste. Besides its culinary uses, Spearmint is also widely used in traditional medicine to treat various health issues. However, one of the lesser-known benefits of Spearmint is its effect on the skin. This article will discuss the benefits of spearmint on skin and how you can use it specifically for treating acne.
Mechanism Of Spearmint Benefits for Skin
One of the fundamental mechanisms behind the benefits of spearmint on skin lies in its anti-inflammatory, antioxidant, and antibacterial properties. These properties can help reduce inflammation, combat oxidative stress, and fight against harmful bacteria on the skin.

Anti-Inflammatory
Inflammation is the body's natural reaction to injury or infection. Nevertheless, persistent inflammation can give rise to an array of skin issues, including acne, eczema, psoriasis, and rosacea. Spearmint incorporates elements like carvone, limonene, and menthol, all of which possess anti-inflammatory characteristics. These elements can aid in diminishing skin inflammation and easing the symptoms of inflammatory skin conditions.
A study by Xuesheng Han and colleagues provided initial evidence of Spearmint's anti-inflammatory effects on the skin. Its mechanism is based on its ability to inhibit the increased production of pro-inflammatory biomarkers and exert a potent anti-proliferative effect on skin cells. Additionally, Spearmint also significantly impacts tissue regeneration and inflammation [1].
The specific anti-inflammatory mechanism, particularly concerning allergic dermatitis (AD), was confirmed through research in 2021. The study noted that MAEO (Mentha arvensis essential oil) inhibits the production of pro-inflammatory mediators induced by LPS, such as nitric oxide (NO) and prostaglandin E2, as well as pro-inflammatory cytokines. The conclusion was that MAEO has anti-inflammatory and anti-allergic dermatitis effects by inhibiting the ERK/NF-KB signaling pathway [3].
Another review article, which explored the properties of Spearmint, assessed the anti-inflammatory characteristics of Spearmint oil. The study reported that Spearmint oil inhibits the production of pro-inflammatory cytokines from macrophages [2].
Fighting Oxidative Stress
An imbalance between free radicals and antioxidants in the body causes oxidative stress. Free radicals are unstable molecules that can damage cells and lead to premature aging. Antioxidants, on the other hand, neutralize free radicals and prevent them from causing harm.
Spearmint is rich in antioxidants like rosmarinic acid, caffeic acid, and flavonoids that can fight against oxidative stress. These antioxidants can protect the skin from environmental pollutants and UV radiation, major contributors to premature aging.
The review also addressed Spearmint's antioxidant effects through mechanisms that slow down the generation of free radicals and reduce oxidative activity [2].
Spearmint oil contains compounds such as phenolics and flavonoids, which act as sources of hydrogen peroxide and reduce oxidative damage [2]. Its antibacterial properties are also highly beneficial for the skin in preventing bacterial invasion and undesired inflammatory conditions.
Combating Harmful Bacteria
Additionally, Spearmint possesses antibacterial qualities that aid in combating detrimental skin bacteria. This proves especially advantageous for individuals with skin prone to acne, as specific bacterial strains are recognized culprits for triggering breakouts. The constituents within Spearmint, such as menthol and limonene, have exhibited efficacy against bacteria, including Staphylococcus aureus and Escherichia coli.
In addition to these key mechanisms, Spearmint also has a cooling effect on the skin, making it soothing and refreshing when applied topically. It can also help improve blood circulation, which is essential for maintaining healthy skin.
Research on the antibacterial and antioxidant properties of Spearmint concluded that Spearmint oil has good antibacterial activity due to its high carvone concentration, making it suitable for use in the cosmetics and food industries [4].
Studies on the antibacterial properties of Spearmint and clary sage extracts also concurred that carvone is the antibacterial active component of Spearmint [5].
A pharmacological profile review of Spearmint highlighted a range of health benefits, such as liver protection and cancer prevention, and emphasized its anti-inflammatory, antioxidant, and antibacterial properties [6].
Anti-Androgen Properties and Hormonal Balance
Benefits of Spearmint on skin may be due to its anti-androgen properties, which can help address hormonal imbalances. These imbalances often contribute to the development of acne.
In a study conducted on patients with cystic acne, it was observed that many of them had elevated levels of androgens, particularly in women with higher levels of dehydroepiandrosterone sulfate, testosterone, and luteinizing hormone in their serum [7].
Many studies suggest that Spearmint may have anti-androgenic effects. A study involving 12 individuals consuming spearmint-infused herbal tea twice a day for five days showed a notable decrease in free testosterone levels [8].
Additionally, another study conducted over a 30-day period on 42 patients found a significant reduction in free testosterone levels among those consuming spearmint tea [9].
These results indicated a clear impact on reducing androgen levels of Spearmint, thus offering potential benefits for skin conditions caused by hormonal imbalances.
Benefits Of Spearmint on Skin Health
Spearmint For Acne - Prone Skin
One of the key benefits of Spearmint for skin is its ability to help with acne-prone skin. Acne is a common skin condition that can be caused by hormonal imbalances, bacteria, excess oil production, and inflammation. Spearmint contains anti-inflammatory and antibacterial properties that can help combat these underlying causes of acne.
Research has shown that Spearmint can reduce inflammation in the body and also inhibit the growth of certain bacteria that contribute to acne breakouts. This makes it a natural and effective way to help manage acne-prone skin.
Spearmint For Soothing Irritated Skin
In addition to its anti-inflammatory properties, Spearmint also has a cooling effect that can help soothe irritated skin. This makes it particularly beneficial for those with sensitive or reactive skin types.
Spearmint contains menthol, which provides a cooling sensation when applied topically. This can help alleviate discomfort and redness caused by skin irritation or allergic reactions. Spearmint can also be used to calm sunburns, insect bites, and other minor skin irritations.
Spearmint Helps to Hydrate the Skin
Maintaining skin hydration is essential for preserving its overall health and aesthetic appeal. Skin that lacks moisture can present as dry and lackluster, and may even be more susceptible to the development of wrinkles and fine lines. Spearmint is rich in antioxidants, vitamins, and minerals, which play a crucial role in nourishing the skin from the inside.
When used topically, Spearmint can further assist in retaining skin moisture by creating a protective shield against environmental stressors. This property can be particularly advantageous for individuals with dry or aging skin.
Spearmint For Anti-Aging
One of the benefits of Spearmint for skin lies in its anti-aging attributes. As we grow older, our skin naturally experiences a loss of elasticity and firmness, resulting in the development of wrinkles and sagging. Spearmint is rich in antioxidants that can effectively counteract the aging signs by shielding the skin against damage caused by free radicals.
Free radicals are unstable molecules capable of inducing cellular damage and accelerating premature aging. Antioxidants, like the ones present in Spearmint, act to stabilize these harmful molecules and prevent them from harming the skin cells.
Furthermore, Spearmint can also improve skin elasticity, leading to a more youthful and radiant complexion. Its anti-inflammatory properties can also help reduce puffiness and dark circles under the eyes, making it an excellent ingredient for eye creams or serums.
How To Incorporate Spearmint into Your Skincare Routine?
There are several ways to incorporate Spearmint into your skincare routine. One option is spearmint tea, which can benefit your skin health. You can also use spearmint essential oil as a topical treatment by diluting a few drops with a carrier oil and applying it directly to the skin.
Another way to reap the benefits of Spearmint for your skin is by using skincare products that contain spearmint extract or oil. Look for cleansers, toners, moisturizers, and serums that include Spearmint in their ingredient list.
Spearmint Tea - Best Form For Spearmint Skin Benefits
Although Spearmint can be incorporated into your skincare routine through topical application, drinking spearmint tea is considered the most effective form for reaping its skin benefits. Drinking spearmint tea daily can help balance hormones, reduce inflammation and oxidative stress, and improve overall skin health.
Furthermore, drinking spearmint tea is a natural and refreshing way to stay hydrated, which is essential for maintaining healthy skin. You can also add a few drops of Spearmint essential oil to your bath water for added skin benefits and a relaxing experience.
How To Use Spearmint Tea for Acne?
For best results, drinking 1-2 cups of spearmint tea daily is recommended. You can use fresh spearmint leaves or purchase pre-packaged tea bags from your local grocery store. To prepare spearmint tea, simply steep the leaves or tea bag in boiling water for 5-10 minutes before straining and enjoying.
Drinking Spearmint Tea
