Many of us who dealt with acne during our teenage years fantasized about the day it would finally disappear as we matured. Unfortunately, for a growing segment of the population, that moment has yet to arrive.
An issue for adults
Roughly 50% of women and 40% of men in their twenties experience acne. These figures decline with age; by the time individuals reach their fifties, the numbers drop to 15% for women and 7% for men.
Although acne is most prevalent among adolescents, especially in males, adult women are more frequently impacted by acne into their later years. For some individuals, this condition persists from their teenage years, while others develop it later in life, typically after the age of 25. Adults often experience a more severe form of acne, characterized by deep, inflamed pimples and subcutaneous nodules or cysts primarily affecting the lower region of the face.
Factors and exacerbators
Acne arises when the body generates an excess of sebum (oil). Normally, dead skin cells dry out and flake off, but when combined with sebum, they can clog pores. Should P. acnes, a type of bacteria found on the skin, enter these clogged pores, it can rapidly multiply, leading to inflammation and causing cysts or nodules to form.
Researchers have pinpointed several elements that can instigate or worsen acne:
- Hormonal fluctuations (44% to 65% of women report outbreaks around their menstrual cycle)
- Medications
- Genetics
- Dietary factors
- Stress levels
- Tobacco use
Diet’s role in acne
While sweet and fatty foods have traditionally been thought to worsen acne, recent studies highlight dairy products, chocolate, and high glycemic index foods as significant contributors to the condition.
Research from 2005 and 2012 established a connection between acne prevalence and milk consumption, especially skim milk. The 2012 study also compared other food categories—such as pasta, bread, meat, cheese, chocolate, fruits, and vegetables—and found little evidence that these influenced acne risk, aside from fish consumption which seemed to offer some protection.
A smaller 2014 study among young men showed a statistically significant relationship between chocolate intake and increased acne severity.
Since 2012, multiple studies have suggested that high glycemic foods, especially refined carbohydrates, are linked to acne, with participants who eliminated these foods showing marked improvement in their skin.
Accordingly, it’s advisable to:
- Identify specific food triggers
- Maintain a food journal to track any changes in breakouts
- Consider removing certain foods from your diet, remembering that dietary adjustments may take up to 12 weeks to show results
The connection between stress and acne
While it’s commonly believed that stress influences acne flare-ups, the precise mechanism remains unclear. One hypothesis is that stress elevates androgen levels (hormones that promote oil production), thereby triggering acne. However, a study conducted in 2007 in young males found that while heightened stress correlated with greater acne severity, it did not necessarily lead to increased sebum production.
Research from 2010 to 2013 has explored the impact of oxidative stress, which occurs when free radicals outstrip the body’s ability to neutralize them. According to studies, oxidative stress alters antioxidant defenses in the skin and throughout the body, aggravating acne. Increased chemical stress markers in the body have been associated with more severe instances of acne.
Some scientists propose a gut-brain-skin axis theory, suggesting that emotional distress can disrupt gut microbiota, enhance gut permeability, and foster systemic inflammation, all of which may trigger acne.
Natural remedies
Despite the myriad of acne treatments available in stores, many are not supported by robust clinical research. Researchers are increasingly focusing on botanical and natural solutions for treating this common skin ailment.
Lavender and bergamot essential oils
Research has confirmed the antimicrobial, anti-inflammatory, and antiseptic qualities of these natural products.
Rosemary
A 2007 in vitro investigation verified rosemary essential oil’s antibacterial effects against P. acnes.
Tea tree oil
A double-blind study from 2007 demonstrated that a topical application of 5% tea tree oil effectively treated mild to moderate acne. A 2010 review indicated that tea tree oil could become a mainstream acne treatment.
Fish oil
A 2012 study found that fish oil supplements could effectively reduce moderate to severe acne cases.
Aloe vera gel
Research conducted in 2014 showed that aloe vera gel enhances the effectiveness of standard topical retinoids for mild to moderate acne.
Green tea extract
A 2009 study found that a lotion containing 2% green tea extract was effective for treating mild to moderate acne, with a 2012 review supporting its potential efficacy.
Zinc
A review from 2013 indicated that both oral and topical zinc could decrease sebum production.
Always consult a knowledgeable healthcare professional before using any of these or additional products.
Supplements for optimal skin health
Researchers are exploring vitamins, minerals, and probiotics for their potential antioxidant and anti-inflammatory benefits to support skin health and combat acne.
Numerous studies underscore the positive effects of oral supplements on skin, leading to increased density, thickness, and elasticity; reduced roughness; fewer wrinkles; and better moisture retention. Promising supplements include:
- Vitamin A
- Vitamin B
- Vitamin C
- Linoleic acid
- Dietary aloe gel
- Probiotics
- Flaxseed and borage oil
Suggestions for vibrant, healthy skin
- Opt for gentle skincare products devoid of fragrances, chemicals, and alcohol.
- Cleanse your face nightly to remove makeup, sunscreen, bacteria, dead skin, and oil buildup that can inflame pores. Rinse thoroughly with warm or cool water and pat dry.
- Avoid harsh scrub pads or astringents that may irritate the skin.
- Select cosmetics and moisturizers marked as noncomedogenic (won’t block pores) and oil-free.
- Stay hydrated to facilitate detox and enhance blood flow, aiding nutrient absorption.
- Drink green tea to reduce inflammation and mitigate DNA damage.
- Consume a variety of fruits, vegetables, lean proteins, and whole grains.
- Engagement in daily exercise facilitates blood circulation and helps cleanse the skin through perspiration.
- Apply a broad-spectrum SPF 30 sunscreen, even on cloudy days.
- Steer clear of smoking.
