Green tea is very high in antioxidants, and drinking it can promote good health.
It may also help reduce acne. This is likely because the polyphenols in green tea help fight bacteria and reduce inflammation, which are two main causes of acne.
There isn’t much research exploring the benefits of drinking green tea when it comes to acne, and more studies are needed.
In one small study with 80 women, participants took 1,500 mg of green tea extract daily for 4 weeks. By the end of the study, women who took the extract had less acne on their noses, chins, and around their mouths.
Research has also found that drinking green tea may lower blood sugar and insulin levels, which are factors that can contribute to the development of acne.
Many studies also indicate that applying green tea directly to the skin may help with acne.
Research shows that the main antioxidant in green tea — epigallocatechin-3-gallate (EGCG) — reduces sebum production, fights inflammation, and inhibits the growth of P. acnes in individuals with acne-prone skin.
Multiple studies have found that applying green tea extract to the skin significantly reduces sebum production and pimples in those with acne.
You can buy creams and lotions that contain green tea, but it’s just as easy to make your own mixture at home.
You can also add the remaining tea leaves to honey and make a mask.
Witch hazel is extracted from the bark and leaves of the North American witch hazel shrub, Hamamelis virginiana. It contains tannins, which have strong antibacterial and anti-inflammatory properties.
That’s why it’s used to treat a broad range of skin conditions, including dandruff, eczema, varicose veins, burns, bruises, insect bites, and acne.
Currently, there appears to be very little research on witch hazel’s ability to treat acne specifically.
In one small study funded by a skin care company, 30 individuals with mild or moderate acne used a three-step facial treatment twice daily for 6 weeks.
Witch hazel was one of the ingredients in the second step of the treatment. Most participants experienced significant improvement in their acne by the end of the study.
Research also suggests that witch hazel may fight bacteria and reduce skin irritation and inflammation, which can contribute to acne.
How to use it
- Combine 1 tablespoon of witch hazel bark and 1 cup of water in a small saucepan.
- Soak the witch hazel for 30 minutes and then bring the mixture to a boil on the stove.
- Reduce to a simmer and cook, covered, for 10 minutes.
- Remove the mixture from the heat and let it sit for an additional 10 minutes.
- Strain and store the liquid in a sealed container.
- Apply to clean skin using a cotton ball 1–2 times per day, or as desired.
It’s important to note that commercially prepared versions may not contain tannins, as they are often lost in the distillation process.
7. Moisturize with aloe vera
Aloe vera is a tropical plant whose leaves produce a clear gel. The gel is often added to lotions, creams, ointments, and soaps.
It’s commonly used to treat abrasions, rashes, burns, and other skin conditions. When applied to the skin, aloe vera gel can help heal wounds, treat burns, and fight inflammation.
Aloe vera contains salicylic acid and sulfur, which are both used extensively in the treatment of acne. Research has found that applying salicylic acid to the skin reduces acne.
Several studies have also indicated that aloe vera gel, when combined with other substances like tretinoin cream or tea tree oil, may improve acne.
While research shows promise, the anti-acne benefits of aloe vera itself require further scientific research.
How to use it
- Scrape the gel from the aloe plant out with a spoon.
- Apply the gel directly to clean skin as a moisturizer.
- Repeat 1–2 times per day, or as desired.
You can also buy aloe vera gel from the store, but make sure that it’s pure aloe without any added ingredients.
8. Take a fish oil supplement
Omega-3 fatty acids are healthy fats that offer a multitude of health benefits.
You must get these fats from your diet, but research shows that most people who eat a standard Western diet don’t get enough of them.
Fish oils contain two main types of omega-3 fatty acids — eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
High levels of EPA and DHA have been shown to decrease inflammatory factors, which may reduce the risk of acne.
In one study, 45 individuals with acne were given omega-3 fatty acid supplements containing both EPA and DHA daily. After 10 weeks, their acne decreased significantly.
There’s no specific recommended daily intake of omega-3 fatty acids. The 2015–2020 Dietary Guidelines for Americans recommends that healthy adults consume around 250 mg of combined EPA and DHA each day.
You can also get omega-3 fatty acids by eating salmon, sardines, anchovies, walnuts, chia seeds, and ground flax seeds.
9. Exfoliate regularly
Exfoliation is the process of removing the top layer of dead skin cells. You can use chemicals to achieve this, or exfoliate mechanically by using a brush or scrub to physically remove the cells.
Exfoliation may improve acne by removing the skin cells that clog pores.
It may also make acne treatments for the skin more effective by allowing them to penetrate deeper, once the topmost layer of skin is removed.
Currently, the research on exfoliation and its ability to treat acne is limited.
Some studies suggest that microdermabrasion, a method of exfoliation, can improve the skin’s appearance, including some cases of acne scarring.
In one small study, 38 patients with acne received eight microdermabrasion treatments at weekly intervals. The participants with acne scars showed some improvements following the treatments.
Another small study found that six weekly microdermabrasion treatments helped stimulate skin repair.
While these results indicate that exfoliation may improve skin health and appearance, more research is needed on acne.
There are a wide variety of exfoliation products available, but you can also make a scrub at home using sugar or salt.
Note that mechanical exfoliation, such as with harsh scrubs or brushes, can be irritating and damage the skin. As such, some dermatologists recommend gentle chemical exfoliation with salicylic- or glycolic-acid-based products.
If you choose to try mechanical exfoliation, be sure to gently rub your skin to avoid damaging it.
How to make a scrub at home
- Mix equal parts sugar (or salt) and coconut oil.
- Gently rub your skin with the mixture and rinse well.
- Exfoliate as often as desired, up to once daily.
10. Follow a low glycemic load diet
The relationship between diet and acne has been debated for years.
Research suggests that dietary factors, such as insulin and glycemic index, may be associated with acne.
A food’s glycemic index (GI) is a measure of how quickly it raises your blood sugar.
Eating high GI foods causes a spike in insulin, which likely increases sebum production. As a result, high GI foods may directly affect the development and severity of acne.
Foods with a high glycemic index include processed foods, such as:
- white bread
- sugary soft drinks
- cakes
- doughnuts
- pastries
- candies
- sugary breakfast cereals
Foods with a low glycemic index include:
- fruits
- vegetables
- legumes
- nuts
- whole or minimally processed grains
In one study, 66 people followed either a normal or low glycemic diet. After 2 weeks, the individuals consuming a low glycemic diet had lower levels of insulin-like growth factor-1 (IGF-1), a hormone involved in acne development.
Another study in 64 people found that those with moderate or severe acne ate diets with more carbohydrates and a higher glycemic load than those without acne.
These small studies suggest that a low glycemic diet may help those with acne-prone skin. Additional larger, longer studies are needed.
11. Cut back on dairy
The relationship between dairy and acne is highly controversial.
Milk and dairy products contain hormones like IGF-1, which is associated with acne. Other hormones in milk may cause hormonal changes and lead to acne.
One study in people ages 10 to 24 found that drinking whole milk three or more days each week was linked to moderate or severe acne. In another study including 114 participants, those with acne were found to drink significantly more milk than people who didn’t have acne.
On the other hand, a study involving over 20,000 adults found no association between milk consumption and acne. Participants self-reported the data in these studies, so more research needs to be done to establish a true causal relationship.
Finally, several research reviews have suggested an association between dairy consumption and acne. The relationship between milk and acne needs further study.
12. Reduce stress
The link between stress and acne is not fully understood. The hormones released during periods of stress may increase sebum production and inflammation, making acne worse.
Stress may also affect gut bacteria and cause inflammation throughout the body, which could be linked to acne.
What’s more, stress can slow wound healing, which may slow the repair of acne lesions. Multiple studies have found an association between stress and acne. However, each of these studies was relatively small, so more research is needed.
One study in 80 participants found no association between stress intensity and acne. However, it noted that acne severity may be related to people’s ability to cope with stress.
Certain relaxation and stress reduction treatments may improve acne, but more research needs to be done.
Ways to reduce stress
- get more sleep
- engage in physical activity
- practice yoga
- meditate
- take deep breaths
13. Exercise regularly
There’s little research on the effects of exercise on acne. Still, exercise affects bodily functions in ways that may help improve acne.
For example, exercise promotes healthy blood circulation. The increase in blood flow helps nourish the skin cells, which may help prevent and heal acne.
Exercise also plays a role in hormone levels and regulation.
Several studies have suggested that exercise can decrease stress and anxiety, both of which can contribute to the development of acne.
The U.S. Department of Health and Human Services recommends that adults get 150 minutes of aerobic exercise and engage in strength training activities two days per week.
This can include walking, hiking, running, and lifting weights.
