Green tea has a wide range of therapeutic properties that can benefit your skin in a variety of ways. Some of the most important benefits include the following.
1. Protects against skin cancer
Green tea contains polyphenols and six different types of catechins, with epigallocatechin gallate (EGCG) and epicatechin gallate (ECG) having the most potency. These compounds have antioxidant properties.
Antioxidants are molecules that have the ability to fight free radicals in the body. Free radicals are compounds that can harm your body, your health, and your skin if their levels get too high. They can cause cellular damage, and have been linked to many diseases, including cancer.
According to a 2010 studyTrusted Source, the antioxidant power of EGCG can help repair DNA damage caused by ultraviolet (UV) rays from the sun. This, in turn, can help protect you from nonmelanoma skin cancer.
2. Fights premature aging
A 2003 study showed that the antioxidant EGCG, which is abundant in green tea, has the ability to rejuvenate dying skin cells. By protecting and repairing your cells, this antioxidant can combat signs of aging and make dull skin look healthier.
The vitamins in green tea, especially vitamin B-2, can also keep your skin looking more youthful. Vitamin B-2 has the ability to maintain collagen levels, which can improve the firmness of your skin.
3. Reduces redness and irritation
Green tea also has anti-inflammatory propertiesTrusted Source. This is due to the tea’s high content of polyphenols.
Green tea’s anti-inflammatory properties can help reduce skin irritation, skin redness, and swelling. Applying green tea to your skin can soothe minor cuts and sunburn, too.
Due to its anti-inflammatory properties, studiesTrusted Source have also found topical green tea to be an effective remedy for many dermatological conditions. It can soothe irritation and itching caused by psoriasis, dermatitis, and rosacea, and it may also be helpful for treating keloids.
4. Treats acne
The antioxidant, anti-inflammatory, and antimicrobial properties in green tea may make it an effective treatment for acne and oily skin.
According to researchTrusted Source, the polyphenols in green tea, when applied to the skin, help reduce sebum secretion, which can lead to acne.
The polyphenols in green tea also have the ability to fight against infection by damaging bacterial membranesTrusted Source. This means that green tea can be a useful tool for controlling bacterial growth that can cause acne.
5. Moisturizes skin
Green tea contains several vitamins, including vitamin E, which is known for its ability to nourish and hydrate the skin.
In one studyTrusted Source, participants applied an experimental formulation of green tea extract to their forearm for 15 and 30 days. At the end of the study, the researchers found that the participants had increased skin moisture and a reduction in skin roughness.
