Green tea has been found to have potential benefits when used in nail care. It is rich in antioxidants, which can help to strengthen and protect the nails from damage. Green tea may also have anti-inflammatory properties that can help to reduce swelling and redness around the nails. Some nail products, such as nail strengtheners and cuticle creams, may contain green tea extract as an active ingredient. Additionally, soaking the nails in green tea can be a relaxing and nourishing treatment for the hands and nails.
