Finger joint wrinkles can be lightened through daily care, medication and medical treatment. 1. Daily care: Paying attention to the protection of hand skin, such as wearing gloves when working, applying hand cream after washing hands, applying sunscreen when going out, etc., can help improve the symptoms of deep finger joint wrinkles. Eat more fresh fruits and vegetables to replenish vitamins, which will help to restore the healthy state of the skin. 2. Medication: For patients with serious knuckle wrinkles, you can use vitamin E cream, urea cream and other medications to apply locally to achieve the purpose of moisturizing and hydrating and fading the wrinkles. 3. Medical treatment: when the knuckle wrinkles are obvious and consciously affect the aesthetic appearance, you can also consider medical treatment, such as subcutaneous injection of hyaluronic acid, which can help to improve the symptoms of deeper wrinkles. It is recommended that patients who do not have obvious effect after general care or have serious symptoms should go to regular hospitals, choose the best treatment plan under the guidance of doctors, and avoid using medication privately.
