The animated film "Nezha: The Demons of the Sea" has risen to the top of the global box office, and the iconic dark circles under Nezha's eyes are also impressive. In daily life, many people are also troubled by dark circles under their eyes, as if wearing two "smoky eye makeup" that cannot be removed no matter what. Don't worry, plastic surgeons will introduce the method of "removing" dark circles through injection to help you get rid of this trouble. Dark circles are mainly divided into vascular type, pigmented type, structural type, and mixed type. Mixed type refers to the occurrence of a mixture of several situations. Injection therapy has different mechanisms of action for different types of dark circles. Vascular dark circles are caused by thin skin around the eyes, obvious subcutaneous blood vessels, and blood stasis, making the eye area appear dark and blue. For vascular dark circles, the common injection material is hyaluronic acid. It is like a "hydrating expert" that can increase the thickness of the skin around the eyes, cover obvious blood vessels, make the skin around the eyes fuller and smoother, thereby reducing the color of dark circles. Moreover, hyaluronic acid is a substance that is already present in the human body, with high safety and minimal occurrence of rejection reactions. The formation of pigmented dark circles is caused by long-term sun exposure, pigmentation after inflammation, etc., which leads to the accumulation of pigmentation in the skin around the eyes. For pigmented dark circles, in addition to hyaluronic acid, some products containing whitening ingredients such as vitamin C and glutathione can also be injected. These ingredients can inhibit the production of melanin, promote the breakdown and metabolism of melanin, just like a deep "whitening care" for the skin around the eyes, gradually fading pigmentation and making dark circles disappear slowly. Structural dark circles are often caused by structural issues around the eyes, such as protruding eye bags and sunken tear troughs that create shadows, visually exacerbating the dark circles. For structural dark circles, it is mainly improved through filling. For example, filling the tear groove with hyaluronic acid or autologous fat can make the depressed area flat and reduce the production of shadows. Autologous fat is taken from oneself, and after filling, the effect is natural and can be maintained for a long time. Moreover, hyaluronic acid is relatively easy to operate and recovers quickly. However, injection therapy for dark circles is not suitable for everyone. If you are in your menstrual period, pregnancy, or lactation period and your hormone levels are unstable, injections may have adverse effects on your body, so it is important to avoid these periods. In addition, injection therapy is not recommended for people with inflammation or infection of the skin around the eyes, or those with scar constitution or allergies to injection materials. Before deciding to undergo injection therapy, it is important to seek a professional doctor for a face-to-face consultation. The doctor will assess your specific situation to determine if you are suitable and choose the most suitable treatment plan for you. (New Society)
