Whitening injections—though the name sounds uplifting—are often misunderstood by many. So let's dive into what they really are!
First, why does skin darken?
Your skin tone is determined by melanin levels.Higher levels result in a darker, yellowish complexion, while lower levels yield fairer skin. Melanin production depends on the activity of tyrosinase within melanocytes. This enzyme's activity is primarily influenced by genetic factors and environmental triggers (e.g., UV exposure activates tyrosinase).
SO! What exactly is a whitening injection?
The story of whitening injections actually began with vitamin C injections. Vitamin C inhibits tyrosinase activity, reducing melanin production and resulting in fairer skin.
Today's whitening injections feature improved formulas with added ingredients like glutathione and tranexamic acid, enhancing their efficacy.Glutathione detoxifies the body, improving dull complexions and reducing pigmentation concerns; tranexamic acid diminishes accumulated melanin for a brighter, more even skin tone. Are whitening injections safe? While whitening injections deliver rapid results, safety remains a valid concern. Currently, China neither approves nor prohibits their use, leaving them in a regulatory gray area.Exercise extreme caution before undergoing whitening injections.
Some individuals experience temporary nausea, lowered blood pressure, or dizziness post-injection, typically resolving within 20 minutes of rest. However, some plastic surgeons claim excessive use may increase risks of uterine and breast cancer. Yet others argue this assertion is premature, requiring long-term follow-up studies for conclusive evidence.
It's important to note that whitening injections are not suitable for everyone. They may be appropriate for individuals with facial pigmentation, overall dark complexion, sun-damaged skin requiring repair, or poor skin tone due to irregular lifestyles, excessive alcohol consumption, or impaired liver function. Additionally, some may use them for post-surgical or post-phototherapy skin maintenance.
The following groups should avoid whitening injections:
1. Pregnant women and women during menstruation.
2. Patients with cardiovascular disease or diabetes.
3. Individuals with other severe illnesses, particularly those with pigmentation issues caused by endocrine disorders, as the treatment is less effective in such cases.
