Here’s all you need to know
What’s in a Whitening Injection?
Whitening injections are made with glutathione, a powerful antioxidant. In the U.S., glutathione is used as a treatment for Parkinson’s disease, while in Korea, it’s often used as a liver detox agent.
But what does it have to do with skin tone?
Our body naturally produces melanin, which is responsible for skin pigmentation. Glutathione helps suppress melanin production and even promotes pheomelanin, a pigment that brightens the skin. Once this was discovered, clinics began offering it as a whitening injection!
What Do Scientific Studies Say?
Research on glutathione’s skin-brightening effects is mixed, but here’s the takeaway:
•
A study on Filipino women aged 30–50 found a decrease in melanin levels after applying glutathione cream.
•
Another study on 60 medical students showed melanin reduction after taking glutathione pills.
Bottom line? Glutathione does have skin-brightening effects, but it’s not 100% medically proven yet.
Who Should Get Whitening Injections?
This treatment is best suited for those with darker or uneven skin tones. If your skin is already fair, you might not see a drastic change.
Are There Any Side Effects?
While generally safe, some studies report potential side effects, such as:
The injection process itself is low risk, but side effects can still occur depending on the individual. If you have any concerns, it’s always best to consult with a doctor before starting treatment!
