What is the best to remove dark patches in my face? Can I have glutathione injections for melasma? (Photo)

Hi Shawie, we use up to Hydroquinone 8% for our Melasma cases.  To see examples for our Los Angeles patients, click on the before and after photos at the link below.  

Thank you for your question.  Skin discoloration is a very prevalent problem in women over the age of twenty.  It is also increasingly common in men with increased sun exposure.  
Risk factors include thyroid disease, sun exposure, hormones, pregnancy, family history, PIH, and birth control. Melarase AM and Melarase PM have been extremely effective in reducing pigmentation associated with skin discoloration and hyperstimulation of melanocytes. 
In my practice, patients with hyperpigmentation benefit from twice daily application of the creams. Melarase AM in the morning, followed by Melarase PM in the evening. Melarase AM contains four active sunblocks, so sunscreen is not needed unless your sun exposure is very high or you had a recent procedure/laser. SPF of 30. Melarase PM contains active skin lighteners to even out skin pigmentation. If you are concerned about the development of pigmentation, contact our office to discuss details and to obtain a regimen for Melarase. 
Recommendations:  5-step Daily Brightening Kit has everything you need to improve dark spots, skin discoloration, melasma, and hyperpigmentation caused by sun exposure, hormones, scarring, and the environment. It’s a powerful daily brightening kit that can help bring out your skin’s natural, healthy glow. Ideal for use on the face, neck, and hands. 
Includes: Melaclenz, Melapads, Melarase AM, Melarase PM, Elevase, and Spectrase

There is no "cure" for melasma but there are great treatments. We are doing a clinical trial now on clear + brilliant with bleaching and microneedling and getting amazing results. I suggest you see an expert. You will need lifelong treatment, sun protection, skin care. But these treatments can give you improvement and then you maintain. Best , Dr. Emer.
