Which is better metathione or glutathione? Any recommended brand that is effective and safe to use?
Meta-thione contains Glutathione. Meta-thione is a brand name. Glutathione is an ingredient. Glutathione aids in cellular health, it is not a skin whitening agent. Dark spots are from hyperpigmentation (increased melanin) of the skin whether from scars, age or medication. Hydroquinone is a skin whitening agent which is applied directly onto your skin (a cream), not in pill form. So it’s not in Meta-thione, they brag about that fact. If you are using Meta-thione as a skin whitening agent their own site suggests you’ll get no results if you don’t take a lot of Vit-C. I found nothing off their site that associates any of the ingredients with skin whitening. So I suspect it’s a “claim” and “results are not typical”. If you are taking Glutathione for other reasons, consider buying a generic since you’re paying extra (quite a bit extra) for the brand name “Metathione”.
