Reduced L-Glutathione Powder DIY Cosmetic Grade Pure Glutathione Organic Powder for Skin, (0.5 Ounce / 15 gram)

Great product

Very nice product

It will be a while before I can say if this is going to add an extra boost to my skincare products.It arrived promptly and is well sealed in an envelope of foil and a zip closure that is also sealed. The ingredients are clearly listed and there are no additives; just two types of Glutathione.Non GMO and Vegan and no Animal Cruelty. It is marked as USP and Cosmetic Grade.

I add a little to creams and lotions but I'm guessing the ratio. I hope I am using this item appropriately. It calls for a 5-20% recommended dosage. I do not measure but I think I am using the proper amount each time. Additional instructions would be helpful.
