Glutathione Serum with 20,000ppm Glutathione, Niacinamide and hyaluronic acid, Dark Spot, Improve skin elasticity, Revitalize complexion, Korean Skincare, 30ml, 1.01 fl. oz.

This is the best product I’ve ever used to exfoliate my skin, to the point of light peeling. I do not have sensitive skin and over the years I’ve tried various at-home peels that promised the elimination of dark spots and red marks from previous breakouts. None of them worked - either they dried out my skin and irritated it without eliminating the discolorations or they were too weak and did nothing at all. This product is not for every day use and I wouldn’t use it all over my face like a serum. However, putting it on problem areas - like my chin, which had discoloration and milia, and some dark spots on my cheeks, has totally eliminated them. I apply a thin layer of this liquid every second or third night. I started using it about three weeks ago, and I noticed improvement within the first week. I know that some reviewers have mentioned an unpleasant smell, but to me, it smells like black licorice.

An on line plastic surgeon recommended this and it did not disappoint. I tried it under my vitamin C and it delivered. After about a week I could see the difference. There is a slight funny smell but it fades immediately. A little goes a long way. It does not irritate my sensitive skin. Helped clear up dark spots. I’ll buy this again since it seems to help keep my face moisturized.

I would’ve liked to give this product five stars because it really does work, especially on evening complexion and softening laugh lines. But it does smell bad. I find that it works best if you do your regular routine and put it on before you moisturize you have to let it dry completely, if you don’t, your moisturizer is going to get mixed with the serum and you’re gonna smell like a rotten egg face. The smell goes away after about 10 to 15 minutesAgain, it works if you can get past the smell.

Since the first drop I used I noticed a very bad smell, when I finished applying this product to my face, my fingers smell so bad, I washed my hands and they still smell bad. I asked my daughter to smell my face and she told me the smell, mom smell so bad. I couldn’t use it for a second time, I could smell all day that bad oil on my face. I returned next day, I couldn’t use it for a second time. It is the first time a product for my face smell bad. I definitely don’t recommend this product.I bought other products from the same brand and they were fabulous.

I had just researched glutathione for skin and have used for a few days. My skin looks tighter and more even already!

This serum I bought in hopes to reduce dark spots hyperpigmentation and fine line and wrinkles in my skin. The packaging was nice and the liquid goes on very lightly just like putting on a lighter weight aloe product. It does have a slight stickiness to it for the first 5 minutes and stink but the stickiness and smell go away. I can’t put my finger on what the smell is but it’s pretty unpleasant in contrast to what some people have said in their reviews. I think it smells like if burning rubber and sulfur mixed, it’s pretty gross. I would consider returning this product just for that if I don’t see much progress or improvement in a few days because it made me kind of queasy. I will try and remember to update this review!

I have used some pretty high end serums and this one was much better, soft, smooth skin, wrinkles demenish. My daughter asked if I had some work done! She said my skin look moisturized, glowing, and I required no make-up, just some SPF, lipstick and mascara. This might just encourage me to get some lash extensions then I will have one less thing to be out the door in minutes!

Does not smell great but the results are most important
