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.

Buen producto elimina gradualmente las manchas y ha hidratado mi piel

I usually do my own research beige using skin care products but this time I blindly ordered this product due to the highly marketing glutathione is getting lately, well I have to accept that this time i failed, I had one of the most horrible side effects I ever experienced, my skin was so irritated and over dry that I had no choice but to see a dermatologist, she told me that the concentration of 20,000 ppm of glutathione of this serum it’s far to high even for the experts to use without the side effects, she told me she don’t understand why is being sold like candies ! and the damage to my skin will take few weeks to heal my skin feels and looks like a cardboard and used it only twice so please be cautious maybe it was to much for me maybe it will work for you but test it before you apply it to your face its not worth it trust me i totally regret using this serum

I really like how this product helps reduce some of my dark spot/acne scars. But the smell! I want to throw up every time I open it. Not a pleasant smell I’m telling you if you are someone who have sensitive nose.

I didn't think the smell was that bad, it seems to work

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!

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.
