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

I’ve been using the TOSOWOONG Glutathione Serum for a few weeks now, and the results are undeniable. My skin looks noticeably brighter, more even-toned, and has a healthy glow that I didn’t have before. It absorbs quickly and layers perfectly under my moisturizer and sunscreen—no stickiness or residue.What I love most is how gentle yet effective it is. I have sensitive skin, and this serum didn’t cause any irritation or breakouts. It actually helped calm some of my redness and gave my face a more radiant, smooth appearance.The ingredients feel clean and high-quality, and the packaging is sleek and hygienic with the pump dispenser. A little goes a long way, so the bottle lasts longer than I expected.If you’re looking for a serum that delivers on brightening, evens out your complexion, and leaves your skin feeling soft and refreshed, this is it. Highly recommend adding it to your skincare routine!

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.

Seems to be helping my husband's sun-damaged skin. However, be aware that this has a VERY strong, sulfurous smell, a bit like a rotted onion. The smell disappears a minute or so after application, but just know it doesn't smell perfumy like American skin care products.

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

Great

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!

Buen producto elimina gradualmente las manchas y ha hidratado mi piel

Been using for over a month..bottle almost empty. No difference in dark spots, wrinkles or skin at all. Very disappointing
