Glutathione 2% Serum, Dark Spots & Elasticity, Radiant Complexion | 2% (20,000ppm) Glutathione, Niacinamide, Hyaluronic Acid for Dark Spots & Skin Elasticity, Glow, Korean Skincare, 2.02 fl oz

This is a great glutathione serum. I had a lot of dark spots and texture on my face from my first failed attempt at using tretinoin. The tretinoin burned my face because I jumped right in with the highest concentration and used it every night without getting used to it properly. That was a big mistake. I looked for a few products to help heal my barrier and remove the now glaringly unsightly spots from my skin. I picked up this serum about a month and a half ago, along with some other great products. I chose Tosowoong’s alpha arbutrin cream, a different brand’s thick barrier cream, and a couple different sheet and gel masks. I applied my tretinoin much more carefully and slowly until I was able to tolerate it and not burn. It’s made a difference. Most importantly during the healing process the Tosowoong glutathione serum has been so effective at soothing and moisturizing my skin while also delivering a gentle peeling effect to remove the discoloration and damaged skin. I don’t know people make such a big deal about the product scent, it’s slightly stinky for a few seconds then it dissipates. It’s got transparent and effective ingredients and plenty of emollient additives. I find the product texture to neither thin nor thick, and only the tiniest bit sticky. It’s is easy to smooth over the skin and caused my already irritated skin no woe. I smooth it all over my face, chin, neck, and then gently pat it in. It leave a soft glow and layers well with my other skincare as long as I use the then in the right order. I use three little drops and it goes a long way. I am still less than halfway through my first bottle. At this point, having this serum in my skincare routine is a must. My face is glowing at 50 years old and I love the results. I will be purchasing another bottle once I run out. I feel like the price is fair for the effectiveness. Hope you find this useful.

I’ve been using this serum consistently and really like how it feels on my skin. The texture is lightweight, absorbs quickly, and doesn’t feel sticky. The smell is strong (as it should be because it’s real glutathione) but after a few minutes it’s gone. After regular use, my skin looks brighter and more even-toned. It layers well under moisturizer and makeup. Definitely a nice addition to a skincare routine.

Yes, it smells like sulfur, because glutathione contains hydrogen sulfide in its reduced state. Mix just 2-3 drops at most into your moisturizer in my palm before applying. The smell fades pretty quickly, just don't get it on your shirt. It absorbs quickly and is not sticky. The serum seems to be helping with the skin texture under my eyes, but it is too soon to tell if the age spot on my cheek has faded. Will update after more time consistently using this.

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.

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.

This Duo pack is like Christmas.. Pure product so necessary for your skin. First line of defense . I have for years used a Glut. Serum from a company in Canada that has the owner & Chemist herself. Saying a Glut Serum is her “Desert Island & only had that/her serum as her GO TOO product .. they & others sell for 3X the price so finding this PURE Glut at this price I Doubled & LOVE this .. This is a true statement .. Let it sit To dry, or use your Blow Dryer on cool to dry.. The product is PURE Ladies ..

Ive been using it for a few weeks and I honestly do not see any brightening of my skin. Also, it has a slight funky smell. It fades after a few minutes, but while applying - yuck!

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!
