TOSOWOONG 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 am taking Glutathione as a oral supplement with amazing benefits, especially in your skin, the glutathione makes it look glowing, clear, lighter without blemishes, moisture with s beautiful smooth texture. So I thought it would be a great addition to my glass skin routine for my face and neck, and it was the best idea ever since it created a perfect balance in my very oily combined skin. My usual problem is if I apply a good moisturizer the T zone got very oily and I start experiencing breakouts but that it is better than wrinkles...well since I added the glutathione serum the oily skin patches went away, I noticed that my skin is able to be moistened in those areas that are needed the most and the oily area stays under control. It is amazing, just a warning, it stinks a lot when applied but it fades away, the smell is totally normal since the glutathione is a potent antioxidant so it will smell like a very strong vitamin supplement or something similar I really don't know how to describe it, but it is fine, not a bad product related smell. It can dry out your skin easily so PLEASE use a good toner (The 6 Peptide Skin Booster), Azelaic Acid 14%, Glutathione after and then a really good moisturizer like La Roche-Posay Lipikar AP+m Triple Repair Moisturizing Cream with your favorite SPF 50 and any other day I alternate the glutathione with Tretinoin Cream 0.1% I guarantee you the results are out of this world!

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 why 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 be 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 leaves a soft glow and layers well with my other skincare as long as I use them 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 almost 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.

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.

I really like this product. Lightweight and easy to use. Smells is a little funny but it disappears instantly. I have not had issues with irritation. Many people had commented on how my skin looks so "fresh"

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

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 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.

J’ai découvert ce produit et, vu les commentaires négatifs sur son odeur, j’ai failli renoncer à l’acheter. Et bien, heureusement que j’ai suivi mon instinct, et que j’ai passé commande : le produit est super efficace. L’odeur n’est pas agréable du tout mais, je m’attendais à pire. Pour l’efficacité, cela vaut le coup de supporter l’odeur.

Siero fantastico, l'ho appena ricomprato per la seconda volta perché ha migliorato la grana della mia pelle in modo fantastico, ora è molto più liscia e luminosa! Ho la pelle molto sensibile e che diventa acneica appena faccio il minimo errore, e questo siero non mi ha causato nessuna reazione spiacevole, anzi! L'odore in effetti non è il massimo, ma è indice della presenza di un'ottima qualità e quantità di glutathione, quindi va benissimo!

Very good

Didn’t like the funny smell

Smells not good but works good i recommend it
