5% L-Glutathione (88B/mL) Flexible Liposome Face Serum - High Concentration with Vitamin B3, Vitamin E, Tranexamic Acid for Hydrating & Brightening (1.01 fl oz / 30ml)

So far so good. I'll know after a couple months of use, but so far it's a very nice lightweight serum with proven ingredients. Took me a minute to figure out how to open the bottle, but once you remove the metal cap and rubber stopper, then you put on a nice squeeze tip. The tip makes it easy to dispense without waste. Watery texture. Smells a little unpleasant, but that's okay for 5% glutathione. Kind of like how some Vit C serums smell like hot dog water. Works in tandem with Vit C and I'm hoping for some great brightening after a couple of months. Be patient when starting new skincare products. It can take WEEKS (6-8) to see results. Add one product at a time and give it time to see if it's working.

Very pleased - life saver and confidence booster . I have a health condition that makes my skin very dry , dull and even grayish dirty look when it flares or I eat sugary foods . On my worst weeks I use this and it really brightens my skin almost immediately . I pair it with vitamin c, e ferulic for a Synergy effect . Almost immediately I go from a 3-7 on the looks scale I kid you not . Next few days I don’t need much makeup either . Recently I’ve been pairing it with cortex peptide booster and I’m obsessed . Of course make sure you use moisturizer on top and sunscreen :) wishing everyone healthy glowing skin !!!

The smell is horrible! It smells like rubber tires.

I’ve been using this serum and I absolutely love it!The 5% Glutathione, Vitamin B3, and Vitamin E really made my skin brighter and healthier.It also helped fade some dark spots thanks to the Tranexamic Acid.The lightweight texture feels so comfortable and absorbs quickly.My skin feels more hydrated and glowy every day — I highly recommend it!

I’ve been using this serum, and I’m already impressed with how my skin is looking. It feels much smoother, and I’ve noticed a slight improvement in my overall skin tone. The glutathione, niacinamide, and tranexamic acid blend seems to be working well on some of my uneven spots, and my skin definitely looks a little brighter.I like that it has no added fragrance — the natural scent of glutathione is a bit sulfuric, but it’s not overpowering and doesn’t bother me. The texture is super light, absorbs quickly, and doesn’t leave any sticky residue, which is great for layering with other products or wearing under makeup.My skin is usually pretty sensitive, and I’ve had no irritation so far. I’m looking forward to seeing how it works long-term, but for now, I’m happy with how it’s been making my skin look fresher and more radiant.

K-Beauty really never disappoints. It's lightweight, and it's brightening!

This serum is one of the most talked-about skincare products in Korea right now. Among all the antioxidants, glutathione is the one everyone’s reaching for lately, and this formula shows why.Just a few days into using it, I could already see my skin looking brighter and more even. The texture is lightweight, absorbs well, and layers nicely under other products.The only downside is the smell—it’s quite noticeable and has a bit of a sulfur-like scent. But it fades after a few minutes, and the results make it totally worth it.

It is around time to apply vitamins on my skin before the summer. My skin is pretty bright so that I can get dark spot really easily. I need something concentrated so that I don’t need to put a lot! My skin is pretty sensitive but this one I don’t have any redness or itching. I think this would be a great gift due to packaging and design!
