"Got during prime day for a great price! Just started using but has a good consistency, not sticky at all, absorbs quickly. No immediate irritation, No scent I can detect thank god, I don’t do fragrance on my face. Will try to update after a month of consistent use, just started using a few days ago."
"I not only use Glutathione 7 Dark Spot Serum on my face but on my hand that has an ugly dark spot I want to get rid of. In less then a month I'm seeing great results on my hand and taking photos and documenting the results. Its the only thing I've used where I actually see a difference so I bought 2 more bottles."
"I’ve been really impressed with the ma:nyo Glutathione 7 Dark Spot Serum. It has a lightweight, fast-absorbing texture that feels comfortable on the skin without being sticky or greasy. After using it consistently, my skin looks brighter, more even, and post-acne marks have gradually started to fade. It layers well with the rest of my skincare routine and hasn’t caused any irritation. If you’re looking for a gentle serum to help improve skin tone and dark spots, I definitely recommend giving this one a try!"
"I love Manyo products, and this serum has become a must-have in my nighttime routine. The formula includes several ingredients I look for when targeting uneven tone, including tranexamic acid, alpha arbutin, glutathione, and kojic acid. It also has plenty of soothing and hydrating support from panthenol, allantoin, polyglutamic acid, glycerin, squalane, and centella asiatica. The serum has a creamy, medium-weight texture that absorbs beautifully and feels very soothing on my mature combination skin. I also appreciate that there is no added fragrance. After about three months of consistent use, I have noticed a real improvement in the brightness and evenness of my skin tone. My skin simply looks clearer and more luminous. This is one I plan to keep repurchasing."
"Been using for 2 weeks & my dark spots have definitely gotten lighter. Doesn’t make my face feel sticky or weird. I apply the serum then the patches & leave them on until they’re translucent."
"I love this product it’s my second bottle. I can see a change on on my face brighter and the spots are getting lighter."
"Effectiveness: I started using this as soon as I received it religiously, I can see a huge difference in before and after. The dark spots are fading drastically and they have been there for years."
"This is my second time buying this item I guess I wasn’t so lucky this time around the delivery company Veho left my package in the hallway near the mailboxes and someone stole it. On the app you can leave delivery directions I guess they were too lazy to read it or could not read! But I never received the package!"
"Excellent product with non harmful products and very good quality products. Fast delivery and awesome price. I requested another one before it goes out of stock."
"Love this Serum and it’s really helped with my dark spots and same with the dark spot patches I 100% recommend especially after struggling with dark spots so long it really helped"
