IOPE Gluta Vitamin C Brightening Serum | 25% Pure Vitamin-C and 1,000ppm Glutathione, Anti-Aging and Anti-Oxidant, Reduces Dark Spots, Korean Skincare, 0.78oz.

My review is for the IOPE Gluta Vitamin C Brightening Serum - 25% Pure Vitamin-C and 1,000ppm Glutathione, Anti-Aging and Anti-Oxidant, Reduces Dark Spots, Korean Skincare, 0.78oz.The price is well over $70 an ounce (this container ~ 3/4 of a single ounce FYI!). The color is a bit alarming, but it goes on well and no gumminess it you use with other products.I have quite sensitive skin, and so I'm generally cautious when trying new products like this (though not severe enough that I first patch test). I'm happy to report that I did not experience any redness or irritation during or after using this.Note that this kind of product likely to cause sensitivity / skin irritation with its primary ingredient of Vitamin C...but I was pleased I could use with NO problem!Bottom line: I would consider purchasing again. One can never know if its truly efficacious against dark spots since no real resting and I can't do a 1:to:1 test myself, but I think continued use may elicit lasting results!

The vitamin c comes in an amber glass bottle sealed tight and the dropper is packaged separately in the box. As warned on the packaging, when you open the bottle, there is a release of gas. The serum does not smell the best, but I’ve experienced worse.So far it's been good, I haven't experienced any allergic reaction to the serum. It is a little sticky, but dries fairly quickly.

I was excited to try this serum because the 25% pure vitamin C combined with glutathione figures to help brighten my skin, and indeed, I’ve noticed a difference in my dark spots after consistent use, so far after a few uses it has been very effective! The texture absorbs well without feeling sticky...but I do find that I like to follow up the application of this product with a moisturizer. Overall, this is a very powerful but gentile serum, and that's exactly what I was hoping for. The value is there for sure with this one.

The Glutathione and Vitamin C combination has the potential of lightening dark spots and improve the appearance of my face. I’m using it as part of my daily routine before applying moisturizer and BB foundation for a natural look. The scent is similar to an oral vitamin C and texture is not sticky and light weight.

I returned this product twice because both bottles was nearly empty.

No visible change after 3mo of consistent use. Not sure if the product was no longer effective when arrived as it released a lot of air as I opened the bigotte as if it was fermented. Texture: sticky.

I'm in my late 50s and trying to erase the mistakes of my youth. I have some darker areas on my face and thought this would help. Upon opening you hear a fizz sound reminds me of when you open a soda. Since I do have sensitive skin I started using this every two days. I use in the morning after I wake up and wash my face. It goes on easily and I have not had any negative reactions. I I'm going to start using every other day and then we'll increase to every day. I think some of my hyperpigmentation has faded in the 2 weeks that I've used this (5 applications). Once I step up using more often I will update this review if I've noticed any changes.I hope this review has been helpful.

I've been using the IOPE Gluta Vitamin C Brightening Serum for a few weeks, and it's made a noticeable difference in my skin. My fine lines have softened, and my complexion looks brighter. A little goes a long way, and it absorbs quickly without feeling sticky. I also store it in the fridge to extend its shelf life, which helps slow oxidation.The only downside is the scent—it has a strange fermented citrus smell that fades after application. Despite that, it works well, layers smoothly under moisturizer and sunscreen, and hasn’t caused any irritation. Overall, a great option for brightening and anti-aging.
