Korean Vitamin C Serum with Glutathione – 13% Stabilized Face Serum for Bright, Even Skin – Anti-Aging Ampoule for Dark Spots, Fine Lines & Wrinkles | 10 x 5ml (8 Week Supply)

Absolutely loving this product! It's been about two weeks and I'm already seeing improvements. I use the Serum morning and night after washing my face before using moisturizer or spf. I also like that they come in individual Vials so I can crack open a fresh vial every week.My skin feels noticeably softer and smoother, it’s radiant with reduced pore visibility. Highly recommend!!

Premium Quality ProductIt is an amazing product! Extremely high quality and the price is fair for the type of product they offer. Have been using it daily for 2/3 weeks now (1 vial/week) followed by my moisturizer and I'm seeing great results. My skin feels softer and brighter.

This seems like a nice serum. I've been using it for a week now. I use it once a day at night. I don't know that it's done anything amazing to my skin, but it does feel soft. With any Vitamin C or retinol beauty product, I'm also a bit concerned about the benefits versus the side effects. These types of products may dry out your skin if you use them too often, especially if you have naturally dry or sensitive skin. Fortunately, for me, that has not been an issue with this product.If you do find that this product or a similar Vitamin C or retinol beauty product is drying out your skin, I'd recommend using it less often. Generally, I find every other day or twice a week works well if my skin doesn't react well to the product.This serum has an odd scent. It's kind of a citrusy scent, almost like a sour citrus scent. At first, I didn't like it. I wouldn't say that I love it now, but it's definitely grown on me. The scent goes away quickly once the serum starts to absorb into my skin.These serums come in a pack of 10 small jars of serum. You open the top of the serum jar and then attach the dispenser to the top. Because the jars are glass, you cannot squeeze them. Luckily, it's easy to squeeze the side of the dispenser to get out an appropriate amount of product.The instructions say to use the jar within 7-10 days of opening the jar. If you're using it once a day, that's roughly how long each jar will last. I've used it 7 times now, and there's probably one more application in my first jar. I was very glad to find that these jars last that long. I tried a similar product a while back, and there was only enough product in each jar for maybe 2 applications at best. My guess is that if you use this once a day (probably at night), the 10-jar set should last about 2-3 months. I feel like that's pretty good for the price.

Easy on pulling the cap off- you may open and spill accidentally. But love this product! I’ve added to my skin care and it certainly feels smoother and tighter with this serum. Will buy again.

It's ok ok, the quantity is really less and it's expensive. By the time you start figuring out that's it good or not. It's finish

This is a great Vitamin C product for all skin types. It really helps reduce sunspots and hyperpigmentation while also brightening and softening the skin. It keeps the skin hydrated and protected. Highly recommended!

I love the individually packaged vials! It keeps the serum fresh and potent. I typically finish one ampoule within a week. This formula works wonders for my skin, evening out tone changes and diminishing fine lines. Definitely a must-have product!

I like ampoules because they deliver concentrated doses of skin-enhancing ingredients and always remain fresh due to having a limited amount of product in each vial.I’ve used other ampoules but this is the first Vitamin C one I’ve tried. There are ten vials and each one lasts approximately one week.To open, I first remove the plastic cap and pull up on the metal foil which removes one portion of it and then use a tweezers to remove the rest of the metal foil since it can be sharp. Then I remove the rubber stopper and push the white dispenser cap down over the vial. It forms a good seal with no leaking. To dispense the serum, I either shake it into my hand or squeeze the neck of the cap.The serum is a milky yellow color and has a runny consistency, what I would expect with this kind of product. The scent is not great, citrus combined with something else, but it doesn’t linger on the skin.When I apply to my face, it absorbs pretty quickly so I tend to need more than I would with other serums.Asorbic acid is at the top of the ingredients and so is in a potent concentration. It’s a very unstable form of Vitamin C but this serum has been formulated to be stable plus having 5-7 day doses helps keeps the ingredients fresh and active.I use this as part of my morning routine after cleansing and toning and before my regular moisturizer. It brightens my skin and has improved the tone and texture. I know that continued results will take time due to skin cell turnover.While I am not excited about having to open an ampoule every week, I do like knowing that each time I do, the serum is working like new each time.This would be good for most skin types but folks who are sensitive to added fragrance should use with caution as there are a few ingredients that could cause issues.Highly recommended!
