Gentle serum with nice ingredients
This serum is a milky white color that is a mediun texture (not watery, and not super thick) and spreads well and easily. It absorbs pretty quickly, and doesn't leave me too sticky after, nor has it caused any irritation in over a week of daily use. I also haven't noticed any difference yet in terms of brightening or wrinkle reduction, but 1) know that this can take up to 12 weeks with astaxanthin, and 2) already use niacinamide and vitamin c and have probably already seen as much progress as I can expect in the way of evening out skintone and reducing the appearance of freckles.
In English, it says there are only 6 ingredients, but given the avaialable concentrations on the box (4.3% niacinamide, 0.01% astaxanthin) that doesn't make sense. The full ingredients list is only in Korean, but after using an online image translator can see that both lists include great ingredients that have all proven to be quite effective and are gentle for sensitive skin. I also really appreciate that it has the percent niacinamide on the box because this is a staple ingredient for me and so many products have it that it's nice to be able to know how much I'm using when I combine differemt serums and moisturizers that include it so that I'm in the zone that's best for my skin and not using too much.

lightweight, did not irritate my skin
I have been using this ampoule for about 3 weeks now and I like how it makes my skin feel. It doesn't feel harsh, my skin didn't seem to mind it because it didn't look or feel irritated after the 3 weeks of use. I am not solely using this product as my night time moisturizer but it is an addition to my other moisturizer. It is easy to apply, doesn't feel heavy, sticky, or tacky. I can't say how this works for existing blemishes and imperfections because I am mainly using this as a prevention. I recently had some of my sun spots laser-ed so I am trying to keep any additional sun spots from appearing again, which is why it is so important for me to keep up with the prevention routine. This product is excellent for that. I did take a look at the ingredients list and while I'm fine with most of it, I did notice there is a silicone in this. I try to avoid silicones but I'm not going to say it is a dealbreaker. All in all I like this product and will keep using this until I'm done with the entire bottle.
I didn't see the ingredients list posted on this page yet so here it is, in case you need to see what's in this serum before making the decision to purchase.
Ingredients:
Water, Butylene Glycol, Phenyl Trimethicone, Niacinamide, Tranexamic Acid, 1,2-Hexanediol, Caprylic/Capric Triglyceride, Polyglyceryl-6 Dicaprate, Arginine, Carbomer, Ethylhexylglycerin, Adenosine, Astaxanthin(100000ppb), Melia Azadirachta Flower Extract, Melia Azadirachta Leaf Extract, Betaine, Ocimum Sanctum Leaf Extract, Corallina Officinalis Extract, Coccinia Indica Fruit Extract, Curcuma Longa (Turmeric)Root Extract, Ascorbic Acid, Tocopherol, Thioctic Acid, Thermus Thermophillus Ferment, Glycerin, Potassium Sorbate

So far, loving this! I have super sensitive skin and it's causing no issues!
This serum is really nice and easy to apply! It’s on the thin side, so I like to tilt my head upwards and gently release a drop or 2 at a time onto my face. Rub it in from there.
If you drop this into your hand to apply first, you’ll be wasting a lot of product, so don’t go that route.
I do have some sun spots I’m looking to tackle, so hopefully this will help with those!
I also live in a city with high levels of pollution, so I can use all the antioxidants I can get!
I'm excited to see if this helps with some sun damage and spots that I've accumulated over the years.

Absorbs quickly
I like this ampoule. It has a nice gel-like viscosity and absorbs quickly into my skin and has not caused any irritation. I like that it has no smell. Since I have been using it, I have noticed a general lightening of the dark spots on my cheeks. I have noticed that my skin tone looks brighter since I have started using this. I will continue to use this ampoule in hopes of seeing even more improvement. Overall, I am very happy with this ampoule and think it does a good job of evening out my skin tone and lightening dark spots I have on my face making my skin look brighter, in general.
