This serum is very interesting one, it has oil like texture but doesn't have oil in the ingredients. It might feel at first that it's not absorbing, but I give it a time to absorb and it's job so I wait 5-10 minutes until I apply cream that's what was recommended by a skincare YouTuber I follow. When you apply cream it slips if you use same finger you applied the serum, so I use my finger knuckles to "catch" the cream. Cream literally glides on top of this serum. I want a even skin tone from Vitamin C serums but I can't expect that in a short amount of time because studies show that it takes 12 weeks for a vitamin c to actually work and give results. It's about consistency and and build up effect for sure. I store this serum in a fridge since it's an active form of ...

I use generous amount everytime I use since it goes bad quickly due to oxidation. I like this serum and will definitely order again!

This is a fantastic vitamin c formulation. I use it every morning after I wash and tone my face. It goes on almost greasy (which freaked me out at first because I have very oily skin) but it absorbs beautifully. My skin is left looking radiant and dewy . After I allow it to absorb, I follow up with my SPF moisturizer. Not sure I would use this under makeup. While it does eventually absorb, it does still leave a slight oily residue (which gives the radiant and dewy appearance) that may not play well with makeup. Again, great vitamin c formulation for a really good price.

Very nice serum. I really love that is has three main ingredients that vitamin c serum should have. It has sodium ascorbyl phosphate, which is stable derivative of vitamin c, ferulic acid and tocopheryl acetate. It doesn't have any scent, I used it in my morning routine, before sunscreen. For that price, the quality is very good, and because it is vitamin c derivative, people with sensitive skin can use it. I didn't see any major changes on my skin, but also I can't say it didn't do anything. It gave my skin a nice glow, and my sunscreen didn't peel off.
Vit C Serums with L Ascorbic acid can be sensitising on skin types but it is the most active form of vitamin c so sometimes it can be tricky. I was able to use this 15% formula without any sensitivity. It goes on really lovely, feels hydrating on the skin and within a few days you can definitely start to see the difference. I love this vit c serum and definitely recommend it to someone wanting to try l ascorbic acid. I love this and use it every morning. Light viscosity and light smell. The product is clear, but it does brown ever so slightly overtime, but still works well. My dark spots are appearing lighter more and more each day. I’m sure in a few months my skin will be even overall. I love the packaging, the opening for the pipette has almost like a suction ...

I love the packaging, the opening for the pipette has almost like a suction effect, so the product is sealed properly at all times and rarely is exposed to air. Which is very important, especially for Vitamin C. Great product!
Lately I’ve been skeptical about trying Korean skincare products and that because of the unsuccessful attempts in my past. However, this brand is new for me and I’m very pleased with how “straight forward” they’re with their ingredients. This serum is very gentle & suitable for sensitive / oily skin, it doesn’t have any strong smell and skin absorbs it very fast. I use it everyday and I don’t mind purchasing again, actually I wasn’t hesitant about trying another products from this brand, so I ordered the Niacinamide serum and I can’t wait to try it.
You may know that vitamin C is important for our face routine. I use it twice a week after toner. It stays sticky for few minutes and then I put cream with no acids. It has really particular scent that to me it seems like something smoked :) but it doesn’t stay on the face. The size of bottle will last more less 2 months. You will notice your skin brighter it used with frequency. Good quality as everything of This brand. Working and gentle product !
I have used this serum for almost a week now, and really like it so far. It doesn’t have a noticeable scent. The texture is just a little bit viscous. I use two droppers full so I can cover my face, neck, and décolleté. I have had zero irritation so far, even though I have rosacea and somewhat sensitive skin. There is no burning, tingling, or stinging sensation even on areas where I’ve had some irritation or a breakout. I’m not noticing any benefits just yet, it’s going to take more time to see whether this will be helpful for my hyperpigmentation. This brand is one of my favorites for affordable, quality skincare products.
This serum is packed with the goodness of vitamin C, and it has truly transformed my skin. With regular use, I've noticed a significant improvement in my skin's brightness and overall complexion. It has helped to fade dark spots and even out my skin tone. he lightweight formula absorbs quickly into my skin, leaving it feeling hydrated and refreshed. I also appreciate that it comes in a dark glass bottle, which helps to preserve the potency of the vitamin C. If you're looking for a vitamin C serum that delivers visible results and has a delightful scent, this would be the go to! Amazing quality
