Heavy product if you have oily skin. Strange scent and texture but the face shines on dry skin! I won't buy it again, too expensive. Better go with the ordinary

I have combination skin and I can say that it feels very heavy on me, it has a strange smell and texture, and it oxidized quickly. I would not buy it again as it does not suit my skin and I only used it because I didn't want to throw it away.

I have oily skin and generally I don't mind a heavy feeling from a cosmetic product. I bought it to use it at night before sleep. The scent is awful, and I consider myself someone who is rarely bothered by scent and texture as long as it does the job. It was yellow from the first moment and it felt like I was applying olive oil. I immediately gave it to a friend with normal skin, it suits her better. I won't buy it again, there are countless serums in the market. It's a shame because I highly appreciate Korres products

I don't understand if it is really as it should be because the first one I bought had a smell of spoiled cosmetics but a good texture. I contacted the company and they sent me another one but it also smells spoiled and has a thick texture. The color is pink-yellow and not transparent, from other comments I understood that it shouldn't be like that. I don't know if it's because in both cases it came with a courier on very hot days, but for sure I won't put it on my face.

If it had 0 stars, I would give them! Initially, the quantity is excessive if you consider that you have to use 3-6 drops per day! Vitamin C on its own is unstable and easily oxidizes! You will notice this in the color change from white to yellow! Mine oxidized in the second week, so I threw it in the trash! I always kept it in a cool and shady place and well closed! The feeling it leaves on the skin is sticky! It contains oil and water! Theoretically, this is good! In practice, no matter how much you shake it, you will never be able to mix the product! You will just make bubbles. And the scent is overly reminiscent of Myrto! It smells like our grandmothers when they returned from church on Sundays! Truly the worst scent by far! And no effectiveness at all! At least for me!

I don't know if it does what it promises because I simply threw it away within 2-3 months. And that's because it changed color due to the oxidation of vitamin C. It turned dark orange and the smell was awful (not that it smelled nice before oxidation). Also, it is so greasy that you don't need to use a lot (I have very dry skin), resulting in this bottle being wasted since it oxidizes so quickly.

Transparent composition, which however no matter how much I shake the bottle before application, does not unify. Additionally, the product that remains each time inside the dropper from the previous application is separated and does not unify at all from shaking the bottle. It leaves a very greasy texture when applied.

It does what it promises, it just requires a very small amount because it doesn't help for oily skin because it doesn't absorb easily

It needs a good shake before using it.. To me, the oil smells quite like olive oil.. It feels like I'm putting water with olive oil on my face.. The applicator is not convenient at all.. It leaves the face relatively oily.. I wouldn't recommend it for oily skin.. I prefer to use it at night before applying cream.. If I have to do my makeup immediately in the morning, I don't prefer using it right before my makeup because it takes a little while to absorb..

Apart from the greasiness it leaves on the face without providing much hydration, I noticed pore enlargement after a month of use and a strange allergy accompanied by redness, which no product has ever caused me in the past, as I am not allergic. I like Korres products, but this one did not sit well with me at all.

Very nice product! From the first application, I saw a big change in my skin! It doesn't leave any greasiness, I just need to let it absorb for 3-4 minutes and then I can easily apply makeup! It makes my face look brighter and calmer. I will definitely buy it again!

I have been using it for a month now and I am very satisfied. I only apply it at night because the oil bothers me during the day, but before sleep it is perfect. In the morning, I wake up with a very fresh and revitalized skin. I will definitely buy it again

Very greasy even for dry skin. It should be finished within a month preferably, otherwise it oxidizes. That's why there are complaints about the scent, which initially was nice but then it smells bad. It also changes color if it stays for a long time. It didn't harm me, it just lost its effectiveness. It is not advisable to use more to finish it, as it has inhibitory effects and clogs the pores. Personally, I use it on my neck, décolleté, and hands to finish it!

I am wonderful!! I have been using it for a while now and I have noticed various changes on my face...my face looks more radiant and refreshed...it smells amazing!!! I have very dry skin, especially during the winter months, and now my skin is soft without any flakiness...I will definitely buy it again

I have been using the booster for a month now, and I have noticed a significant difference in the tone and quality of my skin. The only downside for me is that since it is a dual-phase product, it leaves the skin slightly oily. However, despite this, I overlook it because of the results. I recommend it!

Looking for a serum with vitamin C, I came across this one and decided to try it. I have been using it for about a month. The product is oily because it is a dual-phase serum. Since I have a very oily face, I only use it at night before applying my moisturizer. Another reason why I wouldn't use it in the morning is because, due to the vitamin C, you need a very good sunscreen protection. Surprisingly, with just one use a day, I have seen some improvement. I wake up and my skin is much more radiant, smooth, and without imperfections! I would buy it again!

When you see vitamin C, the first thing you think is that they have definitely stabilized the C because otherwise it doesn't make sense since it oxidizes in a short period of time. Initially, I used it and I liked it quite a bit. You shake it, and with the dropper you put it on your face, personally I massage it for 1 minute.
However, in the 15 days of daily use of the product, its smell changed for the worse - I would describe it as a plastic rubber - and also product comes out from the bottle cap where the dropper connects with the cap. Consequently, oxygen comes into contact with the product.
As for effectiveness, maybe I can discern something subtle. But nothing significant that would make me prefer it again.

The serum is part oily and part liquid. It needs to be shaken and mixed. It runs more than normal from the dropper and if you don't pay attention, it can stain you. Very nice scent but it left a heavy feeling on my skin (combination-oily) and a greasiness that wouldn't go away, which I can't stand. I can't speak about effectiveness because I didn't continue using it due to the sensation, but the ingredients are quite good and it didn't cause any irritation or allergy. If they improve the absorption, it will be very good. The strange smell after a few days that friends mention is due to the oxidation of vitamin C because it comes into contact with the atmosphere when you open the bottle to use the product. This indicates the oxidation of the vitamin, which is naturally sensitive and besides the unpleasant smell, it loses its effectiveness. Company's fault, it needed different packaging.

It really does what it promises! I have been using it for two to three weeks and the marks I had from acne for years are starting to disappear! I didn't expect it. Additionally, it gives a glow and hydration to the face. The only negative is that it leaves a greasiness on the face since it is an oil. However, this greasiness is relatively quickly absorbed!
