The product is a disaster. It leaves streaks. It sticks. It doesn't absorb. It even stains the pillow orange. My skin looks like a carrot

Black carpet packaging. Definitely wouldn't buy it again. When you try to put the dropper inside the bottle, the serum spills around. I keep it in the fridge because I read that it preserves vitamin C better, but this one becomes too runny

Good for a while. It came to me as a sample with a regular order from a pharmacy in its bottle. The first 2 weeks I loved it, it made my skin soft and bright, etc. Unfortunately, it oxidizes very quickly, so from the 3rd-4th week (the liquid was deep orange) and onwards, I had opposite results, especially on my neck where I applied it, I got filled with allergic pimples.

I knew that it oxidized quickly and that's why I kept it in a shady place and took great care of it... but it didn't work.

The product is what it says. Whether it works for our skin is another thing. I, who have acne, do not find it suitable to use again. So, from me, it's a no. However, I buy other products from the company suitable for my skin and I am satisfied

It does absolutely nothing - it breaks quickly - it doesn't match any cream on top, pieces come off. One star because it is mandatory.

It has silicone in it, you can tell because it leaves that velvet feeling that clogs pores and is generally the worst thing for proper skincare. So you give 30 euros to do good for your skin with vitamin C and you just cover it with silicone, it's one of the first ingredients!!!! Tragic product in the year 2024 when there are much cheaper and more effective ones, and as a makeup base it's terrible, whatever I put on top moves around. And the worst of all is that as soon as I opened the sealed (I emphasize this) bottle for the first time and heard the sound of the serum being unpacked, it already had a yellow-orange color!!!! So the formula is so bad that it spoils on its own!!!!

I have oily skin but I haven't had pimples for years. From the first week of use, I developed cystic acne, my skin was painful, and I had internal pimples everywhere. As soon as I stopped using it, everything disappeared

After one month of use, I didn't see any difference. I filled with pimples and my skin seemed more dehydrated and tired than before.

I saw the reviews and I said it's impossible for this product to have so few stars. The first time it ended up in my hands by chance. Someone had given it as a gift to my mother, who didn't use it, so I took it. I have oily sensitive skin prone to redness and I don't know what I would do without it. It is a crucial part of my skincare routine. My skin cleanses and glows when I use it regularly.

Wonderful serum!!! Honestly, I wonder about the comments!! Personally, I have been using it for 1 month (it lasts halfway) and I store it in the fridge. I also make sure to close it very well and always keep it in its box. My skin is normal and it has truly brightened my face!!! I don't think I will change it!! 10/10 from me!

I have not tried this specific product, however, the videos promoting it when you click on this product are not accurate. DO YOUR OWN RESEARCH and consult your own dermatologist before starting to use vitamin C. If not used correctly, it can have harmful effects. So, BE CAREFUL. We don't watch a video and say it's perfect, I want it too.

Amazing product. I am very satisfied with the results. I only put 4 starts because of the packaging- I do not understand why La Roche Posay keeps insisting on having this product in a dropper and transparent bottle. The formulation is extremely unstable and oxidises within weeks- after which it is useless.
I got around this by purchasing a black, opaque pump and kept the product in the refrigerator. This kept it from oxidising and I managed to finish the bottle with absolutely no change in color. My solution worked great- but I should be put in a situation to have to find a solution. They should just change the packaging!

It caused dryness, pimples, and overall bad skin like tired. Exactly the opposite of what it promises. I had to throw it away and it was expensive. Maybe after a while of use, it actually works, but honestly, I couldn't even use it for one more day

It smells strong for me. It doesn't absorb easily and leaves residue no matter how little I apply and wait. I do not recommend it

Apart from what you have already mentioned personally, since I started using it, I noticed that the product peels off on the skin. Unacceptable

I will probably repeat what has already been said, as this specific serum not only turns orange and stains everything, but it also has a very unpleasant smell, which happens very early on (it doesn't need a month to pass) and does not justify the inconsistency between usage and quantity.

For me, the best product on the market at a relatively good price. The face shines with the second - third application and you immediately notice the difference. I have already recommended it to all my acquaintances since I buy it almost every month! Daily use.

It is the first product I bought with vit. C. The texture is a bit sticky, which personally I am not a fan of, but it leaves a nice feeling once absorbed. Unfortunately, it didn't suit me as a product and I gave it to a friend. Regarding the quick oxidation that I see in other comments, I didn't have any issues.

I haven't seen any difference in my skin. But compared to other serums I have tried, it leaves a nice feeling.

Very good... My skin shone from the third application... I just received the third bottle today...

It spreads very easily, has a nice texture, and dries quickly. It leaves a nice feeling on the skin. I haven't yet noticed if it has any results.

After one month, it turned orange and left color.
Also, I didn't notice any difference on my face.
I didn't buy it, Garnier has a better serum with vitamin C.

First contact with such a product, I was not satisfied at all... Initially, my skin is combination... It has a nice scent and absorbs very quickly into my skin, almost immediately, but it oxidized in less than a week (unacceptable)... Also, the dispenser does not release much product and a significant amount of product remains on the cap, so it goes to waste... It definitely does not deliver what it promises... I have been using it for about a month and I have not seen any difference in lines, radiance, or hydration! Disappointing because I like this particular company and obviously I will not make this purchase again... It's a shame for the money I spent!

Very nice serum, I bought it to wear every morning under my cream. Of course, I also apply sunscreen afterwards. It brightens the face, it's a bit sticky, I think serums from brands like L'Oreal have a nicer texture, but I don't consider this a problem. It absorbs immediately, has a nice scent that disappears right away, it doesn't bother and moisturizes the face instantly. I will definitely buy it again.
Update: The only negative thing is that if you rub your face a little, it produces clumps. It's somewhat annoying, I will see over time if it's annoying enough for me not to repurchase it.
Update 2: When I use a smaller (and recommended) amount, 2 drops on the forehead and 1 drop on each cheek, there are no clumps. Obviously, when we use too much quantity, it can't be easily absorbed. Also, even if I apply a little more, if you let it absorb for 3-4 minutes before applying cream, it still doesn't produce clumps.

I loved it from the very first application! I have pores, which were noticeably reduced immediately. I have been using it for 5 days and my face looks cleaner and more radiant. It also applies comfortably as a primer for makeup. As for its maintenance, I have it stored in a drawer and tightly closed, so it doesn't come into contact with light and air. It is definitely a product that I will continue to purchase.

Update:
After 2 months of daily use, I would like to mention the following:
In the third week, it started to gradually change color (even though I had it tightly closed and stored in a drawer). As long as it had the transparent color, it gave incredible shine and clarity to the face. However, after oxidation, it lost its color. Also, in the last week, I noticed an unpleasant smell, but it didn't cause any irritation. I don't know if I will buy it again, as its effectiveness was only as long as the product was fresh.

It's perfect! It does what it promises, I'm in the first weeks and my skin has already changed! I loved it.

Update: Unfortunately, it oxidized very quickly, in less than 2 months, even though I was very careful and always kept it in its box and closed properly. I have already ordered my next vitamin C from another company!

I really like and trust the company. I have bought all the vitamin C and retinol bottles, they are amazing.

I buy it 2-3 times a year because the bottle, with proper use, doesn't last long. However, it is exceptional!!!
