Unfortunately, on my sensitive skin from the first and only use since it was a sample, it caused an allergic reaction and as a girl mentioned below, within two hours my face was covered in pimples like acne.

The Metrok product didn't make much of a difference, I didn't notice any significant changes. However, when combined with the cream from the same line, I saw amazing results. I can live without this serum, but their cream is amazing

I tried it on samples, wore it for about a week. It leaves a nice feeling, yes, but I am concerned about the strong smell of alcohol, which is probably present in large quantities in the product. I don't think the ingredients are so carefully selected to justify this price, and although I wanted to buy it, I don't think I will in the end

I wonder why it has good reviews. I got pimples all over my face. It was like I had acne. It also clogged my pores. I stopped using it and calmed down. Then I felt sorry to throw it away and decided to use it on my neck. And there I got pimples. In terms of texture, it is lightweight, you don't feel like you're wearing it. However, it doesn't leave that luxurious finish and filling on the face that other serums provide, like Clarins' Double Serum, which I consider simply outstanding, or Dior's Capture Total. There are better serums on the market at this price. For me, it's not worth it. L'oreal's Revitalift from the supermarket is better than this Lancome serum

Amazing serum, after the very first application you can tell that it helps and revitalizes the skin. After the first week of use, the skin glows, appears more firm, and eliminates discoloration. It shows the skin refreshed and gives it a wonderful texture and color harmony

Excellent serum. I have oily skin and I am generally a fan of Estee Lauder, but her best-selling serum does not suit me well. This one is amazing, with a nice milky texture, it absorbs immediately and you feel your skin moisturized and glowing from the first application. It contains alcohol denat as the second ingredient, which initially scared me a bit, but it is a myth that alcohol (which one?) is "bad" for the skin. This specific serum evaporates quickly, so its job is to break down the oiliness in oily skins (like mine) and allow the ingredients to penetrate the skin. Therefore, I consider it ideal for oily skin types. If you have sensitive skin, maybe try the small bottle first. (Although the damage to the skin if we don't wear sunscreen in winter or summer is 100 times greater than alcohol).

I read the positive reviews and they impress me, really. I have been a customer of the company for decades, but this particular product did absolutely nothing for me. It's just water that you pay for and it's like gold on top. There are much more cost-effective products that make a real difference to the skin.

Learn to read the ingredients! It has fragrance and alcohol. Long-term, it significantly contributes to skin aging! Caution!

I have been using it for over 10 years!!! At times, I would buy others but I always ended up with this one. Now I know that twice a year (always during sales) I will buy it and it will last me 5-6 months since a small amount is enough to feel the difference on my skin. And I am 55 years old... I even use it occasionally as a mask... It is very expensive but unique for a product on the market. Irreplaceable for me.

The serum is wonderful. It absorbs easily, doesn't rub off, and is an excellent base for cream and makeup. Even if you apply a significant amount, it doesn't feel heavy on your skin. It doesn't have the typical scent of probiotics due to the fragrance. I wish the price was more affordable and I buy it at -25% or -35% off because I get the 50ml size, but it works wonders even if you have acne! However, we have been loyal to Lancome for so many years with my mother, when we had more money

The best serum of all time!!! However, very expensive... It has added fragrance to prevent the probiotics it contains from smelling, and even though it doesn't say it, it has a small percentage of alcohol. It gives an incredible glow, makes me look 25 when I'm 38!!! The plus side is that it doesn't rub off... If you didn't have to pay for the fancy bottle, it would definitely be much cheaper. But be careful! It doesn't replace the firming or anti-aging cream...

Favorite serum. Okay, expensive, but leaves the skin as it should be and not oily and heavy like other serums. It absorbs quickly. Does not cause acne. I love it.

It is a very expensive product for me personally, but since I have tried many brands, I will say that it does an amazing job. With a small amount, it absorbs immediately, you don't even have time to spread it and it leaves a silky feeling on the skin. From the first weeks, I saw a difference in my skin in terms of radiance. I have stopped using foundation and it's like wearing highlighter on my face even when I'm not wearing makeup. As for wrinkles, I can't give an opinion because I'm 30 and luckily the fine lines haven't appeared yet. Overall, I would say that if you have the financial comfort, buy it. Personally, I buy it but only wear it at night and it lasts longer.

One of the best serums I have tried, if not the best! Excellent absorption, leaves a velvety finish even from the first application!

One of the best serums I have tried. I noticed a difference in fine lines around the eyes quite quickly! It absorbs quickly and leaves a feeling of hydration and freshness without weighing down the face. It is a fairly expensive product (hence the 4 stars) but it is worth the money.

One of the best serums I have tried! It leaves a feeling of deep hydration and freshness without weighing down

I have tried the serum sample twice, which provides at least 10 satisfactory uses! I noticed a difference in marks and the texture of the skin, it absorbs completely and leaves the skin very smooth. It is an excellent product, however, it is very expensive, hence the 4/5 stars. You can achieve the same results with more affordable products. But if you have the luxury, it is worth it

27/7/2020 It is the best I have tried so far. You feel the difference immediately.

26/12/2024 Update: As a long-time user of the company and this specific serum, I have to say that either its composition has changed or they are selling products that are not genuine! Both the last bottle I purchased and the cream had absolutely no resemblance to the previous ones, unfortunately!

For me, the top term in its category is lightweight but effective.. It gives a nice texture and brightness to the skin. I have been using it for a year now!

Although I do not have any wrinkles yet, I bought the serum for hydration mainly, so I do not have an opinion on whether it smooths wrinkles. However, after 1 month of use, I can say that my face is indeed brighter and my skin smoother. A minimal amount is enough with the press of the dispenser for the entire face and neck! It does not stick and has not caused any irritations.

Very good serum, as long as we are grounded and do not expect miracles from a product. Very good texture, absorbs very well, and at least for me, it did not cause any irritation.

Incredible product, it does what it promises. It's worth its money and I recommend buying it. You don't need to use a lot, so it also lasts
