Wonderful antioxidant face serum. Light, like water, that is absorbed immediately. It is stored in the refrigerator.

I couldn't believe it but I saw a huge difference!! Now I use it every day and I love it!! Very lightweight, like water but with results!!

I can say that this particular serum has nothing to envy from much more expensive products. With systematic use, I noticed a difference in the radiance of my skin already from the first weeks. I should note, of course, that I did not have a problem with dark spots, but rather with the generally "dull" appearance of my skin.
My personal experience is that it absorbs quickly, leaving a slightly sticky feeling on the face, which is neutralized by the moisturizer/sunscreen that we should always apply on top anyway when using vitamin C!
On the downside, I would mention the smell of the serum, however, it is not worth deducting a star for this reason, as almost all vitamin C serums have this characteristic "metallic" smell.

Amazing and effective vitamin C serum. I have tried very expensive products and having skin with rosacea I use it comfortably without irritation. You can see the difference from the first use.

Absolutely worth it . No smell at all, I store in the fridge and use the mini bottle. Non irritating and I have rosacea.

I am buying this product for the second consecutive time. It is very easy to use and is absorbed immediately. I keep it closed in its box in the refrigerator. It did not oxidize at all!

I would like to add, because I read a review below, that if you see the color change even slightly (it is completely colorless like water) then you should throw it away. The vitamin C has oxidized!

It is a strong and effective product.

It is the best vitamin C serum I have ever tried. It does not irritate the skin and does a very good job. I have never bought this serum altered. After opening, it is kept in the fridge, not outside. I wouldn't change it for any other.

very good vitamin c, very light like water and leaves no greasiness at all. it is quite strong for experienced users!

Incredible product! Whatever vitamin C I had tried before didn't sit well with me or smelled very bad. With this one, I was thrilled

While I have been using vitamin C for several years, when I tried this particular one, after about a month it caused irritation and dryness in some areas of my face.

Very lightweight vitamin C, texture like water, not heavy at all. With oily skin, I really enjoyed it. I’m finishing the first bottle, I will definitely buy it again. I saw a difference in the texture and brightness of my skin and it combined perfectly with the rest of the products in my morning routine, without weighing down my face. Its price is 100% value for money. Give it a chance, you won’t regret it.

smells of luncheon meat and leaves my skin feeling drier than normal, but i have dry sensitive skin so i think it's a me problem.

It gives radiance to the skin, absorbs quickly, nice feeling on the skin, the smell is not pleasant but it does a good job!

Personally, I don't like its smell at all but as a product it is very good. I wouldn't use it again as the scent displeases me, it smells like something acidic or metallic, but for anyone who can tolerate it, it is a very good choice.

I keep the bottle in the fridge to increase its shelf life. At the beginning of use, it stung the skin a bit. Only during the application of the serum!

After I applied the rest of the skincare steps - it stopped. Sunscreen is absolutely necessary!

You don't need a large amount. Learn from my mistakes)))) you need 3-4 drops for the whole face with good application so it absorbs completely. At first, I used way too much until I realized that wasn't right. And how did I realize it - I was yellow all day :-)))))))) !!!! so be careful. It's not a stable form of vitamin C, so you need a small amount and to spread it very well.
I'm still using it.
If anything changes dramatically - I will update.

Watery serum, satisfactory vitamin C content, at the right pH and a good complex & ratio of vitamins for optimal absorption, at an excellent price! You simply place it in your palms and spread it all over your face, neck, and décolleté, very easy to use.

Excellent product. Transparent liquid, with very fast absorption. Easy to combine in many different routines.

A serum as liquid as water, this makes it difficult to apply but it is absorbed immediately. Sensitive in its preservation, so it needs to be kept in the fridge.

Very satisfied with the product. Its texture is like applying water, it absorbs immediately. Without artificial fragrance, so it has that smell of rust. Brighter skin, softer without irritation.
