Very good product with daily use after a month I see a noticeable difference. It's worth buying the large bottle

Good serum, you feel it light on the face, it provides shine, the results are visible. Fragrance-free, of course. You keep it in the fridge. Personally, the only similar or even better ones I have tried are some random brands of around 6-7 euros. Anything "good"/expensive/from big companies feels heavy on my face, what can I say.

I had never tried products from this company until a friend who knows about skincare recommended them to me. I have been using this particular product for less than a month in combination with The Ordinary Niacinamide 10%, and I can already see a difference in the discoloration on my face. It feels nice when applied, and when combined with a moisturizer, I enjoy pampering my skin. As for the scent, nothing special, but you can't have it all...

Very good product to start with vitamin C. It has an oily texture but absorbs quickly and then you can apply sunscreen and makeup without any problem.
I didn't understand the tingling sensation that the company mentions for new users, but it also depends on the type of skin you have.
On my oily, acne-prone skin it worked very well. It didn't make my skin more oily, nor did it cause any breakouts. On the contrary, it provided visible radiance and helped heal and fade existing acne.
I have already finished 2 bottles and I would choose it again in the future.

I think it's perfect to start with the application of vitamin C. I don't have any particular issue, apart from a little dullness and some discoloration on my neck. I'm expecting to see overall improvement, but it needs more time. I must note that the first few times I used it, I felt some slight tingling for a short while. Now, my skin seems to have gotten used to it, although when I overdo it, it causes a slight irritation/redness in more sensitive areas. It's quite fluid and absorbs quickly.
