Firstly my skin reacted with redness for few seconds, after this everything is fine. I use it everyday with Sunscreen from Dr. Ceuracle and it works just great.
Great vitC serum, not greasy and absorbs fast in your skin.
I can't say I'm loving this product... It's actually not doing anything for me, except it makes my skin a bit glossy but in an oily way... Maybe it's better for dry skin. I will probably use the bottle (it's really big, though) but I will not buy it again.
The serum is really good
I've been using it for a short time, but I don't notice that it gives much luminosity. But it has an easily absorbed texture and has no smell. I've noticed little breakouts but I'm not sure if it's due to the product, or change of season. I have dry skin.
I love all the products that i buy here
Very lightweight
Didn’t notice any difference in my soon when using this. It’s not hydrating so I stopped using it in order to use my usual products.
🤩
it's probably ro early to say something about a visible change but it has no smell and it never irritated my skin no matter how much I used. I recommend keeping in the box or in a dark place or it might oxidate or something
This ampoule is very lightweight and not sticky, very easy to use, clear dark-spots!
can't say ive noticed much of a difference tbh!
This ampoule is a nice addition to my routine. It gives my skin a nice glow but don't expect miracles.
It burned for the first few uses but once my skin got used to it, it was smooth sailing. Not a fan of the pipette packaging though.
Very lightweight and not sticky
Hydrating serum, non oily or sticky, very easy to layer. However, I don't see any major improvement on my skin texture or pigmentation. In my opinion, the Jumiso multivitamin or Goodal are much better Vitamin C options.
I use it and now my mom also is using her second bottle! We love it!
I am loving this toner as it is very nourishing and makes my skin brighter and healthy looking.
my skin appreciate this ampoule a lot, love that it absorbs well and does not have any bad reaction to my sensitive skin.
Nice
I keep on repurchasing it ! My skin never looked better.
I like the feeling and consistency of the product. It is light, does not stay on the skin like a layer. I feel it is compliant with my other skincare products. I don't have the idea the 'brightening' claim is working for me. But my skin feels hydrated.
I have combo skin and I'm loving it! Pa ra pa pa pa. I'll stick to this one from now on. It's not oily and it brightens while giving some C juice to my skin.
Will always have a place in my skincare routine. Don't know about the stability of the Vitamin C, since that is very hard to stabilise as a serum. But the niacinamide is def doing it's job!
Just started
Serum that helps and isn’t sticky!
I’ve been using it for 3 weeks now everyday and still have seen very little changes, but they’re still there sooo… still great!
I have been using this every morning for 4 weeks now and I really like this serum. I feel like my skin looks more glowy and my acne scars look less visible. The texture is very good and the product gets absorbed quickly.
not only does it contain vitamin c but also niacinamide !! it really brightens up your skin complexion and is suited perfectly for everyday usage !
I've intoduced this ampoule to my routine recently. No weird smells, feels great on the skin, which looks a bit plumped up and more "glowy". Actually got a compliment from my colleagues about my skin looking overall nicer... Will continue to use!
I've been using it for a little over a week and I like it so far, seems to be doing about the same job as my previous niacinamide serum.
Does what it supposed to do!
Not sticky, haven't used it for a long time but niacin should work.
