I will never use another vitamin C serum again. This one is so moisturizing, effective and just perfect. My hyperpigmentation is almost all gone, and my fine lines have smoothed out soooo much. I love how smooth the application is and it wears well under makeup. Will buy again.

Pretty good vit C serum
Pros: I received a sample of this in the radiance edit. I have tried so many vitamin c serums, but was always put off by the smell. This is the first vitamin c serum I have found, that has a relatively mild scent. The serum itself has a wonderful feel, and sinks right into the skin. The results are subtle, but definitely there-- it gives a lovely glow to the skin. Cons: Price The packaging is rather fragile. I dropped my first first sample, and it shattered on the bathroom floor. It had impressed me enough, by that point, that I ended up buying a full size. But for something so expensive, I feel like the packaging should be a little bit more durable.

Nice product, fragile packaging
I got a 15ml bottle of this in a Cult Beauty edit. Used it for about five days until the bottle slipped from my bathroom shelf and smashed broken onto the floor. That was really unfortunate because I was actually very much enjoying using the serum. It was milky in texture, slightly oily too, but sunk in the skin well. I do remember it having an odd smell though. Anyway, too bad that the bottle was made of thin glass. The dropper it came with also didn't really work so I just poured the product onto my palm. Maybe this is different with the full size. Unfortunately I won't be investing in it because I didn't get to fully see any results. But if you get this, beware of dropping it!

CAN'T LIVE WITHOUT!
Wow. This serum really took me by surprise. I've been watching the brand for a while on social media and was so excited when I was able to shop it on Cult Beauty since I don't live in the US. My skin has seriously never been more radiant. My dark spots have faded drastically and fine lines have smoothed. I have recommended this serum to many friends who also love it. Such a great find!

Great serum and amazing results!
I discovered this serum with the The Radiance Edit and I’m in love. At first the smell was strong but after some applications you get used to and it don’t remain. This serum game me glow and my skin feels tighter, I’ve been using it for a week and people can see the results. I have sensitive skin and this serum is great. I will repurchase 100%

Wow!
Received this serum in The Radiance edit Beauty Box and I’m amazed! After using this on PM I woke up with an incredibly good looking, even-toned, smooth, soft skin and there’s a huge difference after using this on am & pm for less than a week. This must be my new favorite serum. My skin is sensitive and this didn’t irritate the littlest bit, no redness. While using this, I have had less redness than normally.

Nice surprise. Like the brand
First serum I actually saw results. After a week of use my skin looks brighter and my sun spots have faded. The smell is pretty strong and I didn’t like it at first but after a couple of days I get used to it and now I even find it pleasant. Ordered face oil too now.Â
