Gentle, Effective, and Great Value – My Go-To Vitamin C Serum
I’ve purchased this serum three times in the past 15 months and use it every morning. Each bottle lasts me about 4-5 months, making it a great value. Unlike many vitamin C serums that leave your skin feeling tacky or sticky—or cause other products to pill—this one absorbs beautifully.I struggle with sunspots (thanks, Dad!), and this has faded them to the point of being nearly invisible. I have dry, sensitive skin and have had no issues using this product. While the recommendation is four drops, I tend to use more, applying it to my face, neck, and chest, then using any leftover on the backs of my hands. The serum has a lovely silky feel and a mild citrus scent that I really enjoy.One thing to note: the glass bottle and dropper require care. I accidentally dropped a dropper in my sink, and it shattered. Thankfully, I already had a backup bottle ready.At 57, I know the importance of following up with a good sunscreen, and I highly recommend doing so. Overall, this is an excellent vitamin C serum that delivers real results and is well worth the investment!

A must try!
The media could not be loaded. I've had my fair share of Vitamin C serums that left my skin irritated and prone to breakouts, but this one is a game-changer! It's surprisingly mild, yet still delivers noticeable results. My skin feels brighter and more even without any of the harsh reactions I’ve experienced with other formulas. It’s gentle enough for daily use, and the light citrusy scent is a lovely touch—it’s refreshing without being overwhelming. If you’re looking for a Vitamin C serum that’s effective but won’t irritate, this one is definitely worth trying!

Sooo goood!
It works! It’s been 10 days am and pm regular care, I used medik 8 tonic as well. I am 33 y.o and ,LOVE THE RESULTS. My skin not only looks much better but feels to touch better, my forehead wrinkles became less visible and more moisturized, I actually can not believe to such fast results. Someone was complaining on absence of smell but I do smell citrus otes in serum which is nice. Love it! Would def recommend and buy again

Top 1 best vitamin C, even for mix skin tone
One of the top three vitamin C I’ve ever had. This product is really good. I read the reviews and they say it’s too oily, but it’s not. Just used a little bit. LESS is more. I am putting four star to make it look human. I am a real customer and five makes it look sus. But yeah, it is five star.

Gave me an intense, itchy rash that required topical steroids
I want to preface this by saying that I have other products by this brand that I love, but this one did NOT work for me. Worse, it broke me out in an itchy rash that required a steroid ointment. I don't usually have overly sensitive skin, and I have no known allergies. The first time I tried it (at night) my skin did not react immediately, but I woke up the next morning with a bright red face and itchy bumps all over my skin. I still wanted to give it the benefit of the doubt, because I used other skincare actives the night before, and I thought that maybe it was just too much. The next night, I applied it to my decollete and neck, where my skin is less sensitive, and no other actives were used. However, the rash I woke up with was even worse, and I ended up having to use a prescription-strength steroid cream for two days to calm it down. I did return this product for a full refund, there was no issue.
