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!

Great and effective Vit C
My skin is softer and brighter- plus any time I do get a breakout it fades faster - after using this. I’ll keep purchasing. It’s also non irritating like many vitamin c products tend to be.

Great for sensitive skin
Great vitamin c! Glides on easily and doesn’t dry out my skin. Very tolerable for those starting vit c or those with sensitive skin!

Smells fantastic and fresh like oranges, repurchased because I like it!
I liked it so much I repurchased. It smells fresh and feels good. I know I am supposed to use a vitamin C, and this one was recommended to me. It really seems to be high quality. I top it with a peptide serum in the morning.

A must try!
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!

The best skin product ever
I was told about this product by a beautician and it's been a revelation. My skin is much softer and I need hardly any moisturiser after 4 months of use. I've recommended it to my sister and son, who both suffer from very dry skin on their face and they saw an immediate improvement. I use 4 drops every morning and use Medik8 Retinol 3TR every other evening. I love it!
