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.

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!

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.

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.

Caution when purchasing from this vendor!
Not sure if this is a manufacturer or Amazon delivery issue. The liquid contents are below the letter M. No wonder it was on sale for prime day. Rip Off!

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!
