Fourth time purchasing

I’ve been using this religiously for a year straight now. My skin is super glowy and youthful. I’m 33 and I’ve had people guess I’m anywhere from 19-25. It took away my wrinkles and dullness. It’s insane how different I look from last year. The formula is like a light weight cream, no oily/greasiness. I put on Laneige cream skin toner and then apply this vitamin C. It blends into your skin nicely and it can be layered. I hope this never discontinues!!

I received this serum as a sample and I’m really enjoying it so far! It has a lovely, delicious scent and a very pleasant texture. It feels gentle and smooth on the skin, and my skin feels incredibly soft and fresh after applying it. I’m really enjoying the experience and I’m curious to see what the long-term results will be with continued use. Definitely looking forward to trying it more!

Too little for the price

The product itself helped my skin tremendously removed a lot of my dark spots. But the amount that you get for the price is ridiculous. I went through one bottle in less than 30 days. I will not be repurchasing

Repurchased for years

I’ve repurchased this serum for years and always come back to it. The biggest standout for me is the texture—it feels like a lightweight moisturizer with the most beautiful velvety finish and gives my skin a healthy glow. I don’t use it expecting dramatic spot correction, but it consistently makes my skin look and feel smooth, hydrated, and makeup applies beautifully over it. Expensive, but one of the few products that’s truly worth it for me.

It resulted in breakouts

I really wanted to love this vitamin C serum given its reputation and price point, but unfortunately, it caused a significant breakout for me. While the formula seems high-quality, it just didn't agree with my skin. Given the small bottle size and the higher cost, I’d recommend patch-testing this carefully or checking the ingredient list thoroughly before purchasing.

Beware

This gave me such a bad acne breakout, I could not believe it. Also did not see any results. Hard pass.

Horrible reaction. Like acid on my face. Burns and peeling for over a month just to recover.

Love this product!

I am on my 2nd bottle of this product. I love it! My skin is smooth, even toned and bright. It’s much healthier looking. I exfoliate daily, use my serum and follow up with my fav moisturizer.

Must have vitamin C! Great for acne prone

This is the best vitimin C serum on market. I’ve tried most of them. This formula is light and gives and instant glow. It doesn’t clog pores and works flawlessly under makeup. Highly recommend.
