”19, M, Oily Skin. This product is incredible. I have a lot of post acne scarring, general redness, and uneven skin; introducing C20 into my routine changed my face in a matter of weeks. I cant even really tell what it did- what I know is that my skin’s redness is much more subtle and that many of my imperfections have been smoothed. I put this on after cleansing and toning, and while I don’t know any of the science behind it, I feel like I can say that it helps all the next products i use become more effective. Make sure you wait 20 minutes after using it for best results.”

”I started using this serum about a month ago and I have already seen big changes in my skin. I am in my mid-30s and suffer from Melasma and fine lines. After a month of use my skin texture is so much smoother and the Melasma that is above my upper lip has faded a lot.”

”I have combination/oily skin. After about using thus product for a month, I saw that my acne has improved, my pores were reduced a little in size, and my skin complexion became more even. I would buy this again and I definitely recommend this product!”

Went bad immediately

As soon as i received this product i immediately took precautions because i’ve read about how to take care of Vitamin C serums (avoid direct light, keep in cool areas or fridge). But the color still turned dark orangey after a month of opening/using it. Really sad, but i couldnt use it anymore after that, because when the color changes, it looses effectivity. Havent used it long enough to notice ant difference on my face. Too bad.

love this

This helped lighten dark spots including my undereye and helped fade my acne scars. I make sure to always use this at night as it makes my face sticky and so I won't have to worry about sunlight since vitamin C can make your skin sensitive. I leave it in the fridge so it goes cold on my skin. 3 drops is all I need for my face and neck. 🍊

most people don’t wake up with glowing skin, at least not without some effort the night before! !! having glowing skin when you wake up is the dream and this is my key to waking up with that enviable glowww. a word of caution: because serums are super potent, more is not always better. be careful before piling it on. powerful ingredients can irritate sensitive skin (proven and tested).

Hello brighter face! Good bye Acne Marks!

This is my go-to Vitamin C because it is cheaper than other brands but works the same. Every night I apply and wake up with brighter face. The only down side in this product is its sensitivity in the way you store it. You need to refrigerate this and tightly close the lid but will still just last you for 1-2 months.

holy grail vitamin c serum!

This was the first vitamin c serum I ever tried and I've tried other vitamin serums after but Ii always keep going back to this. The serum is very concentrated so you have to get used to it for a bit, but when you do, the results are mind-blowing. I pair this with Tiam's vitamin c sleeping pack and I always wake up to such glowy skin. It really helped with my dark spots and hyper pigmentation.

Holy Grail!!!

I have tried different vitamin c serums like Wildleaf and Dear Klairs but this gave me the best results! Pimple marks are gone in just one week, and with a help of a good moisturizer and sunscreen, it gently removes blemishes and pigmentation on my face. It did not break me out, plus it is super tipid! I am now on my third bottle :)
