The Vitamin C 13 Serum, 0.67 fl oz (20 ml)

After you buy it, it says on the package to store in the refrigerator. It comes with a cap and you get a dropper next to it. Vitamin C is very difficult to maintain, alot of other products say they sell vitamin C but its not real, this company took it seriously, sold pure vitamin C and gave instructions for use. The serum is very smelly and sticky. I suppose that in order to get real vitamin C and not an impostor one has to deal with bad smell and hard maintenance. That's why I probably won't buy again, but if you're looking for real vitamin C, I recommend it. 13% is i think a good percent, and vitamin C supposed to work well with the other ingredients they chose

I use it every day in the morning and I have genuinely noticed a difference in skin brightness. It just looks healthier. it definitely smells like cat food a little bit but the scent doesn't stay long and isn't noticeable to anyone else. I've ordered two so far and the quality has always been high. just be sure to keep it in the fridge.

I’ve never used a specific high quality vitamin c serum before. I am so impressed with this product. I get daily compliments on my skin and I’m pretty sure it’s thanks to this product. It makes my skin glow and has dramatically reduced the colours of my under eye bags in a few weeks. This product is now a daily in my routine!

The 13 is also very nice. I didn’t mind having to switch to this strength for a while. These serums make my skin so glowy and I notice when I stop them. The scent, much like anyone would tell you, is funky. I always am reminded of tuna. But, it goes away quick. The texture is oily, but it doesn’t leave an oily finish.

i love this vitamin c serum. i can immediately see a difference. i struggle with hyper pigmentation & this helps with a few uses. the scent is not too over powering. it is quality & affordable. i like it so much, i have repurchased it like 4 times already. hoping this stays affordable.

I’ve been using this supplement for a while and I’m really impressed with the quality. The ingredients feel clean and effective, and I noticed a difference in my energy and overall well-being. The packaging is great, the price is reasonable, and the delivery was fast as usual with iHerb. I appreciate that it’s easy to take and doesn’t cause any discomfort. I will definitely keep using it and highly recommend it to anyone looking to improve their daily health routine

This product Will clear and brighten the skin tone, and heal pigmentation and blemishes, but first it works deep in the skin tone resurface impurities. There may be more blemishes before the product starts to visibly work because it works deep in the skin. Good for everyday use however the product is a bit strong. The scent is also not great and it’s difficult to know if the product is still good but it seems the quality of vitamin c is a strong scent.

The most wonderful Vitamin C you may ever find. I am buying again cause this product is a high-quality one. Scent is acceptable. Remember not to use water after Vitamin C on your face and you will see the benefits of using it. It's not gentle but it's worth it, you need only to control frequency.

a brightening powerhouse! It absorbs quickly, feels lightweight, and gives my skin an instant healthy glow. With consistent use, it noticeably fades dark spots and evens out skin tone without irritation. A must-have for radiant, smooth skin! However the scent is really awful sometimes I hate putting it in the morning. I bought it many times because it works well with my sensitive skin. It’s gentle
