See brighter, more even skin day by day. C Serum visibly diminishes signs of aging, allowing your youthful, radiant complexion to shine through naturally.

Finally a Vitamin C Serum with No Irritation or Itchiness!
Vitamin C-based skin care has been popular for a long time, and although it comes from various brands, many of them are quite irritating especially for sensitive skin, but this C serum doesn't have itching or irritation. After using this, I've been having less breakouts, and even if I fall asleep with my makeup on, my skin is less likely to get rough.

Absolute Favorite, Hands Down
I'm not sure what it is about this stuff, but it just feels expensive. It's not too thick, and doesn't feel slimy like a peel off mask or seaweed serums I've used in the past. You can feel it engulf your face and seep in, after about 10 minutes it's totally absorbed and the shine from the gloss is gone. It's my favorite part of the routine.

I think that C serum is the best product that evens skin tone. I had my son try this for his acne, and it diminished! Now he's using this with a subscription. My husband gets eczema in the winter, so we started putting this on spots where eczema likely occur, and they've gotten better. Thanks to this product, I don't need to see my dermatologist as often.

My skin felt dry the first time I applied it on my face. But after a few months of continued use, it felt less and less like that, perhaps due to my skin getting accustomed to it. It also feels like my makeup is holding on so much better with this, so I use it on my T zone during the daytime. There are times when it feels warm on my skin, and times when it doesn't. When I use this, I feel like the vitamins are permeating into my skin, making it healthier.

Acne scars and nasal pores have always botherd me, so I started using this. I feel the warmth when I put it on my palms and rub them together and cover my face with it. It is comfortable to use. But the main point is that my acne scars have certainly faded! I will keep using it for a while.

I've fallen in love with b.glen starting with C Serum. I can feel this being absorbed into my skin when I feel the warmth after applying and covering my face with my hands. My skin used to break out when I was tired, but it hasn't since I started using this consistently. I will continue using this forever!

I used to have tendency for acne and redness due to hormones and lifestyle habits, but ever since I've started using b.glen products, I don't need worry. I've been complimented for my clear skin. C serum is truly effective for acne and I know that it permeates into my skin due to it warming up after application. I recommend this for those who are concerned with acne.
How to Use
Recommended Usage: slightly bigger than a dime coin (2cm/0.8 inch diameter)
Place a slightly bigger than a dime coin (2cm/0.8 inch diameter) amount of C Serum onto fingertips.
Gently pat serum onto the skin using caution in delicate areas such as the undereye and around the mouth.
If using serum during the day, be sure to follow use with SPF.
*For dry skin and/or sensitive skin, please test and observe condition first in small amounts on skin.
FAQ
Frequently Asked Questions
Using C Serum during the day is completely safe. However, the skin becomes more sensitive to sun exposure, so be sure to follow use with an SPF.
A slight warming sensation is normal when C Serum is initially applied. Vitamin C naturally has a low PH, and whe it meets with the outer layer of skin, your skin may respond with a mild warming or tingling sensation.
Both products will effectively brighten your complexion. C Serum encourages faster cell turnover, while QuSome White Essence provides protection from ultraviolet light.
