Pure Vitamin C x Exclusive QuSome Technology


See brighter, more even skin day by day. C Serum visibly diminishes signs of aging, allowing your youthful, radiant complexion to shine through naturally. Most Vitamin C products contain unstable concentrations, which expire quickly, and have difficulty permeating through the dermal layer of skin. QuSome encapsulates the Vitamin C nutrients, allowing deeper delivery, and fast results.

Marsh

When I use this after toner, my skin feels so much healthier. My skin has become amazingly soft, it's crazy! I use this, especially when cold weather bothers me.

MikuHousewife

I feel like my pores are getting smaller! Not only did my acne get better, but my skin is now sleek. I want to keep using this product. Even I can use this, and I have a damaged skin barrier.

TomoOffice Worker

Although I can't belive it, my blemishes are disappearing. They started fading ever since I started using this product. I had blemishes on my hand as well, but they vanished as I started using this. I want to keep using this.

TKOffice Worker

My skin became softer after I put this on. I could feel the product permeate into my skin, and I feel las though my blood circulation get better. I love this because I no longer have rough skin since my consistent use of C Serum.

TKHousewife

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.

CL

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...

ExetaHousewife

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.

KT

I have used and loved this product for more than ten years. When I forget to use this, I tend to break out, so this is a neccssity. I also like how my skin gets warm when I put this on.

ME

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!

A

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...

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.
