Klairs Freshly Juiced Vitamin C Drop is a vitamin C serum by the Korean beauty brand Klairs (also called Dear, Klairs).

Unlike conventional vitamin C serums, Klairs opts to use 5% L-ascorbic Acid. Most vitamin C serums tend to be in the 10-20% range like the SkinCeuticals C E Ferulic or Drunk Elephant C-Firma Day Serum.

For this reason, Klairs is more suitable for use as a daily vitamin C serum that won’t irritate those with sensitive skin. 

If you didn’t know already, vitamin C is great for getting rid of age spots, wrinkles and fine lines, acne scars, and hyperpigmentation. Klairs also included vitamin E in the formula, which works nicely alongside vitamin C.

This serum has a lightweight texture and is stored in a translucent dropper bottle. I’m skeptical of this packaging as most vitamin C serums are prone to oxidation (spoilage) which means an opaque bottle is usually used.

However, in this case, the company claims that thanks to “advanced Korean technology”, their formulation of vitamin C is more stable and does not require added protection.

Reviews of Klairs Freshly Juiced 5% Vitamin C have been generally positive. Many have reported signs of brighter skin, increased firmness, and more even skin tone. As always, your mileage may vary (YMMV).

The best part of this product is the super affordable price. It makes vitamin C serums accessible to those who can’t spend a fortune on high-end brands like SkinCeuticals, while still delivering a great quality product.

Klairs Freshly Juiced Vitamin C Serum Ingredients

The key ingredients in Klairs Freshly Juiced Vitamin C Serum include:

  1. 5% Vitamin C (L-ascorbic Acid)
  2. Vitamin E
  3. Centella Asiatica Extract
  4. Sodium Hyaluronate

You can find the full ingredient list here.

1. Vitamin C

Vitamin C is clinically proven to brighten skin complexion by inhibiting melanin synthesis. This helps reverse signs of hyperpigmentation such as melasma, age spots, and acne marks.

Melanin is an important pigment that determines our skin color. It also protect us from the sun’s ultraviolet (UV) radiation. 

Vitamin C promotes collagen formation. It influences gene expression (i.e. DNA) and provides essential inputs for collagen production. This helps improve the appearance of wrinkles and fine lines as well as atrophic (pitted) acne scars.

Finally, vitamin C protects our skin from the sun’s UV rays. It has antioxidant properties that prevent UV-induced free radical damage. UV rays are known causes of sunburn, dark spots, and skin cancer.

Klairs Freshly Juiced 5% Vitamin C Drop uses L-ascorbic acid. This pure form of vitamin C is the most potent type for skincare.


2. Vitamin E

Vitamin E is an antioxidant that protects skin from pollution and environmental stressors. It works synergistically with Vitamin C to protect the body from free radical damage and premature signs of aging.

In addition, studies show that vitamin C can “recycle” oxidized vitamin E to boost its antioxidant power. This means vitamin C and vitamin E are best used together for optimal results.

3. Centella Asiatica Extract

Also known as Cica, this ingredient is an herb found around the world with high antioxidant and anti-inflammatory properties. It’s earning a name for itself in many K-beauty brands as an effective anti-aging and anti-acne agent.

4. Sodium Hyaluronate

Sodium hyaluronate is a salt derivative of hyaluronic acid, a common substance in our skin. It can hold up to 1000x times its weight in water! Sodium hyaluronate improves hydration by attracting and retaining water in the deeper levels of the skin.

“Good results but terrible packaging…”

“Three stars for results: 5% is ideal for those who are new to vitamin C. With consistent nightly use, this product diminished my acne spots noticeably.
Minus 2 stars for packaging: Vitamin C rapidly breaks down in light, and needs to be in an opaque airtight bottle, in a cool place. I wasn’t able to get through half the bottle before it started oxidizing into an off-putting yellow color. The print also began rubbing off, which defeats the purpose of having instructions. Nowadays, there are many vitamin C serums/drops on the market, I recommend choosing a different brand with better packaging.”


“Faded my age spots even though it’s a mild product…”

“I’m shocked by how well and how quickly this worked. I’ve been using it for just over a month and already I can see that the two larger freckles (um, age spots) on my cheek are faded to the point that they’re barely visible. At this rate, they’ll be pretty much gone by next month, but even if they don’t get any lighter, it’s made a big difference. It does have a slightly oily feel that makes it easy to smooth into skin, but it doesn’t clog my pores or irritate my very sensitive skin. There’s just a slight warm feeling when I apply it. I usually use it before my regular night cream, waiting a few minutes between the two, and then first thing in the morning (I let it do its thing while I work out and then wash my face and moisturize afterwards). UPDATE: I used this product for a few months and then switched to one with a higher percentage of Vitamin C only to find that it didn’t work nearly as well. I’m back to using Klairs and am so impressed by the positive change I see in my skin when I use it–it’s brighter, smoother, and more even–even though it’s a mild product.”

“Low concentration vitamin C is great for beginners…”

“This is my first ever vitamin C drop. I love it and I’m thankful for what it’s currently doing to my skin. It has a very low concentration of vitamin c, so if you are hoping for an overnight miracle it might disappoint. However, if you stay consistent day and night the results will follow and you’ll be happy. I recommend using this every night. During day it depends on you because sun does play a role with how vitamin c works on your skin (it kinda lowers the effectiveness). I wear this day and night because I have heavy acne scarring, so I want to get as much help as I can morning or night. Application at night is what really matters though because that’s when you’re skin is repairing so you always want to apply at night. I started out with 1 drop, then 2, and now I use 3 drops (one on each cheek and one on my forehead). Start out easy just so your skin can get use to direct contact of the vitamin c.”
