You’ve probably heard of Klairs Freshly Juiced Vitamin C Serum. It’s talked about a lot in the kbeauty community, so I knew I had to try this one out. It’s recommended to be used together with the Klairs Freshly Juiced Vitamin E Mask for better results, but I still haven’t got my hands on it yet.


Designed with naturally effective ingredients that are safe and non-irritating, the Freshly Juiced Vitamin Drop energizes and rejuvenates your skin with the power of pure Vitamin C! Containing key ingredients directly from nature and concentrated pure Vitamin C, this innovative multi-solution, non-irritating formula revitalizes, maintains, and transforms your skin! No need to stress over dull skin tone and enlarged pores anymore.

The Serum contains Vitamin C at a concentration of 5% and a pH level of 3.81.

Vitamin C

Vitamin C (known as ascorbic acid) is a water-soluble vitamin that has multiple skin benefits: protects the skin from UV damage, inhibits melanin formation – corrects hyperpigmentation, brightens and evens out the skin tone. It also promotes the growth of collagen ( a protein that provides structure and elasticity to the skin). However, it takes time and consistent application to see the best results.

How to Store

Vitamin C has a short shelf life because it is water-soluble and breaks down when it’s exposed to oxygen. It’s not easy to formulate and maintain its effectiveness once the bottle has been opened. Heat and humidity can ruin your Vitamin C serum. Hence, to extend the product’s life, it needs to be stored properly: in a cool place away from direct sunlight.

My serum got a slightly yellowish tint after some time, so now I store it in the fridge.
*Discontinue use if your Vitamin C has turned completely yellow or brown!


Apply about 2-3 drops on the face, after cleansing with a low pH cleanser. Those with very sensitive skin can go with the serum after you’ve applied your balancing toner to avoid irritation.

Vitamin C is acidic, so if you’re using it for the first time, use it every other day and gradually increase to daily applications. This will help ease tolerability.

VERY IMPORTANT: You should follow up with sunscreen when using it during the day!

In addition, if you’re incorporating other active ingredients in your routine, please refer to my post: How to Layer your Skincare and active ingredients.


Klairs Freshly Juiced Vitamin C has an oil-like consistency and it needs some time for the skin to absorb it. It is lightweight though. The finish is very smooth and not sticky at all.


For those of us with oily skin it can be a little difficult to apply sunscreen or makeup on top without getting greasy after a few hours.
Using an antioxidant such as vitamin C under sunscreen, it can protect the skin from further photo damage caused by UV rays. Therefore, they make a powerful combo. However, because of my oily skin I prefer to use it during the night.
Dry skin types will probably not have any problem using it as a day serum.

I feel a slight tingling and warmth while the product soaks in. And this is normal. I have only experienced stinging and a bit of redness when my skin has been oversensitive, for example when I have used an AHA the night before. This is a reminder, to not be too harsh on the skin with actives and try to find a balance. Sometimes you can be using too much and overwhelming your skin.

The first 2 times that I used this I got 2-3 pimples, but after that my skin adjusted and I’ve had no breakouts at all.
I’ve used this serum consistently for more than a month, and as with most actives, it takes some time until you start noticing some results.
There has certainly been improvement on overall texture. The skin feels much smoother.
When I use it during the night, the next day my complexion appears brighter. Moreover, I’ve noticed my acne spots fading faster than usual.
Regarding sun spots, there hasn’t been any noticeable change yet.


Klairs Freshly Juiced Vitamin C Drop Ingredients

Final Verdict


  • Brightens.
  • Evens out the complexion.
  • Improves skin texture.
  • Smooth finish (not sticky)
  • Slight fading of acne spots.
  • Cruelty-free
  • Suitable for all skin types.


  • Doesn’t work well under sunscreen/makeup for oily skin.

With active ingredients, to be able to see results in terms of anti-ageing effects, improving elasticity or correcting hyperpigmentation, I personally think that you have to use them consistently over a long period of time. This is a great Vitamin C serum to start with, if you don’t have a lot of experience with actives. Brightens, improves skin texture, fades acne spots faster. Vitamin C is a great antioxidant and this one is gentle, yet effective. I would repurchase.

Important advice: Patch test any product before fully applying it on the skin, especially if it’s an active ingredient.
