Review: Klairs Vitamin C Serum

Review: Klairs Vitamin C Serum

We all grew up knowing Vitamin C is great for colds. But what if I told you Vitamin C is also fantastic for your skin (and big in Korean skin care)? Believe me, the benefits are just too many to miss out on. Studies have shown vitamin C is effective against wrinkles, inflammation, and dark spots - basically half of the world’s skin concerns, right? Vitamin C (ascorbic acid) is an anti-oxidant, meaning it stimulates natural collagen production. In addition, it limits the production of free radicals, thereby speeding up the your skin's healing process, and reduces melanin production and oxidation. In fact, vitamin C is a natural component of our skin, but aging, UV exposure, and pollution lower its concentration, damaging our overall skin health. This is why you need to replenish your vitamin C supply through food and cosmetics. The solution I propose is: 1. become a smoothie-goddess today and 2. add the Klairs Freshly Juiced Vitamin C in your beauty routine tonight.

Klairs Vitamin C serum has a safe concentration of this wonder anti-oxidant in its purest form (5% L-ascorbic acid). That’s because a high concentration of Vitamin C is also sensitizing. With 5% of L-Ascorbic Acid, this oil type serum is just enough to give you all the benefits without any of the risks. The formula includes centella asiatica and numerous botanical extracts (e.g. lavender, anise, broccoli, grapefruit, etc.), making this an oil-serum with extra soothing and nourishing properties. When developing this serum, Klairs made sure vitamin C was stabilized, as the ingredient might have a short shelf life otherwise. Still, make sure to store it away from light, ok? I keep mine in a drawer, just to be sure.

Klairs Freshly Juiced Vitamin C Serum Honeysu Korean Cosmetics Europe

This product is great for:

  • all skin types
  • fighting acne scars (Post Inflammatory Hyperpigmentation - PIH)
  • reducing and preventing wrinkles and fine lines
  • evening out skin tone
  • simplifying your skin care routine (multiple results with one single product)

This product is not for you if:

  • your skin is extremely sensitive
  • you have rosacea or other form of permanent redness
  • you won't wear sunscreen the day after


There are two ways to include this serum in your skin care routine. For faster results, apply 3-4 drops directly onto your face or use it as a spot-treatment. I recommend the gradual introduction of this serum if you haven’t used vitamin C before, the reason why I love to mix 2-3 drops with my favorite moisturizer. At first, the serum causes a tingling sensation, which quickly fades. Oily skin types don't have to fear the word "oil" in here. The product is easily absorbed and doesn't clog pores or leaves a greasy feeling behind.
