What’s vitamin C and why is it important to use one in your skincare routine
Vitamin C is an antioxidant that plays a crucial role in skincare. It helps to protect the skin from damage caused by free radicals, which are unstable molecules that can lead to premature aging and skin issues. Vitamin C also aids in collagen production, promoting skin elasticity and reducing the appearance of fine lines and wrinkles. It can help brighten the skin by reducing hyperpigmentation and uneven skin tone.

The serum comes in a transparent 35 ml plastic bottle with a dropper. I was shocked at first because most vitamin C serums come in an opaque bottle to protect the serum from oxidation but according to Wishtrend, the serum is stabilized which is why it can be kept in a transparent bottle.
The scent doesn’t have any noticeable scent so I guess I can say it’s fragrance free.
It has a light consistency and kind of feels like an oil when you apply it. I personally don’t have any problem with this consistency because it glides across my face easily and it’s fast adsorbing too.
When I first started using this vitamin C serum, it caused me to purge.
What is Purging?
Purging in skincare refers to a temporary breakout period that can occur when using active ingredients. It’s caused by faster cell turnover, bringing underlying impurities to the surface. It usually lasts a few weeks and is normal.
Once the purging period was over, I was super impressed with the results. My skin was brighter and I noticed my hyperpigmentation and dark spots were fading and overall, my skin was looking brighter and healthier. I was using Dr. Rashel’s vitamin C serum before this and unfortunately, I didn’t see the results I was hoping for but with the vitamin C serum, everything changed.
I use it during my morning skincare routine only because vitamin C serums should only be applied in the morning after using a hydrating toner (I’m currently obsessed with the Im from Rice toner and the Hada Labo Shirojyun lotion). Once it hits your skin, it feels warm and oily but it disappears once you rub it into your skin.
When I started using the klairs vitamin C serum, I had a few active breakouts and this helped me so much to get rid of them and I noticed that it didn’t leave a dark spot like it normally would. It has a low percentage of vitamin C and I think it’s a great Korean vitamin C serum for beginners and those with sensitive skin.
Did I mention that a little goes a long way? I have been using mine for weeks now and I haven’t even used up to a quarter of the bottle. A bottle will probably last you 3-4 months. Just make sure you keep it in a dark cool place like a skincare fridge if you have one to increase the shelf life of the product.
Do I think the klairs vitamin C serum is worth the hype? Absolutely yes! I love it so much that I had to add it to my list of the best Korean vitamin C serums. It works, is affordable, helped my hyperpigmentation so much, and gave my skin a healthy glow.
