Best Vitamin C Serum In Korea – FAQ
If you still have some doubts and insecurities, no worries. I will answer you some of the most frequently asked questions, that may bother you, especially those related to safety of your vitamin C serums.
What Is Vitamin C Serum & What Are Its Benefits?
Vitamin C, also known as ascorbic acid, is nowadays one of the most popular ingredients in various skincare lines. It is a holy grail for various skin concerns, improving your skin’s condition overall – and all of it is – scientifically proven!
Vitamin C has skin brightening properties, meaning it will fade any discoloration (including acne scars).
Also, it helps you slow down skin aging, as it boosts collagen production, improving skin elasticity and reducing fine lines and wrinkles.
It also prevents collagen to break down faster, thanks to its antioxidant benefits and blocking of (bad) reactive oxygen species.
Due to vitamin C’s anti-inflammatory properties, it can help reduce the redness and irritation that comes with acne breakouts, too.
Besides all of that, vitamin C minimizes the redness you can get from sun exposure and sun damage. Using vitamin C serums before sunscreen aids UV protection and protects your skin better, making it a great combo.
What Are The Drawbacks Of Vitamin C (L-Ascorbic Acid) Serum In Skincare?
Well, as with any skincare product – vitamin C products also have some drawbacks.
First of all, vitamin C is unstable. Exposing it to high temperatures, air, and sunlight can cause it to oxidize. And once it oxidizes, it becomes pretty much – useless.
It can also react with other skincare ingredients, with the potential of developing skin irritation. This primarily refers to exfoliators, including AHA/BHA.
Keep in mind that high concentration, higher than 10% can irritate your skin.
Therefore, if you’re introducing it to your skincare routine, make sure you start with lower concentrations.
Which Form Of Vitamin C Is Best For My Skin?
Derivatives of vitamin C in the skincare industry are safe and effective.
Probably the best way to introduce it into your routine is – using it as an active ingredient in your serum.
When Is The Best Time To Use Vitamin C Serums?
You can use your serum everyday. You can use it maximally twice a day (in the morning and evening). However, in any case, for the best results, use it before a sunscreen before you head out.
Can I Use Vitamin C Serum On My Face Every Day?
Absolutely! However, I would highly recommend you start with low concentrations of vitamin C and then slowly increase as your skin becomes used to it.
Also, if you have sensitive skin types, rather use it 2-3 times a week.
Why Do Vitamin C Serums Change Color Over Time?
Vitamin C oxidizes when exposed to heat, air, sunlight. It is a normal reaction of vitamin C. So, when your serum changes color – it is due to vitamin C.
You can notice that your serum becomes more yellow, orange, or brown in color. And, it is expectable.
Can I Still Use Vitamin C Serum If It Turns Brown Or Orange?
Although, probably, nothing bad will happen (unless you have extra sensitive skin), I wouldn’t recommend you to use it. Once it oxidizes, it is much less effective, or even ineffective.
So, you will not get the benefits from it. Try to use vitamin C serums within 6 months of purchase or opening.
How To Prolong Shelf Life Of My Vitamin C Serum?
To avoid oxidation, and to prolong its shelf life, store your vitamin C serums in a cool, dark place, away from the direct sunlight.
Skincare organizer for your fridge is great solution.
