What is Vitamin C?

Vitamin C is a powerful antioxidant that can prevent or reduce damage to our cells by neutralizing the production of free radicals. To clarify, Vitamin C helps your body and skin stay healthy. It’s not a mystery that when we are kids, our parents and grandparents always tell us to drink orange juice, and the same happens when we are sick, or we feel tired. It is safe to say that Vitamin C is one of the safest and most effective nutrients.

What Are the Benefits of the Vitamin C for the Skin?

Vitamin C is fundamental for our skin because it helps collagen synthesis. If this is not that important when we are young, it’s fundamental when we age: in fact, collagen and elastin give the skin both firmness and elasticity, but their structure begins to break down when we age, meaning that we start losing firmness and elasticity.
L-ascorbic acid, aka Vitamin C, penetrates into the layer of our skin, bringing many benefits to it.

Some of these include:

• Produce Collagen Synthesis
• Protect skin from oxidative damages
• Improve the appearance of fragile and dull skin
• Prevent skin from troubles and breakouts
• Reduce inflammatory lesions
• Hydrate and moisturize skin

What to Look For in a Vitamin C Serum?

If you doubt what’s the best Korean Vitamin C Serum for you and your needs, here, you have some advice on how to choose the best and what to look for.

Formula

Most products use L-ascorbic acid, which can simply be called Ascorbic acid. It is Vitamin C in its purest form for beauty, meaning it doesn’t break easily and can be mixed with other ingredients. It’s impossible to find pure Vitamin C because its structure won’t last and will break easily when combined. Make sure you choose a water-based serum: water strengthens the power of Vitamin C and, at the same time, allows the product to be applied easily and quickly.

Other ingredients

Together with Vitamin C, it’s common to look for Vitamin E. This ingredient boosts collagen and strengthens UV protection and overall skin protection, making it the perfect ally for Vitamin C.

Size

Make sure you choose the right size: Vitamin C products tend to oxidate, meaning they lose their power after a while. Don’t go overboard, and buy a product that is good in size and that you can use for a while without problems.

How To Choose The Best Korean Vitamin C Serum

Based on all of the above, make sure you choose a Vitamin C serum with these features:

• 10-22% L-ascorbic acid
• Vitamin E
• Dark glass bottle + Airtight packaging to avoid degradation

How do I store my Vitamin C serum?

Vitamin C serums tend to oxidate when in contact with light, so it’s always better to store them in a dark place or, if you want, make sure they will last for a long time, in a fridge.

Do I have to use sunscreen with my serum?

You should always use sunscreen, no matter what else you apply to your face. In the case of Vitamin C serums, this is even more true. In fact, Vitamin C oxidizes when exposed to heat and sunlight, which means that it will not be as effective as it should be and could lead to skin damage.

Does Vitamin C have side effects?

Usually, Vitamin C is safe to use, but the reaction depends on the skin. Side effects can include stinging, redness, dryness, or yellowish discoloration.

How Do I Know When my Serum is Gone Bad?

Vitamin C serums are usually yellowish, and this is an indicator of how good they are. They must be tossed as soon as they start turning brown or orange. In some cases (like the Klairs), they can be white, meaning the turning point is yellow, indicating that your serum has gone bad.
