Vitamin C

I'm sure everyone knows that vitamin C is good for us. Vitamin C is one of the most effective nutrients for our skin.

Let's start with its main effects.

When free radicals, caused by internal/external stress, accumulate as activated oxygen in our body, it disrupts healthy skin cells and causes aging. However, the core function of vitamin C is to eliminate these toxic free radicals and prevent skin aging.

When our skin is exposed to UV, the melanin cell deep within our skin produces melanin pigment, causing discoloration such as freckles and spots. Vitamin C blocks this pathway of melanin pigmentation, ultimately improving skin tone.

Vitamin C is one of the core elements in forming collagen, an essential part of our skin. And if we lack vitamin C, collagen synthesis decreases and the skin loses elasticity.

Therefore, vitamin C is an ingredient that replenishes collagen, which improves elasticity and wrinkles.

Properties of vitamin C

Pure vitamin C is volatile and is easily oxidized by various factors such as air exposure, UV exposure, pH and temperature. As oxidation progresses, it takes on a dark yellow color, which can even turn brown when it increases too much.

Despite its instability, vitamin C is still the most beloved ingredient due to its excellent skin effects. And to control pure vitamin C, various vitamin C derivatives have been developed and are actively used. Vitamin C derivatives are well known to be good for our skin, as specific chemical reactions and enzymatic actions convert them into pure vitamin C. However, it is an early stage to be sure that vitamin C derivatives have the same effect as pure vitamin C, as it needs to be clarified how it is converted and how much it does.

Therefore, pure vitamin C, ascorbic acid, is the most recommended ingredient to achieve the right effect.

Pure vitamin C is excellently absorbed by the skin, and a study shows that the amount of vitamin C increases in a short time due to this reason.

We can also expect better effects when used regularly than just once, as it will preserve the vitamin C in our skin.

To support the effect of a vitamin C product, optimal pH should be used, taking into account not only the vitamin C content, but also the skin's absorption rate and stability.

Studies have shown that ascorbic acid is better absorbed by the skin when the pH ratio is stronger.

However, products with strong acids are not recommended under pH conditions as they can irritate normal skin, which is slightly acidic.

Considering the nature of vitamin C and our skin, the best pH condition for a vitamin C skin care product is approximately pH 3.0-4.5.

Vitamin C product guide

Storing products with a high content of pure vitamin C in the refrigerator is the best way to keep the vitamin C fresh. It is also strongly recommended to close the lid (dropper) after using the product and keep it away from high temperatures or direct sunlight. It is best to finish using the product before the expiration date after first opening.

*Using sunscreen together enhances the effect when you use the vitamin C product during the day.

Depending on your skin type, you may feel slight dryness or skin tightness after using the Vitamin C product. Using a hydrating/moisturizing cream together will help balance the finish.

Start your healthy skin care routine by using vitamin C cosmetic products.
