It can be a bit irritating, so be cautious when using it if your skin is in poor condition. You might experience some tingling sensation.

When I use this as part of my nighttime skincare routine, the results the next morning are truly amazing. My skin feels absolutely radiant. I can't live without this product!

VA 순수 비타민 씨 C 15 세럼

The consistency is thinner than expected, so it might run down your face

It's great for layering multiple times when you're not using a toner

The absorption isn't particularly impressive, and there's a slight scent to it.

While it doesn't dramatically brighten the face, there is a subtle improvement in the complexion.

✔️Be careful with storage!
Refrigeration is a must. Discolored vitamin C loses its effectiveness, unfortunately.

✔️Irritation: Pure vitamin C can irritate the skin at high concentrations. Those with super sensitive skin may experience tingling, redness, or dryness. It's advisable to do a patch test before use.

✔️Oxidation: Vitamin C can easily oxidize when exposed to air, light, and heat, reducing its effectiveness. It's best to store it in an airtight container in a dark place.

✔️Quick use: Pure vitamin C serums are prone to oxidation, so it's best to use them within a certain period after opening. Most products provide guidelines on usage duration, which is important to follow.

I purchased this product because I needed antioxidant benefits for my skin.

When I first used it, I felt a slight tingling sensation on my skin. I understand this is a normal reaction when using high-concentration pure vitamin C products. This response is actually a sign that the vitamin C is working effectively on your skin, so there's generally no need to worry. However, if you have sensitive skin, I recommend doing a patch test before use or applying it in the evening. Personally, I experienced a brief tingling sensation, but it quickly subsided, and the next morning my skin seemed clearer.

✔️ Consistent use is key!
While you might not notice significant changes after just one day, the expected benefits from consistent use are clear. The high concentration of vitamin C appears capable of making your skin brighter and more radiant. I think this product is particularly suitable for those looking to improve dull complexion, blemishes, or dark spots. Vitamin C is known to inhibit melanin formation, helping prevent sun-induced pigmentation and lightening existing dark areas. After about two months of regular use, I noticed my blemishes and dark spots had faded.

For those with oily skin, I recommend blotting excess oil with oil-absorbing sheets after letting it absorb. Using this vitamin C serum after cleansing with a slightly acidic cleanser can improve absorption.

Whether it's due to the nature of vitamin C or not, it feels like it sits on top of the skin. It's as if it doesn't absorb well, almost like an oil.

The dark spots on my cheeks have slightly faded after using this. The quantity is generous, and the brown bottle helps prevent oxidation. After two months, it's only turned slightly yellowish without major changes. Despite being pure vitamin C, it doesn't irritate my skin. As someone sensitive to fragrances, I appreciate that it's nearly scentless.

There's not much to complain about, except that it can cause a slight tingling sensation when you have blemishes. It might be a bit irritating for sensitive skin.

When I wake up, my skin feels more balanced and I notice a reduction in redness. It's like it works hard while I sleep!

I found it works best when you layer it twice.

Since it's an essence, you can't use this alone. You need to apply it with other products. It can be quite drying on its own.

The runny texture absorbs well and applies smoothly. With its gentle ingredients, it's no surprise there are no blemishes. I think you can purchase it based on the specific functions you need. I also like that it's fragrance-free!

For the best skincare routine, apply vitamin serum in the morning and use either retinol or TN serum in the evening. Personally, I use Instanatural 2.5% Retinol and Cos De BAHA for my TN serum!

There are no downsides! The price is reasonable, and the quantity is sufficient. Just keep in mind the storage method - wrap it in aluminum foil and refrigerate. Also, remember to use it within 6 months!

This vitamin C serum is the ultimate bang for your buck. I bought it after a YouTuber's recommendation and used VM then VA in sequence. With VM, I felt no irritation at all, while VA had a slight tingle when first applied. However, after a few days of use, your face literally glows. As someone who had acne scars, I never really understood what 'brightening effect' meant until this serum showed me. It not only significantly improves your complexion but I especially recommend it for those with severe acne scarring like myself.

The only downside is that it might be a bit too strong for some people's skin.

Great value for money! I love how concentrated it is - I haven't found a better alternative yet.

I can't think of any downsides. I'm using it with complete satisfaction.

It's a gentle, hydrating serum that's perfect for those new to vitamin C products.

There's nothing particularly disappointing about it. It's just quite rich, so it might be a bit too oily for those with oily skin.

I'm still not quite sure about it. I've been using it because I heard vitamin C is good for acne scars. Not certain if it's working, but I'm sticking with it for now.
