It's great for layering multiple times when you don't use toner.
Cons
The viscosity is much more fluid than expected, so it can flow smoothly.

This product was purchased to improve skin radiance. When I first used it, I felt a slight stinging sensation on my skin, which is a natural phenomenon that can occur when using a high-concentration pure vitamin C product. This reaction is a sign that the vitamin C is working effectively on the skin, and there is generally no major problem, so you don't need to worry. However, for those with sensitive skin, it is recommended to do a patch test before use or use it in the evening. Personally, I had a brief stinging sensation, but it went away quickly, and the next morning, my skin felt a bit brighter. ✔️ Consistent use is essential! A single day's use may not yet show noticeable changes, but the expected effects are clear when used consistently. The highly concentrated vitamin C ingredients appear to be able to make the skin clear and bright. It seems to be a suitable product for those who want to improve dull skin tone, blemishes, and freckles. Vitamin C has the effect of inhibiting melanin formation, helping to prevent pigmentation caused by UV rays and brighten existing dark areas. After using it consistently for about 2 months, my blemishes and freckles have faded.
Cons
✔️Irritation: Pure vitamin C can cause skin irritation when used at high concentrations. Especially for sensitive skin, symptoms such as stinging, redness, and dryness may appear. Therefore, it is recommended to perform a patch test before use. ✔️Oxidation: Vitamin C is easily oxidized when exposed to air, light, and heat, which can reduce its effectiveness. Therefore, it is best to store it in an airtight container and keep it in a dark place. ✔️Prompt Usage: Pure vitamin C serum is easily oxidized, so it is best to use it within a certain period after opening. Most products provide guidance on the usage period, so it is important to refer to this.
Tip
Please be careful with storage! Refrigeration is essential. Discolored vitamins are ineffective.

There are pigmentation marks on my cheeks, and they have faded a bit after using it. The amount is generous, and the bottle is brown, indicating good oxidation prevention. It's been about two months since I purchased it, and while it has become slightly yellowish, there hasn't been a significant change. It's pure vitamin C, and it's not irritating. I'm quite sensitive to fragrances, but this product has little to no scent.
Cons
Due to the nature of vitamin C, there is a sense of it not being fully absorbed, almost as if it's not being absorbed like oil.
Tip
Respected intellectuals are recommended to blot excess oil with blotting paper after application. Using a mild acidic cleanser followed by vitamin C can enhance absorption.

When I wake up, I feel like my skin is well-organized, and the redness has subsided.
Cons
There are no particular downsides, but when I have skin troubles, it stings a bit... There is some irritation.

The fluid texture flows smoothly and is well-absorbed with good spreadability. The ingredients are gentle, so there's no need to worry about breakouts. I recommend purchasing the product that suits your specific needs. I also like that it's fragrance-free.
Cons
Since this is an essence, you can't just use it alone. You'll need to apply it along with other products. It can be a bit drying, you know.
Tip
Layering it on twice or so works well.

This serum is the ultimate cost-effective vitamin C serum. I also purchased it based on a YouTuber's recommendation and used it in sequence from VM to VA. Definitely, there was no irritation at all when using VM, but there was a slight irritation when I first applied VA. However, after a few days of use, my face starts to glow. I was someone who had acne scars, and I didn't know what the whitening effect was, but this serum has made me realize what the whitening effect is. It not only enhances the skin tone but is also highly recommended for those with severe acne scars like me.
Cons
None!! The price is affordable, the amount is sufficient, and it's good. The only thing is that you need to pay a little attention to the storage method~? You should wrap it in aluminum foil and store it in the refrigerator. Also, it should be used up within 6 months!!
Tip
In the morning, apply the vitamin serum, and in the evening, apply retinol or TN serum - this is the best combination! I'm using the Insta Natural Retinol 2.5% and the Cosrx TN Serum products!

It's a non-irritating, moisturizing serum. It's a good starting point for vitamin C.
Cons
There doesn't seem to be any downside. I'm using it with satisfaction.
