For optimal absorption of brightening ingredients, apply immediately after toner. If you have dehydrated skin, be sure to follow up with a moisturizing cream to prevent any feeling of tightness. Using it in the morning can help reduce skin dullness, making it great to use before applying base makeup.

For a high-concentration niacinamide product, the brightening effects aren't particularly rapid. It doesn't significantly help with oil and moisture balance, so you'll need to rely on other products for hydration. The glass bottle has a slightly loose cap, which may cause the contents to dry out easily.

Among brightening serums, this one is lightweight and gentle, making it suitable even for sensitive skin days. Upon application, it gives a sense of immediate skin refinement. Despite containing 10% niacinamide, it doesn't feel harsh, allowing for trouble-free use. Rather than dramatic improvements in tone correction or blemish reduction, it subtly reduces overall skin dullness. Its non-sticky texture makes it perfect for morning routines. It's a solid choice when you want to refine your skin, especially if you're aiming to improve both texture and complexion simultaneously.

15% 순수 비타민C E 페룰릭 애씨드 세럼

Use it generously... before it oxidizes...

I bought three bottles, but it stings when applied due to its acidity. I only managed to use one bottle and had to sell the rest on a secondhand app. It's really challenging to use consistently enough to see whitening effects. The tingling sensation makes it difficult to apply confidently each time.

A pure Vitamin C ampoule at a reasonable price! I bought it because I heard it has a similar formulation to SkinCeuticals. While the unique scent of the ingredients can be a bit metallic, it's still tolerable.

It's said that after cleansing with a low pH cleanser and applying toner, the vitamin C absorbs even better.

Among pure vitamin C products, it's reasonably priced and the product is quite good. There's not really anything to complain about. I hope they continue selling it.

The texture flows like water with a hint of oil. It has a distinct vitamin C scent. When applied, there's a slight oily feeling that absorbs to leave a moisturized sensation. I'm on my third bottle now. It's affordable and seems to have brightened my complexion by a shade.

I didn't experience any downsides. I'll likely repurchase it. Highly recommended!

While using vitamin C serums, I always wondered if they were actually effective. But with this product, it's the first time I've truly felt the benefits of vitamin C. I was also impressed by how thoughtfully they designed the packaging, considering the product's volume and potential oxidation.

The scent is a bit unpleasant. It smells somewhat like garlic, I think.

I bought this after watching YouTuber Jeyna's video. After using it for about 3 days, I could feel my skin texture improving!

Since vitamin C is said to be beneficial when used in the morning, I applied it in this order: [toner - vitamin C - moisturizer - sunscreen]. When using it in the morning, sunscreen is absolutely essential! Vitamin C can lose its effectiveness when exposed to light, so you must apply sunscreen. It's recommended to wait about 3 minutes after applying vitamin C to allow for skin absorption.

I was mainly hoping for brightening effects, but I didn't notice any after two months of use...

Vitamin C products often come with a hefty price tag, but this innovative concept's incredible value for money is its biggest advantage. I've used it almost daily for two months without any tingling or blemishes. I could see my skin barrier strengthening and my complexion improving. It absorbs well, and there's a very subtle fishy scent, but it's not bothersome.

Pro tip: Wait 1-2 minutes after application for the product to absorb. This prevents makeup from pilling and allows the active ingredients to penetrate the skin more effectively for better results.

No complaints so far. The price is reasonable, and I'm happy with the ingredients.

Skin type: Dry/Sensitive/Thin with redness/Prone to small blemishes/Losing elasticity

As someone with super sensitive skin, I was cautious about using Vitamin C. After careful consideration, I started with the 15% formula. The results? I'm absolutely thrilled! My complexion seems clearer, and the best part is how my skin feels after application - it's like it's been given a boost of firmness and radiance before makeup. Plus, there's no pilling with my foundation.

Sometimes it can cause itching when applied to areas with thin skin, like the neck.

My skin has definitely improved after using this. It's smoother and the effects are noticeable.

For those with super sensitive skin... be cautious with active ingredients, especially high-concentration vitamin C serums and retinol! My one-line review for this product is: 'Save money, gain blemishes'.

1. Every time I use this, my skin breaks out... Seems like there's an ingredient that doesn't agree with me. I'll definitely never apply it again.

1. Compared to other vitamin C serums, this one offers great value for money! You can purchase a bottle for around $15, including shipping costs.

After using the powder form for so long, the amount in this liquid version seems a bit small.

I've been using vitamin C in powder form, but this is my first time trying it in liquid form. I only use it in the morning and always make sure to apply sunscreen afterwards.

The storage instructions emphasize refrigeration, and they recommend using it before it discolors. The brown bottle should help prevent discoloration.

The dropper format allowed for hygienic use. I mixed it with my essence. Since I've been consistently using vitamin C, I didn't experience any tingling. Unlike the powder form, which needed to be dissolved and could feel gritty if not fully dissolved, this liquid form was much more comfortable to use.

Looks like I'll be sticking with the liquid form from now on!

It's quite cost-effective. Since it's important to protect the skin throughout the day, I'm diligent about applying it. I don't use it together with retinol.

So far, I don't have any disappointments. Please don't raise the price!

I used to use Vitamin C from Physiogel, which worked well, but I wanted to see more dramatic results. So I switched to this innovative concept with a higher vitamin content. As expected, due to the higher concentration, it tingles and itches a bit, but without any visible side effects. My skin texture seems to be getting smoother and brighter. Although it's watery and I didn't expect much hydration, it does provide some moisture. It feels quite refreshing. I'm satisfied with the price point too, so I don't have any complaints. They say it's best to use vitamin products within a month of opening, so the amount seems just right. If I don't experience any adverse reactions, I plan to stick with this for a while.
