Pros

First, I was satisfied with the capacity at this price.🙂 Since the price was reasonable for me, I was drawn to this product and decided to purchase it. When I tested it on the back of my hand, I first smelled the fragrance, and it had a refreshing citrus scent.😍🫣 I really liked the refreshing fragrance, which is my favorite. Since the other creams or serums I'm currently using are unscented, I felt the fragrance of this product was quite distinctive and I really enjoyed it. And the application was not too quickly absorbed, but had a lingering feel on the skin.~~ The texture was not too heavy, but not too watery either, with a slightly oily feel.🫠 Since it's not heavy, I think it will be great to use in the summer. Although I've only been using it for about 3 days and left this review, I'm not sure about the whitening effects yet, but I feel it's doing a good job of maintaining moisture without causing any facial issues. I think I will continue using it until the end.😗

Cons

There are no troubles, and it's a whitening product, but it also has good moisture, so I couldn't find any downsides.

Tip

Before moving on from the basic skincare routine to the serum, I first spray on a mist. Then I dry my hair and proceed to the serum step of the routine. This helps prevent my makeup from creasing or wearing off, which is great.

Pros

Application: Good Absorption: Excellent Recommended skin type: All skin types I've been using this product morning and night for 5 days, from April 30, 2025, to May 4. It comes with a dropper, and although the formula is thin, it doesn't run excessively. With a 60ml volume, I feel I can use it for a long time without worry. My skin texture has become incredibly smooth. I'm not sure if my complexion has noticeably brightened yet, but I definitely noticed an improvement in skin texture within a day or two. I think I need to use it consistently for about another week. You know how important it is to apply vitamin C regularly, right? I highly recommend this product!!!

Cons

The price is a tiiiny bit high for the amount you get. But since it's effective, I'll likely continue using it.

Tip

I found it works even better when applied after essence or serum, rather than immediately after toner in your morning and evening skincare routine.

Pros

■ Absorbs well The ampoule's texture is lightweight and spreads smoothly, effortlessly sinking into the skin without rubbing. While not watery, it's almost non-sticky, making application comfortable. A small amount covers the entire face evenly, resulting in a satisfying user experience. ■ Absorption It leaves no residue on the skin, finishing cleanly. After absorption, it maintains long-lasting hydration without deep dryness. Particularly suitable as a daily product, as it doesn't cause pilling even when used before makeup in the morning. ■ Recommended Skin Types Combination/Oily Skin: Thanks to its fresh finish, it seems suitable for use on skin with excess oil without feeling heavy.

Cons

Due to the nature of vitamin products, there's a risk of oxidation when exposed to air.

I love how it's not sticky and feels so clean. It's perfect for daily use!

Pros

(Review after using the product won from the Hwahae Testers) This was my first time trying a skincare product with vitamin C, and I think it's a great option for beginners. First off, the scent when I opened the product was so pleasant that it made me want to use it consistently. When applied, there's no irritation - it goes on smoothly and absorbs well. After application, my skin feels soft and velvety to the touch. I saw noticeable effects in calming redness.

Cons

I think most people expect vitamin serums to brighten their complexion, but I didn't see much improvement in that area.

Tip

When used together with a regenerating cream, I noticed enhanced effects in calming redness and quickly soothing my skin.

Pros

I bought this after a friend recommended it, and I'm so glad I did! Even for my dry skin, it was wonderfully hydrating and absorbed quickly without any stickiness. The scent is a delightful blend of yuzu and lemon, giving it a vitamin C-rich vibe that made me trust it even more. It didn't cause any significant irritation, so it seems suitable for all skin types!

Cons

There weren't many downsides to speak of. However, if you have extremely dry skin, using this alone might not be enough. I'd suggest pairing it with a cream or emulsion for best results!

Tip

Personally, I apply this ampoule generously after using Riddle Shot, then finish with a wrapping mask. This method allows the beneficial ingredients of the vitamin ampoule to fully penetrate the skin, effectively brightening and hydrating. If you don't have sensitive skin that reacts to Riddle Shot, I highly recommend trying this routine!

Pros

I got the chance to try Twenty Key's Vitamin Ampoule through a survey panel win! Though there was no obligation to review, I'm voluntarily sharing my thoughts because it's so lightweight and pleasant to use. The formula is light, making it perfect for summer use. Unlike some other vitamin serums, it doesn't cause any irritation, so it's gentle and easy to incorporate into your routine. I'm almost finished with it now, and I've noticed it's helped improve my complexion too!

Cons

I'd recommend this for summer due to its lightweight feel. It might feel a bit too light in winter, but layering it with a cream should solve that issue.

Pros

I received this product as a winner of The Hwahae Testers program from January 10th to 17th. I've never purchased a vitamin ampoule separately before, but after trying it this time, I noticed my face definitely seemed a bit brighter. The amount is quite generous, so I've continued using it even after the review period, and I'm loving it! What I appreciate most is how it hydrates and brightens my complexion.

Cons

There's nothing I dislike about this product! I didn't experience any blemishes either!
