  Pros

  A review after finishing a whole bottle! If you want to improve your skin texture and complexion, use this! Two years ago, I had oily skin and combination dehydrated skin in my T-zone, always full of tiny bumps. After using this vitamin powder, I've seen a lot of improvement! When I first tried it, I thought, 'This is amazing!' I meant to use it for a long time and leave a good review, but I forgot until now. It's said to have pore-tightening and anti-inflammatory effects, so I often used it after extracting blackheads and sebum! After mixing it with toner or aloe gel and applying a thin layer, you can gradually feel your skin tightening. I usually waited 3-5 minutes, feeling the pores contract, before continuing with the rest of my skincare routine. After doing this, I rarely experienced contact dermatitis or blemishes after extractions. It seems to have a disinfecting effect, though it can sting a bit on cuts or peeling skin. Due to the product's nature, it becomes watery after mixing. Be careful not to spill it! This product is sensitive to UV rays. Only use it at night or apply sunscreen thoroughly. It's said to work well with propolis and vitamin E oil. As I have combination dehydrated skin, propolis felt a bit heavy for me. Mixing it with a hyaluronic acid ampoule and a drop of vitamin oil worked best for me.

  Cons

  The product oxidizes and turns brown if left for a long time after use. I applied the leftover product on my neck and forgot about it before going out... It left a dirt-like residue on my neck! There's nothing disappointing about the product itself though.

  Tip

  Try using it as a skin pack by mixing it with aloe gel and applying it with a cotton pad! Mixing it with a hyaluronic acid ampoule worked best for me.

  Pros

  After two weeks of use, I haven't seen dramatic effects yet. In the morning, after cleansing, I take a pea-sized amount on my palm, mix it with Onething's Niacinamide, apply it, then follow with a vitamin C and E combination. I finish with Manyo Factory's Galactomy Essence Cream and make sure to thoroughly apply sunscreen. I'll keep using it consistently and write a second review after repurchasing. As I have super sensitive skin, I started with a tiny amount for the first few days. During this transition period, I definitely felt some irritation and slight redness on my skin.

  Cons

  Even when I applied a very small amount at first, my face still experienced a burning sensation and slight redness. After a few days of adjustment, it's fine now.

  Tip

  I'm currently diluting this product by mixing a pea-sized amount with Onething's 10% Niacinamide Toner before applying.

  Pros

  This vitamin C powder is a direct hit for brightening! I'm so satisfied that I even recommended it to my younger cousin. It works even better when used with galvanic devices.

  Cons

  The mixing ratio can be a bit tricky. If you mix in too much, it can cause irritation and redness.

  Tip

  If you're using it for the first time, I'd suggest applying it every other day to start.

  Pros

  I bought this for pigmentation and brightening purposes. It's so convenient to mix with my regular essence or emulsion cream - just a dab here and there does the trick!

  Cons

  If you use it for a long time, your skin might become a bit sensitive, so you may need to take a break from it occasionally.

  Tip

  Remember to mix only a small amount!

  Pros

  It definitely nourishes the skin, making it noticeably brighter. This is a great product.

  Cons

  I'm not sure if it's incompatible with the serum I'm currently using, but when I mix them together and apply, it smells like iron and turns my skin red. I don't know exactly what causes this reaction, but it makes it difficult for me to repurchase.

  It gives my skin a beautiful glow. I mixed it with essence for application.

  Pros

  I bought this because it's vitamin C, which should be good for the skin. It doesn't have any harmful ingredients and it's pure vitamin powder.

  Cons

  If you apply even a little too much of this, you get blemishes. Every time I use it, I wake up the next day with breakouts. It's so scary that I haven't been able to use it for two months. Such a waste... I'm thinking of using it on my body instead, but I'm too lazy to bother.

  Pros

  First off, I loved the sensation of the tiny granules (vitamin C) directly touching my face. It really gave me that 'Wow, I'm actually using vitamin C!' feeling.

  Cons

  Unfortunately, I experienced some blemishes. My skin isn't usually super sensitive, so I think I might have used too much product.

  Tip

  When using this, try applying just a small amount rather than slathering it on. Using too much can lead to blemishes.

  I mix a little bit of this with my skin emulsion, and my skin texture has really improved! It also has a brightening effect, and I'm expecting even better results with consistent use. Just remember to mix only a small amount with a product that suits your skin!

  Cons

  When I first used it, my skin felt a bit tingly. Sometimes if I don't control the amount well and use too much powder, it can cause a tingling sensation on the skin.

  Pros

  Using this product definitely brightens my complexion and fades blemishes. I bought it for the scars, and I'm quite satisfied with the results.

  Cons

  It's extremely drying. Even when I mix it with a cream, the cream becomes like a weak emulsion with poor hydration. At first, it felt a bit grainy on my skin, though this sensation disappears over time. The bottle opening makes it difficult to control the amount dispensed. As a side note, the packaging arrived damaged. While the product itself was fine, it left me feeling a bit uneasy.

  Tip

  Make sure to boost your hydration routine when using this.
