  Pros

  The quantity is more generous than expected, and it lasted quite a while. While I'm not sure about the vitamin effects, I've been using it consistently. It's best applied by mixing it with an emulsion or cream-like thin formulation.

  Cons

  After prolonged use, I noticed the opening started to discolor. The powder also clumped a bit, causing some blockage.

  I mix it with my serum and I'm pleasantly surprised by how long it lasts due to its generous amount

  Cons

  Sometimes the powder can clog the tube opening, so make sure to give it a good shake to prevent blockage

  Pros

  This stuff is magical... Even with infrequent use, I've seen results. Since it can be irritating if used too often, I don't use it much, but even the small bottle lasts forever. While claims about fading freckles or melasma might be a stretch, it definitely improves acne scars in a short time. I use it on both face and body (see tip below). I also mix it into sheet masks occasionally. Just squeeze the essence from the mask into a clean rubber pack or glass bowl, add the powder, mix, spread on your face, then apply the sheet. The adjustable nozzle and light-blocking brown bottle are also praiseworthy.

  Cons

  It's quite potent, so I only use it about once a month. Naturally, it should only be applied at night.

  Tip

  It dissolves best when mixed with oil-free products. If using [B. moisturizer with oil], either: 1. Mix the powder with [A. toner, essence, or serum], pat it in, then apply B, or 2. Mix A and B together if you're feeling lazy. I use the latter method for body cream too, and sometimes in sheet masks. However, I don't use it daily to avoid irritation.

  Pros

  I bought this for my home skincare routine! A little goes a long way, so it seems like it'll last longer than I expected!

  Cons

  I do feel a slight tingling sensation when I use it, which can be a bit irritating. I'm also a bit worried about oxidation over time.

  Pros

  Hmm... The good point is that it slightly brightens the skin? But it seems like you need to use it for a while... Probably need to stick with it for some time.

  Cons

  After using it for a while, I think I'm getting some small blemishes. Also, there's a metallic smell... I might give it another try later!

  Tip

  It might not be a golden tip, but... mixing it with a hydrating moisturizer seems to work well...

  Pros

  I definitely feel like my skin is brightening up! When I consistently applied it every day at first, I noticed it was making a difference. It even seemed to lighten some of my pigmentation. However, it can be a bit of a hassle to use daily. Still, I've recently committed to using it regularly. Since you're supposed to dilute it 20 times, the amount is generous - it'll last ages! My routine is to apply toner, mix this with my serum, wait a bit, then layer on cream before bed.

  Cons

  It's tricky to get the right amount and figure out how much to mix. The whole mixing process itself can be a bit of a pain.

  Tip

  I also mix it into my body emulsion and apply it all over. It's especially good for areas that tan easily or are darker than the rest, like elbows, hands, and the tops of my feet.

  Pros

  When I apply it before bed, my skin feels incredibly soft the next morning. It seems to help my makeup adhere better, and my skin feels more hydrated. Although I don't use it daily due to laziness, and I don't use a large amount, it lasts quite a while. I always make sure to use it the night before heavy makeup because it makes my skin so smooth!

  Cons

  It's a bit annoying when too much powder comes out, as it's troublesome to dissolve. Shaking the powder puff to get the product out can also be a hassle. I'm not sure if it actually brightens my complexion.

  Tip

  Instead of using it as a dry powder, try mixing it with a fluid emulsion or hydrating moisturizer for easier application! I would consider repurchasing when I run out, but not specifically for brightening purposes.

  Pros

  It lasts for ages! The amount is easy to control, and the ingredients are great. My whole family is using it, and it still lasts a long time. Compared to other products, you can definitely control the amount better and use it for longer, which is fantastic.

  Cons

  The moment you lose the cap, dust can accumulate or if moisture builds up, the hole can get clogged.

  Tip

  I mix it with toner before applying.

  Pros

  What a steal! The amount you get for this price is incredible. I'm using just a tiny rice-grain sized amount, so it'll last ages. I should check the expiration date though. Everyone knows vitamin C isn't very stable, right? Don't get greedy with it, ever! I just tap out a rice-grain sized amount and mix it with my serum before applying. Last season, I had a terrible breakout of cystic acne. After taking meds and getting extractions at the dermatologist, I was left with awful scars. I looked into spot-fading serums, but wasn't happy with the ingredients. I bought this somewhat skeptically, mixed it with my favorite serum, and now the scars are almost gone! Don't overdo it though! If you apply too much and get blemishes, you'll end up with more scars. Then you'll use more to fade those scars, get more blemishes... It's a vicious cycle. For scars, the most important thing is preventing new breakouts!

  Cons

  No complaints at the moment! The amount you get for this price is amazing. Very satisfied! I should check the expiration date though.

  Pros

  At first, I was on the fence about buying it... But my acne scars and blemishes were really getting me down, so I decided to give it a try. And wow, I can definitely see the results - my marks are gradually fading! My nails have turned a bit orange, like I've been peeling tangerines, which is a bit odd. But that actually makes me confident the vitamin C is really working its magic! Plus, you get so much product that even after sharing some with a friend, I still have over half left. It'll last ages!

  Cons

  The powder dispenser hole is just too small... It's a bit frustrating.

  Tip

  When mixing, it's best to use a spatula or something similar. If you mix with your fingers, it'll stain them. Also, while my usual emulsion feels moisturizing, this one can feel a bit drying when it sets. I'd recommend applying a cream or something extra on top for added hydration.
