    I've been using this consistently for about three weeks. The way it absorbs is quite nice. I have normal skin, so I'm not sure about how well it absorbs.
    I stopped using it for two reasons: 1. I couldn't notice any effects 2. It was too sticky

    - I noticed an overall improvement in my skin condition. Rather than seeing specific areas get better, it felt like my skin as a whole was improving. I liked this aspect so much that even though I didn't see the brightening effects I expected, I repurchased and am still using it. - Despite having a watery consistency with no stickiness, it provides great hydration. For those with oily skin, you could probably finish your routine with just this, without adding a cream on top. In fact, using an oil-based cream afterwards might feel a bit too heavy. - I noticed many reviews mentioning the scent, but that wasn't something I even thought about. If you're not sensitive to fragrances, it probably won't be an issue for you.
    - It stings quite a bit when you first apply it. As you continue using it, your skin seems to adapt and the tingling sensation goes away. However, while there was some discomfort, I didn't experience any blemishes or redness. - I didn't notice any brightening effects at all. To be honest, brightening and improving dark spots were what I was most looking forward to when I bought this product, so I was a bit disappointed in that regard. - Since it's a Vitamin C serum, it needs to be refrigerated. I didn't store it in the fridge at first, and it oxidized, so I had to throw away what was left. I always make sure to apply skincare products with clean hands, so having to open the refrigerator to get it out after showering was a bit inconvenient.
