    Pros

    I've been using it for over a month now. It's a combination skin type, leaning more towards oily. The scent gives the impression of a high vitamin content, and while vitamins alone can be drying, the inclusion of hyaluronic acid provides a more moisturizing effect. After application, I find that my makeup applies better the next day. There's a sense of refinement in my skin texture and tone.

    Cons

    The fact that it contains vitamins may be why it feels like it's not being managed properly and can become rancid. It takes a while to absorb and is stickier than expected. When you just wipe it off with a toner the next morning, a bit of yellow comes off. It seems like it's not being fully absorbed.

    Tip

    Apply the vitamin serum and then layer a moisturizing cream on top. This actually makes it feel a bit less sticky, and the hydration helps stabilize the skin a little more.

    Pros

    The vitamin serum I used was not overly irritating.

    Cons

    The effect of brightening the skin is minimal. I think I need to use it consistently to see the results.
